I've been using five subs in a distributed bass array ever since learning about Geddes research many years ago. Great video, but two things unmentioned that are very hard to convey and get anyone who hasn't done this to believe: one, with four subs placement becomes much less important to the point it is trivial. Four subs results in so many much lower level modes being distributed around the room that bass becomes flat even without doing anything. Especially if you are able to locate them asymmetrically, that is, each one a different distance from a corner, and also different than the mains. And two, the smooth articulate and effortlessly powerful low bass produced by a DBA creates a sense of spaciousness and envelopment that is impossible to believe. You just have to experience it for yourself. When I first did mine there was one time I put on Tracy Chapman to enjoy the terrific low bass, only the first track I thought had no low bass- yet it sounded completely different! Tremendous sense of space and envelopment that simply was not there when the DBA was off. As if the room walls melted away and you were there in the studio instead. This even in spite of the fact there was no discernible low bass! Finally, when using just one or two subs their quality and power is very important. When using four each sub is putting out so much less power that this is just not all that big a deal any more. You didn't explore this, but you are much better off using four small cheap subs than one or two much bigger more expensive and powerful subs. Hard to believe but test it and you will see, er hear, for yourself!
I fully agree but I don’t have the room in my living room currently to do this. I will be moving into a new house in a couple months and am eager to set up my new listening room with multiple subwoofers. Appreciate the tip on asymmetry I never considered that.
I tried moving my single Rythmik F12G subwoofer away from the floor standing speaker toward the middle as much as my setup allows after watching this. The change was definitely a noticeable improvement in bass and soundstaging. Thanks so much for this. Very helpful.
For bass lovers, Christmas came a few days early. Thanks, Ron! Although having 4 subs measured better than 1 or 2, I preferred the 2 Double Trouble setup's texture and tone. Four Double Troubles would be even better.
Thanks Ron. Excellent tutorial for peak integration and performance.of subs with mains. Two caveats that some may need to consider. #1 For those using smaller bookshelf speakers (4-5.5" single bass driver on speaker) the sub crossover may need to be set at 100-110hz in order to deliver more bass impact (sub placement will be quite tricky at such a high cross over). #2 Caveat: For those who want a large scale dynamic presentation of their music, while using speakers that start distort above 85 dbs, crossover on both subs and mains at 100-120hz (mini dsp or amp with built in sub management will be required) .
I bought a REL 1205 mk2 sealed sub and placed it in the middle of my speakers to start, adjusted the knobs a few times and it was perfect. I know having multiple would be better but honestly it’s such a huge improvement that when it’s off I feel everything sounds wrong lol. Great video Ron, it’s definitely impressive what more subs can do 👌
Good stuff Ron. I would've also mentioned setting a house curve. Most of the time, aligning the subs flat to the mains will not yield enough in room bass and everything
I've had my REL T0 sub between open baffles for a while now -- it's raised about 18" from the floor on a wooden stool where its downward-facing driver is on a level with the centre of the 15" full range drivers for the O/B's. For me, the benefit of a sub isn't just for the bass. I think it makes for better, more holographic, engaging and atmospheric sound right across the frequency range. Don't know why that should be, but it's my subjective observation.
Absolutely fantastic video Ron! I have been searching all over the place trying to find something like this and to no avail, nothing. Now I’m really not sure if I’m ready to spend over $5000 on a pair subwoofers to get the achieved results, but if I start saving up now, as long as I only have 1 foot in the grave, my ears will still be above ground. Thanks again.
@@PP-nh1lv I meant the single sub worked best in the audio examples, at least the most noticeable. When I placed the sub in my friend's studio I did simulations and the optimal place would have been behind his chair, but that wasn't an option. Second best option was in the corner with the woofer aimed at the side wall, the speakers pretty close to the back wall (was also necessary because of space reasons). You can use REW to simulate your room and move the speakers and sub around to see what would happen more or less. Also measure of course
To me, it sounded like a good deal of clarity in the mids and highs got lost with subwoofers. Everything but the lows sounded a little muffled. I think I would have turned down the subs a tiny bit more. Preferred the double troubles, the Arendals were a bit overpowering for my taste. Great video, and marry Christmas. 🥳
High passing your mains will lower distortion and increase headroom. Taking the bass load from the often little midwoofers delivers better sound overall.
The thing is that most people dont understand how to set up Subwoofer correctly and what for example is the sense behind an Double Bass Array is. Subwoofers (when set up via DSP correctly) acting like Active Roommode Compensation Devices. Thanks for the video, wish more ,,Stereo,, Channels look a little bit deeper in different Setup Types & Concepts. I had this week an discussion with an Hifi / High End Dealer wich also have an TH-cam Channel, and his mindset about DSP, Measurements/REW, Subwoofers are so far behind that you cant argue sometimes with those people about ,,newer,, tech and ways of music listening. I use four Subs (thinking about more) and its awesome to hear the ,,unlimited,, power from the whole setup because the main speaker dont need to work hard (and i use Neumann KH150 for Music & Hometheatre, wich can go extremly loud for their size but still prescise)
I use an Atmos Pre Amp / DAC with 4x Sub Outputs. From there XLR to the Speakers (Active) and XLR to the ImgStage Line PA Amp for the Subwoofers (DIY Scan Speak). Works perfectly. Without any Pre Amp outputs, just an Stereo amp where you just can plug in a Pair of Speakers its difficult. Its not easy with normal Stereo Based Amplifiers. When you buy Pre Made Subs you can use High Level Input but its not the best option
Good question I am also interested to know Ron’s setup - line level, channel splitter or seperate outs from DAC, minidsp, sub pre-outs etc etc - lots of options that can influence approach. I use second set of line outs to left and right sub and amplifier for mains from my benchmark dac3L
Great video. I have never heard open baffle before and I was impressed by the lack of boominess. Very fast and articulate. How were the subs connected to the source components? Also, I would love to see the track listing used for the demos.
Thanks for sharing your experience and knowledge. I’ll be moving my single REL T9 in between my speakers from its current location next to my left speaker.
Hi Ron, I have main stereo speakers that are about 50 litres per cabinet with twin 8 inch drivers. The cabinets are dual chamber bass reflex and I have them in an extensively acoustically treated listening room. The bass is fantastic quality and very extended. I don't feel the need for a sub woofer. Some time ago my neighbour complained that my system made her whole house shake. What is your opinion on dual chamber bass reflex? My speakers were designed by Dr Paul Mills.
I always assumed that aligning the subwoofer "phase" with the main speakers isn't about having all the transducers in sync, but compensating for the distance difference between the components, so that at the listening position the fundamental in low freq (sub) arrives at the same time (in perfect phase) with the harmonics reproduced by the monitors avoiding the comb filtering in the overlapping domain.
These sound examples are big effort to produce I guess (thanks for doing it!) and at the same time they don't give me this immersive effect that I get from subwoofers in my room. The feeling how the whole rooms swings at low frequencies on a low note fading out of a well recorded grand piano - these YT recordings and my headphoes cannot reproduce that. Not in the slightest. It's a whole different world, reality on subsonic sounds and headphones.
forget about headphones, i use my hifi for youtube and subwoofers shake things like deep sounds should. also a microphone can not convey the differences in spl, so two different size subwoofers playing at same volume sound the same when in reality it does not.
Good question, he did not explain this. I was assuming the mains had no crossover and he just worked with their natural high pass behavior, but maybe not
Very good video even if it's not "fair" to judge for example among one sealed sub vs two open baffle subs.... It would have be obviously more difficult and time demanding comparing one sealed vs one open baffle vs two sealed vs two open baffle. I'm not mentioning four sealed vs four open baffle, I care for your back 😂. Thanks for sharing this and especially to focus on measuring the various configurations. Personally I preferred the 2 subs, not boomy and very accurate. Thanks again!
a good starting point, hope this video helps a lot of people in hifi and bass :) i have a mic and rew, use it and still i end up with tune by ears in the end. but i do have Realtime dsp from listening position. with online tone generator for gain matching and some punchy bass music for phase adjustment you can get far. anything sensible graph my UMIK-1 draws is not what my ear want to hear so i am putting that out there in case anyone else benefit from this. my ear tuning sound better is my point. all depending on the room, speakers and preferences/references of course. and while you are at it with dual subwoofers are they in stereo? because in that case if you can put high pass on those stand mount speakers, increasing the work the subwoofers do up in frequency is the holy grail for that large speaker sound. so it wont sound like a small speaker at 50hz and then huge subwoofer below that. there are some amazing guitar music that tingles the bones high up in the 120hz that small mains and large subwoofers wont get right until you let subwoofers play up high. the large main speaker effect if you will.
For my room shape and geometry, placing 2 subwoofers behind/close to main speakers didn't worked out. I had a huge 20db null on 35Hz. Placing the subwoofers diagonally resolved the issue on 35Hz and got very smooth response from 20Hz to 100Hz(±3db) without any DSP. I'm using 2 RELs HT1205 MKII.
I question the overall relevance and accuracy because of the common settings and crossover point required for LFE and THX/high definition surround sound. That is 80 Hz for the subwoofer. And you can use Dirac for the surround sound speaker setup, and a mini dsp box for the subwoofers. I have always used the 80 Hz setting crossover point for all subwoofers with no issues.
If you understand and appreciate the full "audio" spectrum then having +20 db at 16Hz should be seriously considered. Aside from REW you should also be familiar with "Multi-Sub Optimizer". Latest release is Version 2.1.1: Released 2024-12-04
To my ears the single sub had the most effect, it could even be turned down a little compared to the examples with more subs. Two subs seemed to cancel out a bit more or something. Four subs sounded most controlled but didn't have the same boom as the single sub (on the dummy head at least)
i heard the same thing, and the open baffle subwoofers had no deep bass compered to the sealed ones even though the measurement shows its the same. but the microphone does not pick up "spl" but only decibel if that makes sense.
A few questions 1.For measuring the subwoofer/speaker do you keep the noise at "pink random" or "pink periodic" in the generator tool? 2. Also do you use full range or sub cal or speaker cal while measuring the 'Subwoofer' in the generator tool? TIA. Regards.
Every stereo audiophile system should use a subwoofer. Playing with subwoofers for 4 years founded how much spacial information we lost without them and how IMPORTANT is time alignment or phase alignment.
Thanks for your work mate, love your content😊 I actually liked the one sub sound best (makes ZERO sense to me🙊🙈🙊, I use 3 subs myself, 2 front 1/4 from sidewalls each side, and one elevated kind of in the middle of the backwall both in height and width). I was expecting to like more subs better, as I do in my setup, as I said; makes no sense to me🙈 I found the sound to become too dry, to precise with more subs, and that is probably the more "correct" sound. All sounded really good though, and I will never go back to single sub. Again, thanks for the work you do, peace out🤘🤘🤘
I think these are the new GR research/New record day spearkers . There should be a rear firing small driver as well. Danny said they will be selling them as a completed speaker sometime soon.
With or without subs, the system sounds peaky between 70hz, and 125hz. I think that thats an issue to be addressed. The open baffle subs are like listening to no subs.
I am old school where it was believed that speakers shouldn't need subwoofers, but my opinion is slowly changing to accept that subwoofers can be part of a music system. Part of the problem is in the early days of subwoofers they were boomy and didn't integrate well with speakers, so no self respecting audiophile would try and join the two. But just like class D amps in music, times are a changing and it is not quite the sin it once was. Maybe next year is the time to give it a go.
I must admit I listened through my speaker system QUAD ESL 57 and two passive 15” DIY dipole subs (in 100 cm deep H frames made of recycled oak): But the boxed subs were terrible timing wise. The bass was smeared all over the music. Like drawing using a spray can rather than a sharp pencil. The dipole subs sound very accurate, like I prefer. And they stop on a dime, as they should. But I would prefer more complex music than the audiophile but musically in intersting stuff you used. The full range system should be able to play stuff like Queen loud, or jazz like Ben Webster At the Rennaisance or Decca operas convincingly. Why not demonstrate that?
Good video overall. A measurement based approach is the best thing you advocated for in the video. Ultimate? No way. Ultimate is a sub in each corner of your room optimized with Multi Sub Optimizer and a Minidsp ( or one of the new wave forming solutions). My systems bass is epic as a result of the approach above. This also optimizes for multiple seats unlike your approach Ron. This means any seat on my listening couch has tight, punchy, extended, musical bass.
Thank you Ron! For calibrating my (single) Sub (SVS SB-2000 Pro) I used the SVS app. Currently with no additional software or microphone. I am far from having golden ears but I think the method I describe below is OK and sufficient, at least for my case. I assume of course no bass management in amp. Here are the steps: 1. At the SVS app - chose polarity and set to “Negative”. That’s right we temporarily set the polarity to negative just for calibration. 2. At app select “Low Pass Filter” disable LFE and set the LP frequency to match the -3dB settings for the main speakers. Select slope in accordance to speaker. SVS recommends 24dB/octave for ported mains or 12 dB/octave default. Later on we can tune it further but these should be the initial settings. (For example my mains have -3dB at 40Hz and they are ported). 3. Play a test tone the LP frequency you selected in (2). For example in my case I played a 40 Hz test tone. (There are many test tones in TH-cam) 4. At the app - slide the the phase from 0 to 180 and stop to the point where the test tone volume is minimal. 5. At the app - increase or decrease volume of the sub-woofer until the test tone volume is minimal. 6. Repeat steps 2, 4, 5 until you hear NOTHING at your listening point. The tone from the mains and the tone from the sub cancel each other! That means that they are at the same phase and volume but opposite polarity. The process is iterative. Expect some trial and error iterations. Once you are satisfied proceed to next step. 7. At the app - return the polarity back to Positive. 8. Listen to music and set the volume of the sub-woofer to your liking. You can repeat the steps above for tunings, just don't forget to return the polarity back to positive. Note that the -3db point the loudspeakers manufacturer gives, might be different in your room. For example in my case, the manufacturer gives 40 Hz but when I do this method with 40 I get too much base. I lowered the low pass to 37 and now it's OK.
Graphs are smoothed out too much. And at 20:26 nobody should call that linear/smooth response while having -13dB around 27Hz. Quick/clean bass is mistakenly labeled bass without lowest frequencies. Subs needs dsp. That's it.
The thing is that most people dont understand how to set up Subwoofer correctly and what (for example) is the sense behind an Double Bass Array, Single Bass Array or Multi Sub Config is (and how you calculate it). Subwoofers (when set up via DSP correctly) acting like Active Roommode Compensation Devices. Thanks for the video, wish more ,,Stereo,, Channels look a little bit deeper in different Setup Types & Concepts. I had this week an discussion with an Hifi / High End Dealer wich also have an TH-cam Channel, and his mindset about DSP, Measurements/REW, Subwoofers are so far behind that you cant argue sometimes with those people about ,,newer,, tech and ways of music listening.
I’m in the same boat as you, my friend. Took my 4 subs and moved from corner loading to a DBA and have zero desire to look back. The absolute best bass you could ever have is only possible through either hundreds of thousands of dollars in specific room construction and treatments or a DBA. I literally had my setup reconfigured in about 45mins to a usable DBA. I’ve since retuned it multiple times to eke out every bit of performance I can just to see what’s possible. My bass from 20hz-150hz decays 50db in under 125ms and has a ruler-flat response in unsmoothed graphs in REW. You literally can’t beat a DBA.
Setting up "a" sub is a process, a challenge, and ultimately never gets the job done. Ever. Setting up four subs is simple, easy, and always produces stellar SOTA results. Choose wisely.
@@G3rain1 Look up HRTF. Dummy head recordings work best on in-ears by the way. Even better when the dummy head has the exact shape of your specific ears and distance between them.
he did not go into that, so many people trying this guide might get a delay of one cycle on their subwoofer. that is pretty normal but i hope time alignment is getting more attention to address this.
@ I don’t understand how someone could claim they understand subwoofer setup without going over time alignment. It completely disconnects the sub from the system if not done
@@t.j.bennett6454 i think he understand some of it, its just a too short video to explain everything. and the target of the video is people with stereo hifi and active subwoofer with no dsp. and if you never heard a subwoofer in phase and time before then that is your reference. even i though that was great before i experienced better. but its hard to fix it without dsp in main speakers.
@ saying “I think understand some of it” is literally just presuming because no where in the video did he indicate that he even hint at anything time alignment As far as too short to explain everything, the title of the video is “The ultimate guide to audiophile bass | Mastering subwoofers!”
How much latency does the DSP incur? If it's a few milliseconds, you might actually want to place the subs closer than the bookshelfs for time alignment
Thanks Ron. I do think the room dominates, to the point that any placement scheme is likely not the ideal way to go. Personally using measurements for placement was a total game changer for me. This included doing real time analysis using pink noise, with the measurement mic in the listening position, while moving the sub around on a dolly to find best candidates 😊Then follow up with sweeps to find “the one”(position), being mindful of the time domain in addition to amplitude curves. But first I really need to find the best listening position for bass, which was done by placing a single speaker in a corner and walking the room swinging the mic in a small pattern, again while playing pink noise and using the real time analyzer. With everything in the Goldilocks position, exact crossover point and sub gain becomes so much more forgiving and no more constantly turning the sub up and down, depending on program material. Now, I’m a subjectivist all day long, but moving my setup into a small bass challenged room, sent me down this path after trying maybe 6 different dual sub setups. In the end my bass is better than it’s ever been and honestly I could do without the 2 sub, which was a total necessity with the more “analog” approach to placement.
The sealed sub provided the most impactful sound with a huge difference vs no sub. The OB sound much more detailed though not as deep. All 4 gave the perfect combination 😍 👌
Thanks for another great, informative video. It must have taken a lot effort to move the subs around, measure and put together the clip. I’ve heard a noticeable difference (using airpod pro earphones) in each case but diminishing returns. As a yardstick, if the no-subs would be 1 in base response, single sub would be 2, two subs would be 2.5-3 and four subs would be 3-4. I believe that is expected.
. Sub-Woofers aren't for musical instrument playback. They're for synthetic sounds & low frequency movie effects. Ron's using them here at a cross above 40Hz, which is adding Mono bass (no imaging) to non-full range 2-way stand mounts. Go back and watch Ron's review of the GR-Research 3-way 'Brutes'. They are full range and need no subwoofer to fill-in the missing bass, including stereo imaging, for instrument playback. Acid Jazz, Funk & Brass🔈🔉🔊
Another interesting addition to all of these arrangements would be to perform a Dirac Live calibration since the binaural recording using the Neumann KU 100 head should be able to show the effect of with Dirac and without Dirac.You would need the DSP equipment (MiniDSP or equivalent) to perform this. That would be a very interesting addendum to all the hard work you did here.
Great video and quite informative. Big difference with no subs vs with subs. Very little difference between 1, 2 or 4 subs that I could make out. Maybe the Arendal subs gave a slight increase in depth. Probably a different story listening in room. I will chalk that all up to either your mastery at integrating them into the system or the dreaded youtube compression algorithm. It could not possibly be my 52 yr old ears with a lifetime of loud music and working with heavy equipment, listening on Bose QC 35 headphones. Your vocals were pristine though. Yay mids!!
Holy crap, double sub approach already sounded amazing. This was super helpful! Looking to add a sub (for two subs). Side question (please forgive but) will we get a comprehensive review of the new NX-Bravos? Curious about how that planar sounds in that configuration 🙏🏼
I've caught quite a few bass , they make a really deep thump when they the hit the floor of the boat. And I have treble hooks on all my lures. Used to have a state of the art boat but I sold it and bought something more mid range. When I get my depth sounder facing in exactly the right direction its image opens right up and becomes almost holographic.
I find subs distracting. Give me a well-designed full-range speaker, and I'm happy. There isn't anything musical below 30Hz I'm interested in. Theaters for sound effects, sure.
Agreed. Only if you reeeally can only fit small bookshelf speakers between you and the wall and need to put a sub someplace else it makes sense, or like in case of a 5.1 surround system or soundbar because the spouse hates speakers. If you can fit 2 subs in your room and budget, you can fit 2 full-range speakers in them.
If subs are distracting then they are not set up correctly. You can tune subs to be seamlessly integrated with mains. Sure many people are good without bass slam. Not me or many others. Most small medium size towers can’t play 30-40 HZ with authority. I like that lower octave to have some guts. Like you said room size has a lot to do with it. My bedroom system stand mounts have enough bass. My listening room has two 12s ported tuned to 35HZ and most music you don’t know they are on. listening to metal, EDM or rap they come alive. Fully pressurizing the room.
@ That's one way of looking at it. I would say, what's wrong with your full-range speaker that you need a sub? Having said that, if EDM and Rap are your thing, then the body vibrations you get from a sub make perfect sense.
I've watched many, many videos on this topic and Ron's brings this to a new level. Thank you for your presentation! I learned a great deal and having the sound clips, presenting as you did were very revealing.
What if you have subs with opposing woofers? Do you face them with one towards the listening position (and the other facing away) or turn the sub 90 degrees so the woofers are pointing sideways from the listening position? Or...is it just a matter of taste (or maybe measurements)?
I dont have a balance control on my amp. So is it safe to disconnect one set of speaker cables ? If you have disconnected one side, did it cause any problem ?
Happy holidays, Ron! Hope you and the family have a wonderful Christmas and a happy New Year. 🔊🥳🎶🎄💜🎅 “Randy Neuman” 🤣 Not sure I’ve heard his last name before. He just keeps getting more handsome with age…. Thanks, Ron. Another home run of a vid. Appreciate you, man.
Your single sub advice only works because you have an amazing response in your room to begin with ! Anyone with huge peaks and nulls in their room (the other 99.9%) this will only make worse and thus "bad advice". The single sub can be anywhere that the gives the flattest response period ! I use my little SVS micro 3000 sub to fill in the SBIR dip(s) while still running the main speakers (Arendal 1723 towers) full range. You totally missed on this point IMHO. SVS also has one of the best Apps for dialing in the sub phase and EQ. And while we are on subs, who gives a rats ass about bass below 40Hz ? Most music has little or no energy there. I was thinking about downloading one of the audio clips and run a spectral analysis. Would probably have very little below 50hz aside from some subsonic garbage in the 5-20 Hz range. The last thing I want listening to music is hearing the walls rattle !
I've been using five subs in a distributed bass array ever since learning about Geddes research many years ago.

Consider microphones are the limiting factor here.
High passing your mains will lower distortion and increase headroom. Taking the bass load from the often little midwoofers delivers better sound overall.
Plus your receiver, or integrated will work a lot less, let the ‘cheaper’ plate amps do the heavy lifting.
The thing is that most people dont understand how to set up Subwoofer correctly and what for example is the sense behind an Double Bass Array is.

I had this week an discussion with an Hifi / High End Dealer wich also have an TH-cam Channel, and his mindset about DSP, Measurements/REW, Subwoofers are so far behind that you cant argue sometimes with those people about ,,newer,, tech and ways of music listening.
I use four Subs (thinking about more) and its awesome to hear the ,,unlimited,, power from the whole setup because the main speaker dont need to work hard (and i use Neumann KH150 for Music & Hometheatre, wich can go extremly loud for their size but still prescise)
How did you connect speakers and subs? Did you use any kind of preamp/receiver? What did your setup and connections look like? Thanks
I use an Atmos Pre Amp / DAC with 4x Sub Outputs. From there XLR to the Speakers (Active) and XLR to the ImgStage Line PA Amp for the Subwoofers (DIY Scan Speak). Works perfectly. Without any Pre Amp outputs, just an Stereo amp where you just can plug in a Pair of Speakers its difficult. Its not easy with normal Stereo Based Amplifiers. When you buy Pre Made Subs you can use High Level Input but its not the best option
Good question I am also interested to know Ron’s setup - line level, channel splitter or seperate outs from DAC, minidsp, sub pre-outs etc etc - lots of options that can influence approach. I use second set of line outs to left and right sub and amplifier for mains from my benchmark dac3L
Great video. I have never heard open baffle before and I was impressed by the lack of boominess. Very fast and articulate. How were the subs connected to the source components? Also, I would love to see the track listing used for the demos.
Thanks for sharing your experience and knowledge. I’ll be moving my single REL T9 in between my speakers from its current location next to my left speaker.
Hi Ron, I have main stereo speakers that are about 50 litres per cabinet with twin 8 inch drivers. The cabinets are dual chamber bass reflex and I have them in an extensively acoustically treated listening room. The bass is fantastic quality and very extended. I don't feel the need for a sub woofer. Some time ago my neighbour complained that my system made her whole house shake. What is your opinion on dual chamber bass reflex? My speakers were designed by Dr Paul Mills.
I always assumed that aligning the subwoofer "phase" with the main speakers isn't about having all the transducers in sync, but compensating for the distance difference between the components, so that at the listening position the fundamental in low freq (sub) arrives at the same time (in perfect phase) with the harmonics reproduced by the monitors avoiding the comb filtering in the overlapping domain.
Great job, Ron! I’ve been holding off doing this but now you’ve inspired me. Really appreciate it.
Great video. I have been using multiple subs for 15 years now.
I do think and active crossover with a highpass would take it even farther.
These sound examples are big effort to produce I guess (thanks for doing it!) and at the same time they don't give me this immersive effect that I get from subwoofers in my room.
The feeling how the whole rooms swings at low frequencies on a low note fading out of a well recorded grand piano - these YT recordings and my headphoes cannot reproduce that. Not in the slightest. It's a whole different world, reality on subsonic sounds and headphones.
forget about headphones, i use my hifi for youtube and subwoofers shake things like deep sounds should.
also a microphone can not convey the differences in spl, so two different size subwoofers playing at same volume sound the same when in reality it does not.
Do the arendals handle the crossover? Like are your speaker cables running into the subs first and then to your speakers?
Good question, he did not explain this. I was assuming the mains had no crossover and he just worked with their natural high pass behavior, but maybe not
Very good video even if it's not "fair" to judge for example among one sealed sub vs two open baffle subs.... It would have be obviously more difficult and time demanding comparing one sealed vs one open baffle vs two sealed vs two open baffle.
I'm not mentioning four sealed vs four open baffle, I care for your back 😂.
Thanks for sharing this and especially to focus on measuring the various configurations.
Personally I preferred the 2 subs, not boomy and very accurate.
Thanks again!
Love this. Also am I the only one who wants track ids? Did I miss the link? I feel like these would be good tests
a good starting point, hope this video helps a lot of people in hifi and bass :)
i have a mic and rew, use it and still i end up with tune by ears in the end. but i do have Realtime dsp from listening position.
with online tone generator for gain matching and some punchy bass music for phase adjustment you can get far.
anything sensible graph my UMIK-1 draws is not what my ear want to hear so i am putting that out there in case anyone else benefit from this. my ear tuning sound better is my point. all depending on the room, speakers and preferences/references of course.
and while you are at it with dual subwoofers are they in stereo? because in that case if you can put high pass on those stand mount speakers, increasing the work the subwoofers do up in frequency is the holy grail for that large speaker sound. so it wont sound like a small speaker at 50hz and then huge subwoofer below that.
there are some amazing guitar music that tingles the bones high up in the 120hz that small mains and large subwoofers wont get right until you let subwoofers play up high. the large main speaker effect if you will.
For my room shape and geometry, placing 2 subwoofers behind/close to main speakers didn't worked out. I had a huge 20db null on 35Hz. Placing the subwoofers diagonally resolved the issue on 35Hz and got very smooth response from 20Hz to 100Hz(±3db) without any DSP. I'm using 2 RELs HT1205 MKII.
Hi Ron thank you for all your valuable info and hard work. I do have a question: is it best to do this before or after treating your room?
I question the overall relevance and accuracy because of the common settings and crossover point required for LFE and THX/high definition surround sound. That is 80 Hz for the subwoofer. And you can use Dirac for the surround sound speaker setup, and a mini dsp box for the subwoofers. I have always used the 80 Hz setting crossover point for all subwoofers with no issues.
If you understand and appreciate the full "audio" spectrum then having +20 db at 16Hz should be seriously considered.
Aside from REW you should also be familiar with "Multi-Sub Optimizer". Latest release is Version 2.1.1: Released 2024-12-04
To my ears the single sub had the most effect, it could even be turned down a little compared to the examples with more subs. Two subs seemed to cancel out a bit more or something. Four subs sounded most controlled but didn't have the same boom as the single sub (on the dummy head at least)
i heard the same thing, and the open baffle subwoofers had no deep bass compered to the sealed ones even though the measurement shows its the same.
but the microphone does not pick up "spl" but only decibel if that makes sense.
A few questions
1.For measuring the subwoofer/speaker do you keep the noise at "pink random" or "pink periodic" in the generator tool?
2. Also do you use full range or sub cal or speaker cal while measuring the 'Subwoofer' in the generator tool?
TIA.
Regards.
I hate periodic pink noise 😅
What’s that track with the drums? Thank you
Every stereo audiophile system should use a subwoofer. Playing with subwoofers for 4 years founded how much spacial information we lost without them and how IMPORTANT is time alignment or phase alignment.
Hey! What are the cabinets you have for your vinyl on both sides of the room?
Hello
What do you think about Dynaudio Focus 10
Great video! Thank you.
Thanks very helpful video.
Thanks for your work mate, love your content😊
I actually liked the one sub sound best (makes ZERO sense to me🙊🙈🙊, I use 3 subs myself, 2 front 1/4 from sidewalls each side, and one elevated kind of in the middle of the backwall both in height and width). I was expecting to like more subs better, as I do in my setup, as I said; makes no sense to me🙈
I found the sound to become too dry, to precise with more subs, and that is probably the more "correct" sound. All sounded really good though, and I will never go back to single sub.
Again, thanks for the work you do, peace out🤘🤘🤘
What standmount speakers are you using?
My guess is that this is a first glimpse of the new collaboration between Ron and Danny? The upper driver looks like his LGK wide-bander.
What are the main speakers you are using during this video?
What brand are the main speakers?
I think these are the new GR research/New record day spearkers . There should be a rear firing small driver as well. Danny said they will be selling them as a completed speaker sometime soon.
With or without subs, the system sounds peaky between 70hz, and 125hz. I think that thats an issue to be addressed.
The open baffle subs are like listening to no subs.
You can also notice how clean mids and highs get when you add a subwoofer.
Put the second pair on the opposite wall same distance from the back plane and put them out of phase
Yep, the Double Troubles sound amazing. Life goals.
What audio tracks?
Amazing video
Hey, Ron, what is the difference between the UMIK-1 and the UMIK-2 aside from price?
IINM, the UMIK-2 is required for the DIRAC enabled miniDSP devices, while the UMIK-1 or Dayton UMM-6 are quite adequate for the standard versions.
I am old school where it was believed that speakers shouldn't need subwoofers, but my opinion is slowly changing to accept that subwoofers can be part of a music system. Part of the problem is in the early days of subwoofers they were boomy and didn't integrate well with speakers, so no self respecting audiophile would try and join the two. But just like class D amps in music, times are a changing and it is not quite the sin it once was. Maybe next year is the time to give it a go.
I thought CheapAudioMan was gonna make an appearance 🤣
I must admit I listened through my speaker system QUAD ESL 57 and two passive 15” DIY dipole subs (in 100 cm deep H frames made of recycled oak): But the boxed subs were terrible timing wise. The bass was smeared all over the music. Like drawing using a spray can rather than a sharp pencil. The dipole subs sound very accurate, like I prefer. And they stop on a dime, as they should.
But I would prefer more complex music than the audiophile but musically in intersting stuff you used. The full range system should be able to play stuff like Queen loud, or jazz like Ben Webster At the Rennaisance or Decca operas convincingly. Why not demonstrate that?
Good video overall. A measurement based approach is the best thing you advocated for in the video. Ultimate? No way. Ultimate is a sub in each corner of your room optimized with Multi Sub Optimizer and a Minidsp ( or one of the new wave forming solutions). My systems bass is epic as a result of the approach above. This also optimizes for multiple seats unlike your approach Ron. This means any seat on my listening couch has tight, punchy, extended, musical bass.
Thank you Ron!
For calibrating my (single) Sub (SVS SB-2000 Pro) I used the SVS app. Currently with no additional software or microphone. I am far from having golden ears but I think the method I describe below is OK and sufficient, at least for my case. I assume of course no bass management in amp.
Here are the steps:
1. At the SVS app - chose polarity and set to “Negative”. That’s right we temporarily set the polarity to negative just for calibration.
2. At app select “Low Pass Filter” disable LFE and set the LP frequency to match the -3dB settings for the main speakers. Select slope in accordance to speaker. SVS recommends 24dB/octave for ported mains or 12 dB/octave default. Later on we can tune it further but these should be the initial settings. (For example my mains have -3dB at 40Hz and they are ported).
3. Play a test tone the LP frequency you selected in (2). For example in my case I played a 40 Hz test tone. (There are many test tones in TH-cam)
4. At the app - slide the the phase from 0 to 180 and stop to the point where the test tone volume is minimal.
5. At the app - increase or decrease volume of the sub-woofer until the test tone volume is minimal.
6. Repeat steps 2, 4, 5 until you hear NOTHING at your listening point. The tone from the mains and the tone from the sub cancel each other! That means that they are at the same phase and volume but opposite polarity. The process is iterative. Expect some trial and error iterations. Once you are satisfied proceed to next step.
7. At the app - return the polarity back to Positive.
8. Listen to music and set the volume of the sub-woofer to your liking. You can repeat the steps above for tunings, just don't forget to return the polarity back to positive.
Note that the -3db point the loudspeakers manufacturer gives, might be different in your room. For example in my case, the manufacturer gives 40 Hz but when I do this method with 40 I get too much base. I lowered the low pass to 37 and now it's OK.
Surround yourself in a cocoon of subwoofers and you will be in bass heaven. 😂😂😂😂😂
Graphs are smoothed out too much. And at 20:26 nobody should call that linear/smooth response while having -13dB around 27Hz.
Quick/clean bass is mistakenly labeled bass without lowest frequencies.
Subs needs dsp. That's it.
I use an active electronic crossover to integrate my subs. Makes sub integration quite easy.
Open baffle servo subs clearly are the way to go, for my money. Way less overhang, ripped definition! Thanks for presenting us with this, Ron.
The thing is that most people dont understand how to set up Subwoofer correctly and what (for example) is the sense behind an Double Bass Array, Single Bass Array or Multi Sub Config is (and how you calculate it). Subwoofers (when set up via DSP correctly) acting like Active Roommode Compensation Devices. Thanks for the video, wish more ,,Stereo,, Channels look a little bit deeper in different Setup Types & Concepts.
I had this week an discussion with an Hifi / High End Dealer wich also have an TH-cam Channel, and his mindset about DSP, Measurements/REW, Subwoofers are so far behind that you cant argue sometimes with those people about ,,newer,, tech and ways of music listening.
I’m in the same boat as you, my friend. Took my 4 subs and moved from corner loading to a DBA and have zero desire to look back. The absolute best bass you could ever have is only possible through either hundreds of thousands of dollars in specific room construction and treatments or a DBA. I literally had my setup reconfigured in about 45mins to a usable DBA. I’ve since retuned it multiple times to eke out every bit of performance I can just to see what’s possible.
My bass from 20hz-150hz decays 50db in under 125ms and has a ruler-flat response in unsmoothed graphs in REW.
You literally can’t beat a DBA.
Setting up "a" sub is a process, a challenge, and ultimately never gets the job done. Ever. Setting up four subs is simple, easy, and always produces stellar SOTA results. Choose wisely.
Those folks are the same who peddle REL subs. They live in the Model T era of audio. .
@@MyFatherLovesnice, what exact procedure you followed? Definitely cheaper than Trinnov Waveforming.
DBA???
Wear headphones to get spatial effects? Joking right?
splice.com/blog/what-is-binaural-audio/
Are you joking? Do you think your phones speakers are going to recreate the sound as recorded in his environment?
Nope, that’s what I mentioned to wear headphones 4-5 times in the video.
@@Newrecordday2013 That doesn't work. The music is still 100% inside your head.
@@G3rain1 Look up HRTF.
Dummy head recordings work best on in-ears by the way. Even better when the dummy head has the exact shape of your specific ears and distance between them.
have 6 good subs but only with Dirac Live multi-bass they (finally) get along 😂😂😂 can't praise Dirac enough 😊 but for music I use my HKSE these days
I’m surprised how low your crossover frequency ended up being. Great video. Getting out my laptop and mic soon!
What about time alignment?!
he did not go into that, so many people trying this guide might get a delay of one cycle on their subwoofer. that is pretty normal but i hope time alignment is getting more attention to address this.
@ I don’t understand how someone could claim they understand subwoofer setup without going over time alignment. It completely disconnects the sub from the system if not done
@@t.j.bennett6454
i think he understand some of it, its just a too short video to explain everything.
and the target of the video is people with stereo hifi and active subwoofer with no dsp.
and if you never heard a subwoofer in phase and time before then that is your reference. even i though that was great before i experienced better.
but its hard to fix it without dsp in main speakers.
@ saying “I think understand some of it” is literally just presuming because no where in the video did he indicate that he even hint at anything time alignment
As far as too short to explain everything, the title of the video is “The ultimate guide to audiophile bass | Mastering subwoofers!”
@@t.j.bennett6454 yea, i was annoyed also. but he had access to people who knows so he should have least put up a disclaimer.
How much latency does the DSP incur? If it's a few milliseconds, you might actually want to place the subs closer than the bookshelfs for time alignment
Thanks Ron. I do think the room dominates, to the point that any placement scheme is likely not the ideal way to go. Personally using measurements for placement was a total game changer for me. This included doing real time analysis using pink noise, with the measurement mic in the listening position, while moving the sub around on a dolly to find best candidates 😊Then follow up with sweeps to find “the one”(position), being mindful of the time domain in addition to amplitude curves. But first I really need to find the best listening position for bass, which was done by placing a single speaker in a corner and walking the room swinging the mic in a small pattern, again while playing pink noise and using the real time analyzer. With everything in the Goldilocks position, exact crossover point and sub gain becomes so much more forgiving and no more constantly turning the sub up and down, depending on program material. Now, I’m a subjectivist all day long, but moving my setup into a small bass challenged room, sent me down this path after trying maybe 6 different dual sub setups. In the end my bass is better than it’s ever been and honestly I could do without the 2 sub, which was a total necessity with the more “analog” approach to placement.
The sealed sub provided the most impactful sound with a huge difference vs no sub. The OB sound much more detailed though not as deep. All 4 gave the perfect combination 😍 👌
From the title I thought this was subwoofer placement for mastering 😂😂😂
Personally dual sounded best to me, four was too loud at certain parts with ringing overhang
okay Ron - What gives??? - This is the second video with GR-Research 'LGK Studios?' - So, now - maybe a video on the monitors; Please
Almost 100K !!! Happy Holidays!!
Thanks for another great, informative video. It must have taken a lot effort to move the subs around, measure and put together the clip.
I’ve heard a noticeable difference (using airpod pro earphones) in each case but diminishing returns. As a yardstick, if the no-subs would be 1 in base response, single sub would be 2, two subs would be 2.5-3 and four subs would be 3-4. I believe that is expected.
Bass is like Tabasco, too much and everything just tastes like Tabasco. But also, would you wanna live in a world without Tabasco? 😁
For deep hyperdynamic bass PLUS a crystal clear female voice check out Svanrand by Heilung. But be careful with the volume 😅😅😅
I am and have been, fully subscribed to this channel for YEARS. WHY TH-cam am I NOT GETTING new video notifications!!! 😡😡🤯
That’s concerning.
Once you have subwoofers you will never go back
One thing he didn't talk about was your center image just locks in the place.
. Sub-Woofers aren't for musical instrument playback. They're for synthetic sounds & low frequency movie effects. Ron's using them here at a cross above 40Hz, which is adding Mono bass (no imaging) to non-full range 2-way stand mounts.
Go back and watch Ron's review of the GR-Research 3-way 'Brutes'. They are full range and need no subwoofer to fill-in the missing bass, including stereo imaging, for instrument playback.
Acid Jazz, Funk & Brass🔈🔉🔊
@@TriAmpMyFi Obviously you've never owned a sub
Another interesting addition to all of these arrangements would be to perform a Dirac Live calibration since the binaural recording using the Neumann KU 100 head should be able to show the effect of with Dirac and without Dirac.You would need the DSP equipment (MiniDSP or equivalent) to perform this. That would be a very interesting addendum to all the hard work you did here.
Great video and quite informative. Big difference with no subs vs with subs. Very little difference between 1, 2 or 4 subs that I could make out. Maybe the Arendal subs gave a slight increase in depth. Probably a different story listening in room. I will chalk that all up to either your mastery at integrating them into the system or the dreaded youtube compression algorithm.
It could not possibly be my 52 yr old ears with a lifetime of loud music and working with heavy equipment, listening on Bose QC 35 headphones. Your vocals were pristine though. Yay mids!!
Nice video of a beginners guide, but having more than 2 subwoofers on the floor is a waste of energy & money. Next level End Game is SubStacking 👍
Holy crap, double sub approach already sounded amazing. This was super helpful! Looking to add a sub (for two subs). Side question (please forgive but) will we get a comprehensive review of the new NX-Bravos? Curious about how that planar sounds in that configuration 🙏🏼
I still think one sub is better than two
Your videos are best watched at +1.25 speed...
Even the music?
I've caught quite a few bass , they make a really deep thump when they the hit the floor of the boat. And I have treble hooks on all my lures. Used to have a state of the art boat but I sold it and bought something more mid range. When I get my depth sounder facing in exactly the right direction its image opens right up and becomes almost holographic.
I find subs distracting. Give me a well-designed full-range speaker, and I'm happy. There isn't anything musical below 30Hz I'm interested in. Theaters for sound effects, sure.
Agreed. Only if you reeeally can only fit small bookshelf speakers between you and the wall and need to put a sub someplace else it makes sense, or like in case of a 5.1 surround system or soundbar because the spouse hates speakers. If you can fit 2 subs in your room and budget, you can fit 2 full-range speakers in them.
If subs are distracting then they are not set up correctly.
You can tune subs to be seamlessly integrated with mains.
Sure many people are good without bass slam. Not me or many others. Most small medium size towers can’t play 30-40 HZ with authority.
I like that lower octave to have some guts.
Like you said room size has a lot to do with it. My bedroom system stand mounts have enough bass. My listening room has two 12s ported tuned to 35HZ and most music you don’t know they are on. listening to metal, EDM or rap they come alive. Fully pressurizing the room.
@ That's one way of looking at it. I would say, what's wrong with your full-range speaker that you need a sub? Having said that, if EDM and Rap are your thing, then the body vibrations you get from a sub make perfect sense.
Deep bass adds to the atmosphere and the sense that you can feel the room it was recorded in.
@@kingtubbyleeperry I agree, assuming there is acoustic information in the recording below 30Hz.
I've watched many, many videos on this topic and Ron's brings this to a new level. Thank you for your presentation! I learned a great deal and having the sound clips, presenting as you did were very revealing.
can i borrow randy ?
He can be a real handful.
Dig into your couch cushions, shouldn’t be too hard to finance the KU100. 😵💫
What if you have subs with opposing woofers? Do you face them with one towards the listening position (and the other facing away) or turn the sub 90 degrees so the woofers are pointing sideways from the listening position? Or...is it just a matter of taste (or maybe measurements)?
Damm Ron. Those new stand mounts do sound great. When will you present your baby?
Ah! Thanks man! I hope it should be early in the year! I’m very excited.
I dont have a balance control on my amp. So is it safe to disconnect one set of speaker cables ? If you have disconnected one side, did it cause any problem ?
- At least 2 subs
- Get them OFF the FLOOR!!!
- Preferably at different heights.
Placing a sub is easy; find a local builder's skip and put it in
Not able to open the REW link
Chomping at the bit for Ole Danny boy to reveal those new models you have here......
Happy holidays, Ron! Hope you and the family have a wonderful Christmas and a happy New Year. 🔊🥳🎶🎄💜🎅
“Randy Neuman” 🤣 Not sure I’ve heard his last name before. He just keeps getting more handsome with age….
Thanks, Ron. Another home run of a vid. Appreciate you, man.
Your single sub advice only works because you have an amazing response in your room to begin with !
Anyone with huge peaks and nulls in their room (the other 99.9%) this will only make worse and thus "bad advice".
The single sub can be anywhere that the gives the flattest response period !
I use my little SVS micro 3000 sub to fill in the SBIR dip(s) while still running the main speakers (Arendal 1723 towers) full range.
You totally missed on this point IMHO.
SVS also has one of the best Apps for dialing in the sub phase and EQ.
And while we are on subs, who gives a rats ass about bass below 40Hz ?
Most music has little or no energy there. I was thinking about downloading one of the audio clips and run a spectral analysis.
Would probably have very little below 50hz aside from some subsonic garbage in the 5-20 Hz range.
The last thing I want listening to music is hearing the walls rattle !
A swarm of subs…and then I wake up
unsubbed
Just checked on amazon here in France and they are asking 170 euros for the umik-1 (175 $), so that is a dissapointment and willl have to wait
What this to see what a "normal" room looks like (:
th-cam.com/video/RE6g2IawzSQ/w-d-xo.htmlsi=vJD-Ld3P_4XHpvml&t=365
SVS had that technology years ago.
I can‘t do this to my neighbors … it’s an overall bad idea. But I would really like to have at least 1 sub
You should produce your videos with a little more brevity. Like Andrew Robinson.
