These numbers have always referred to the amount of dedicated audio track channels. Unfortunately, bad marketing and the spread of incorrect information across the internet have made it harder to understand, now more than ever... Great video by the way, keep spreading the knowledge! 😉👍
Once had a argument with a BestBuy employee claiming they had an 11.1 (or some other ridiculous #, before Atmos was a thing, mind you) sound bar because it had 11 drivers... 🤦♂️🤦♂️🤦♂️ I had to LOL and walk away.
Great video Michael. I agree with your assessment. I think people like to refer to the .2 so people know how many subs they have. I personally do but wonder as multiple LFE channels become more common over time if we will be forced to use correct terminology.
Does adding a MiniDSP to a system upgrade it to a multisub system? :P
@@BradleyAshley Nope, while it does allow you separate EQ for each sub, all of the subs off the MiniDSP are still receiving the same signal.
Awesome video! Thanks for looking into it! Completely makes sense! Felt cool to be on the video!! Haha you were right! I guess I have to wait and see if my amp gets an update for dts x pro!
Thank you for the great discussion on it.
Yes you are correct in this explanation. But as everyone knows when someone says they have a 7.2.4 or any other configuration, the .1 or .2 we are saying how many subs we have. At least that’s what I have always meant.
That's how I have always thought of it. I just assume that's the number of subs they are using on that .1 channel.
@@VitalYFZ glad I'm not the only one thinking it!
Hey youthman you’re awesome keep doing you ! Also I have a 5.1.2 atmos setup
Appreciate the kind words
Hi Youthman, I am just about to go for a true 7.2.4 atmos.
The projector will be the JVC-NX9 8k & the AV will be the Marantz SR8015 (which is not yet available in Australia)
And the screen will be a 16:9 160" screen, the projector & Amp are the only three items locked in. (Ceiling height for the media room is 3m so a 140" screen may fit better). I was thinking Klipsch for the speakers in a setup similar yours; the behind the screen horns with other complimetary in wall speakers with Corner L & R front Subs. I would also love to see your recommendations for an all in wall set up using klipsch speakers. I'm not sure on the behind screen set up as my room is 5.6 metres long by 5.5 metres wide. There are so many in wall options, pro reference, reference THX ultra 2??? So confusing🤯🤯🤯
@youthman - thanks for the info. I find it interesting as the Yamaha 3080 processes the 2x LFE outs as “mirror”, or left and right, or front and rear. I always assumed it was reading that data from the single LFE track and that the single LFE track was carrying an “atmos like” layer that provided “LRFB”’data. When running atmos tracks and the LFE set to front /back, LFE effects are distinctly shifting based on source of action. I guess that means some sort of DSP in the Yamaha is doing some cool work to make that happen. I really appreciate the breakdown, the more we understand about our setups the more we can optimize and enhance our sound. Great vid.
Thanks Adam, glad you enjoyed the video
Pioneer Elite SC-75 9.2 powering (7.2 setup) NHT Classic Four Tower (bi-amped), NHT ThreeC Center Channel, NHT 12" + NHT 10" subs with 4 - iC4-ARC 2-way 8 inch ceiling speakers.
Appreciate what your doing.
Per your explanation, I now have a 7.1.2 system 😁
feels bad, right? I hope the home theater community can find a simple way to describe our setups and still be accurate
I think the confusion is there is a difference between format and configuration.
7.1.2 is your format but your configuration might be a 7.4.2
@@Youthman that’s a fair way to explain it. I like it 👍
7.1.4 speaker setup for me. And yep, I've known movies have always been mixed with 1 LFE channel (and home receivers have been marketed as .2 for having some independent level control). IMO a new spec for separate LFE with DTS:X pro won't be that clear an advantage, since sub-bass has less localization (and the whole reason for a "subwoofer crawl" is finding the sweet spot where your subwoofer(s) fill the room). I'm also not sure how pervasive DTS:X pro will be as Dolby has really made inroads with being the popular 4K format (with Dolby Vision and Atmos....there's still a tiny amount of UHD discs that are IMAX Enhanced for example).
Also, when it comes to these new 3D audio formats: they're meant to be backwards compatible with old standards (that was an array of speakers with 5.1 channels). Now an audio engineer mixes a "bed" that's 10 channels (up to 7.1.2), and then there are 118 meta-data tracks for audio objects (which can then localize a sound from this bed to any seperate speaker config that's in the particular theater).
Hey Youthman. Joined the Youthman Crew on FB recently. My first home theater I built is currently 5.1.2.
Awesome! Welcome to the group.
And congrats on your first home theater build! That’s awesome Derek.
5.1.2 / 7.1, depending on if I'm listening to ATMOS/DTS-X my receiver uses the 5.1.2 "height channels" as the .2. With regular DOLBY and DTS it runs 7.1 utilizing the back surround speakers.
Awesome information because I was racking my brain trying to choose a new amp without breaking the bank because everything was saying 7.1.4 and I know I can’t live with just 1 subwoofer, I need 2 subwoofers! Now that you cleared this up for me, I can rest at ease and go pick up my new DEON! Thanks Again, Great Content!
Glad to help. Yes you can connect multiple subwoofers even to a single sub out using a Y splitter with no problem
You are correct, I just didn’t know if I would lose left and right channel separation in my subs. Right now I have an Onkyo 11.2 channel, but it’s not atmos. After watch this video, I can now have the desire atmos sound I was hoping for!
Mine is 5.2.2, all B&W powered by a Denon AVR-X4500h.
7.2.4 (I know where this is going :)
Hahaha
Let me know after you watch the video
Youthman I watched it all. Just commented again :)
7.1.4 but now when I eventually get a second subwoofer I won't be able to call it a 7.2.4
Haha , I hear ya !
5.1 existing of fronts: Klipsch RP-8000f, center of Klipsch 504C, surround B&W M1 and my sub is B&W ASW2500. Actually the Klipsch are not able to sound as they could because of the very small area they are placed in (my bad)
Don’t know if I fully agree with this. It’s semantics. It is a single channel of information, but the naming system is to signify how many speakers you’re using. If you have four subs and five ear level speakers in a system, it is a 5.4 system. There is no need to specify .1 because it could only ever be .1 - it’s implied that it’s receiving only one LFE channel of discreet information.
For my part, I will call my system by it’s true number of speakers; 5.2
L&R: KEF R11
C: KEF R2c
SL&SR: KEF R3
Sub: KEF Kube 12b x 2

Call it semantics but I have yet to see Dolby label it that way. I totally get it (and sometimes refer to my setup as a 7.2.4) but it still isn’t correct.
Does Dolby offer setup guides for multiple subwoofers? I’ve only ever seen their setup graphics with a single sub. I mean to say, that they may not specify that because as you accurately stated the SIGNAL is processed as 5.1. Therefore, when someone is describing their system - no matter if it’s 5 speakers and 1 sub or 5 speakers and 10 subs - it will always behave as a 5.1. You are correct.
However, as you and I tell each other about our systems, I can’t see myself describing my system any other way than it’s literal layout; 5 speakers and 2 subs, or 5.2.
I am happy though that you are educating the masses on the .1 channel though. Many people don’t realize that it is completely discrete information not ever played through the other channels.
Keep up the good work!
Thanks Nicholas. Honestly it makes more sense to refer to it as a 7.2.4 vs a 7.1.4 with dual subs. 🤣
Processing and Channel Layout could be described in two different t ways.
.1 is the channel information on the disc.
Only one channel.... so 1...not .2
Wireiing my home theater for 9.2.4 or based on what you explain in this video 9.1.4
Marantz 5013 7.1 with two subs and 60’ 4K tv 📺 . The police 👮♀️ came only once so I am good
Well, then I will describe my system as a 7.1.4 because that is the signal that I’m feeding it but if I‘m talking only about speakers I call it a 7.2.4 setup and with DTS:X Pro the content then will also become 7.2.4 then. But I think at times it will happen that I use those descriptions incorrectly because it‘s either not relevant and easier to describe it that way or just because I forget about it. Thanks for clarifying though!
so for 400 aud which is about 300 ish US i picked up an anthem mrx 700 for dolby true hd, i cant do ceiling channels so im stuck with 7 channel through the anthem. i cant think of a use case in a living room where you would need anything approaching more. its really amazing what you can get now for a fraction of what it costs if you look around for 'grail' receivers from the late dolby true hd era. also most stuff has never hit 4k blu ray and there is only so many times you can watch transformers to show off your receiver so i recommend you build based on what you watch.
so in theory if you have more than one subwoofer the signal is being shared which makes it weak thus making no sense of having more than rather a single powerful sub.
Good man, love how you humbly approached this. Much respect.
But I don't think the question wasn't answered. There can only be one standardized definition for the ".2" nomenclature. However, you said the AVR nomenclature refers to quantity of processed sub outputs (still from a single content source), while the content/Dolby nomenclature refers to the number of discrete content channels (independent of sub outputs). So which contradicting nomenclature is the official standardized definition? There should be verbiage/proof in the standards spec (AES?).
The proper expression is 7.1.4, 9.1.6 etc, as those numbers do refer to the channel outputs. People sometimes use 7.2.4, 9.4.6 as it is easier to describe how many speakers and subs you have. This isn’t proper, but it is certainly common.
I'd love to see the new receivers start adding multiple subwoofer outputs that are discrete frequencies. That way we could use like, a 10", a 12", a 15" and an 18" sub all with their own outputs to have loud bass at all frequencies.
That sounds like a nightmare to set up and prevent room nodes/nulls everywhere! I know you mean each sub would cover its most suited frequencies, but positioning would still be critical.
Always a pleasure to watch youthman.
Youthman (and subscribers), I want to humbly add my thoughts on the LFE debate. The dual LFE outputs on receivers that are independent is for when your setup has either different subwoofers, or uneven placement (one might be corner loaded unlike the other).
I used to operate a mobile disco / p.a. in the nineties and found out (in our last year of playing) that placing the subwoofers together, in the middle of the dance area (it was huge passive speakers) gave the best bass!
Unfortunately not many people can place subwoofers in the middle of the room.
So now you are saying i have to upgrade my receiver......man i wish it could be done via software update
If that’s a serious comment, you do not have to upgrade anything. You’re fine
LFE is only 1 channel and you can have as many subwoofers as you want. They will all play the same full LFE signal.
I agree. The purpose is not to convince anyone they need DTS:X PRO, the purpose is to correct misinformation
Ha, i didn't know DTS:X pro has 2 different LFE channels. I also wonder (like you) what will the setup look like in order to work.
Also do you know if there are any DTS:X Pro mixes that can be bought yet?
I have a 7.1.4, got a Marantz SR7010 "no need to upgrade yet" and a Emotive BSX 700 for the surrounds, ,and my sub is a SVS SB13 Ultra.
All this time I thought. 1 was the # of subs🤔 thanks for the info youthman.
Ok I got one for you. If I have 6 floor level speakers , 4 ceiling speakers and the LFE channel. Is this 6.1.4 or is it technical a 7.1.4 because the data is 7 channels but then processed to 1 SB speaker?
6.1.4
Think of the first number as how many directional speakers you have in front of u, to the sides of u, and behind u
The second number is always .1 since it’s 1 LFE channel
The third number is how many speakers you have above you for atmos.
Hope that clears it up
Hi Youthman, great channel and very informative 👍 👏 👌 I always had a 5.1.2 setup because I had the onkyo TX-NR676 which is a 7.1 Channel receiver. I recently got the Denon 4500h and would like to add a extra pair of heights which will give me a 5.1.4 setup.. I would like to know would that extra 2 in ceiling speakers make a huge difference in my setup? Thanks in advance

I think your monster subs count as like 4 subs per housing. So you have a 7.10.4 setup 😀

Very interesting! I did not know this about the LFE channel. I am currently rocking a Dolby Atmos setup, 7.1.2, with dual subs LOL. (7.2.2)
Is there any DTSX Pro program material out there? It makes no sense having 2 LFE channels in the receiver if there is only one LFE source. I have 3 subwoofers, each of which receives a different mix of LFE and other channels and is independently EQ'd. But that does not meet the criterion for .2 or .3. Neither, then, would a genuine DTSX Pro receiver when playing a single channel LFE source.

Hi Youthman I have 5.2.2 or 5.1.2 (with this new info) thanks man great video as per usual
Great explanation for all of this. It is kind of confusing, especially when you start getting the receivers or mini DSP's to start tuning multiple subs separately. But I agree, it's all one LFE signal, just different time alignment and tuning in most cases
Hi Ajitman.. wanna know more about JBL HDI speaker series ... specially it’s centre channel JBL HDI 4500 performance ... pls guide on same about its performance vs it’s price
Rajiv K chauhan
That is NONSENSE. If the 1 just means the one LFE channel then we would just remove it and say I got a 5.4 for 5 speakers and 4 height speakers. I have a 5.3.4 and ANYONE can understand that means 5 main speakers, 3 subwoofers and 4 height speakers
I like how this video is like sitting next to you having a conversation talking about it and not just telling us keep them coming youthman 👌
I do have a 2.2 set up, yes 2.2. Subs are run hi powered individually to each monoblock. Yes I have a home theater thats 7.2.2 which is really 7.1.2
For your record: I run a simple 5.1 system, mainly also because of the Wife Acceptance Factor. On your stand on what the numbers mean, I do have to give my 5 cents. For me there always have been two separate tracks involved. One is talking hardware, one is talking sound. As such to me an amp which has a handful of regular amp channels and 2 sub channels, which can individually set, will give me the opportunity to have a 9.2.4 setup. That just tells me how many speakers I can cram into my room. Than there are the sound standards, which are supported by my amp. I fully understand that there is only one LFE channel there, so my two subwoofers will deliver the same sounds. One of your older video's shows that it has advantages to have two subwoofers, so they will help eachother bringing more punch to my system. But that again is a hardware thing and has no impact on how many sound channels there are in my soundsource. I agree with you that I want to see what it really means if on the sound side there will be two true sound channels for LFE content.
you are mistakenly confusing channel processing and speaker configuration.
speaker configuration I have 7.2.4 but channels processing will be 7.1.4 ... but these are separate things.
Very interesting. But does make sense.
7.2.4 marantz sr7013 and mm7055, bowers and wilkins front stage with 702 s2 and htm71, 686 s2 and martin logan atmos speakers and polk surround speakers and 2 subs. love ya videos mate, thanks heaps.
HI there. What you don’t say clearly and is the important thing that the AVR is processing the audio from your film. This audio stream CONTAINS ONLY ONE LFE CHANNEL! It’s that easy to explain
I thought that was made clear when I said the only format that has more than one LFE channel is DTS:X Pro.
I figured out what's happening. Channels is the # of speakers, which is why the AVR companies list the sub outs as .2, however Phill Jones is saying that there is only one LFE signal in current home theater audio codecs, regardless of the # of sub outs. Youthman keeps saying "channels" when he means to say "signal". Hope this helps.
I have a 5.2.4
I will have to kindly disagree with you Youth Man and I'll explain my position.
My Denon has 2 Sub Outputs and I can put in Audyssey if I have "O", "1" or "2" Sub's which I know you know that.
In the settings the Sub's can be adjusted separately for distance and volume output just like any other speaker in the setup.
In your perspective if the "LFE" will always be ".1" even the are 2 separate Sub's working differently depending on the sound source and sound travel direction then a set up like mine as of 5.2.4 should actually be 1.1.1.1.1.1.1.1.1.1 because by your definition the 2 Sub's are being treated as 1 Sub only.
I hope I didn't confuse you.
I havea 7.1 but my klipsch 10 inch sub keeps poping it is hooked up to a Onkyo avcan you help.
Does anyone really think separate bass/LFE channels is a good idea?
Doesn’t make sense to have more than 1 dedicated subwoofer/LFE channel.
You should be able to get all the LFE frequencies that are there with only 1 subwoofer.
You shouldn’t need 1 subwoofer to play from 120hz down to 35hz and another subwoofer to play from 35hz down
Makes absolutely no sense to go down that road IMO
Have 5.1 on klipsch speakers and pioneer receiver. Have a question I play you tube music sub don't work only 2 fronts so I bought a splitter for left and right cable plug it in play you tube music no sub bass only front.
Just started watching but I always say .1 cuz there is only 1 LFE channel.
People just like to be clear and state how many subwoofers they have.
The LFE channel is only 1 dedicated channel. Anyone who says otherwise doesn’t understand LFE.
2 subwoofers, 4,6,8 it doesn’t matter how many you use. They ALL get the SAME LFE signal.
There are not separate bass frequencies being sent to subwoofer 1 and another separate LFE signal being sent to subwoofer 2 etc
It’s all the same signal.
If you have 2 sub inputs, that doesn’t mean you need to use both inputs to get all of the LFE information that is assigned to the LFE channel. Both inputs receive a full LFE signal, not only certain frequencies.
There is no need to have more than 1 LFE track since bass frequencies are omnidirectional. This is why you can put the subwoofer wherever it sounds best in your room.
This is different from you’re center channel for example. This is a specific channel that needs to be placed in the front of the room and the dialogue etc is specifically assigned to it.
You simply can’t do that with bass frequencies. I’m surprised there is confusion to this but nice video to clear this up.
I need to watch some Trinnov Webcasts about the DTS-X Pro feature with 2 separate sub channels. Really curious why that would be implemented.
7.4.4. My pioneer elite vsclx-504 only recognize ls a 7.1.4 in its setup even though it has 2 independent sub preouts. !
I think you will find the video rather enlightening
Your setup is coming is coming along so nice!
Youthman I did. It was a great video. I’m
About to upgrade to a new denon.
@@myhometheater7029 What do you plan to upgrade to? I'm looking to upgrade as well from my current Sony AVR
Matt Ording sorry I just saw this. I’m thinking the denon x6700h
First time posting love the channel! Running 7.1.2 👍
My system is Onkyo TX-Nr696 7.2 THX Dolby Atmos with 2 subwoofer outputs. It's only connected to the Subwoofer (No Speakers) but using Vizio M51 Soundbar to the TV for Dolby Atmos. LFE will always be at 120 HZ, thanks for explaining that to me. The subwoofer plays very good when it was 80 HZ but some subwoofers will malfunction or sound bad if LFE on receiver crossover is Below 120. I also used the dual RCA filtered connection, using Subwoofer crossover at 40 to 50 HZ that was hitting deeper harder bass, got violent. Now i will set Onkyo to LFE Off and Sub crossover at 50 HZ (it can't be turned off)
7.1 here. Our ‘standard’ UK houses are kinda to small for most people to have a dedicated room, don’t get me wrong, lots of people have dedicated rooms over here, but mine is in my living room, anyways, the Audyssey does a very good job of fixing my crazy room layout, I don’t have room for side speakers as there are doors in the way or the rears would be maybe 2 feet in front of one another. So I have dipoles from Mission for my rear surrounds and surround backs, unfortunately I have to have them all behind me on my back wall, the rear surrounds are up about 5 feet above my head, the surrounds are at ear level, as they are dipoles they do a great job along with Audyssey of creating that all immersive sound, one day when I have a dedicated room I will fix this as my sons room (for now) is ideal, well better than what I have now lol, as you say YM, it’s how we like it and how the set up runs and corrects it, keep up the amazing info and stay safe
I’m running 9.2 all Martin Logan electrostats and 4 Sb16 ultra subs that are dual stacked front right and left rear. I have 2 LFE out channel on my processor that can be independently adjust but the LFE signal is a .1 mono signal audio mix that is sent to the subs.
Technical I have a 5.1.2 setup but am running dual subwoofers. I found anything beyond that got me some diminishing returns.
I still have a 90s Onkyo and a 6.1 set up with Dolby pro logic IIX and DTS neo 6 cinema
I guess I'm still old school... I'm running a 7.1 system, Yamaha Aventage RX-A800, 6 Dayton Audio MK402X's and a Dayton Audio MK442 center channel, with an SVS PB1000 sub.
Nothing old school about it. That’s a great setup
Yes Technically correct.Have heard this before in some forums. But nowadays ,As some people want to show of their system and layouts they stick on to x.2.x .
It's all started from AVR manufacturer marketing I believe.
I have a 4.0.4 with two subs crossed with the left and right channels at 80hz. Sending the lfe channel to the mains as full range, so technically i have 2 discreet sub channels but not using the sub out on my preamp. ;) soon to be 5.0.4 need to get a center. 😝
I'm experimenting with 2 Yamaha receivers. I just added an RV-V A6A. The other is an older RX-V 2600 unit. I'm running basically a 16.9.4 system. I use 2 plate amp powered Subs and 3 more subs powered by 2 Carver M400 power amps. There are 3 more self powered subs.in resonance nodes Total potential power is around 2000 watts. I'm just finishing the wiring and there's a buttload of it.
The testing and YAPO self measuring should be interesting to see!
Thank you for explaining in details
The surround field designation (5.1, 7.1, 7.1.4, or 9.1.4) should always pay respect to what's on the print and for object based content, what the Atmos/DTSX renderer spits out. What's handled in the DSP downstream can be any number of things and often leads to confusion. Case in point, If there are 9 LFE subwoofers on a big mixstage with unique delays that doesn't mean the mix is now 5.9. All 9 and still receiving the same input feed.
I am glad I come across this video because this is honestly something I thought about myself. I am using 2 subs and have been for a few years anyway. I have sat and thought albeit there are 2 outputs on my AVR (STR DN1080), when I go into the level settings there is only one SW level in there. Another thing I have thought is I have never ever heard the bass frequencies move from one sub to the other..not that it would be easy to hear if it did. But I am aware it is obviously just the same channel. I also have thought that if the "5." refers to my other speakers as separate channels how can it actually be 5.2?
BTW I am currently using a 5.1.2 set up here. not an actual 5.2.2 :) ....well the sticker is still on my AVR and it actually says its 7.2..... I have suspected for a long time... that isn't accurate. Anyway I need to get myself a 5.4.1 AVR..my room isn't huge but I still think it would be a lot better. I definitely don't have room for surround back because my TV is 65 inch and my couch is almost touching the wall. I don't want to be any closer to my TV than I already am. So I went with the 5.1 and 2 atmos. I had the surround back set up in my previous home as I had the space...but back then atmos didn't exist :) Anyway thumbs up very interesting video.

Hello Everyone!!
There's so many things to cover, and I don't know where to start.
I own a somewhat dated Pioneer Elite VSX-LX301 A/R Receiver, and currently running 5.1.2.
In order for DTX-X Pro to happend, the movie industries have to start recording thier movies in that format now.
Next, those public theaters e.g. AMC/IMAX have to install a second sub, alongwith a power amplifier, plus intergrade the DTX-X Pro feature into thier equipment area.
Furthermore, get a new Blu-ray DVD player to pass through that signal, and have our A/V receiver to actually decode it.
Trust me, that will take some time for us to get there. Personally, I will not worry about that format, because we still even today, have people don't fully mastered the very basic of Dolby Laboratory's speakers placement.
I'm referring to setting the correct speaker size, distance, HPF, and most importantly the calibration setups.
We need to get that done first, before worrying about a new surround format.
In your video, you mentioned two manufacturer receivers that gives a true 5.2.4, or 7.2 or 9.2, but if you don't have neither one, its always 5.1, 7.1, and etc.
Don't let those numbers of rca suberwoofer jacks fool you, because its always summed out as one signal, not two independent signals.
I'm currently rockin a 6.1 system. Boston Acoustic VR1s and SVS Ultra center and surrounds. I love my Harman/Kardon amp and receiver. I am using 3 subwoofers, 2 Polk audio PSW-10s and an SVS PB-2000. I'm just waiting for the Denon AVR-x3700 to be available and then it'll be 7.2.4. Can't wait! I scored some Yamaha in-ceiling speakers with directional tweeters for my Atmos speakers. After that, my next upgrade will be moving from a 65" 4K TV to a 4K projector. I really want something bigger so I'm thinking 150"!
11.2.4 for me.
update to ur info. 11.1. denon avrx-6500
updated after watching. had 11.2.4
What I understood Phil to say was the content, not necessarily the hardware, was the primary limiting factor.
So....I've got a 7.2.4.....but run it as a 9.3.4......rooms 12 x 15......im just getting into 4k projector now they bring out 8k...grrrr...slightly behind the curve...as usual...but i love it!!
Would you need to change your seemingly perfect mini DSP settings for you to get 2 lfe channels for dtsx pro? Isn't it set up with one sub input to two subs
I am certainly no expert when it comes to the miniDSP but it would seem the only way to utilize dual LFE channels would be to use both inputs on the miniDSP but that is only a guess, nothing more
Youthman would you sacrifice your perfect sub chart for stereo subs?
5.1, Paradigm Studios with SVS PB-4000 sub. Rotel pre-amp and amp.
Question: SVS customer service told me to add a splitter to my LFE output and plug both ends into the LFE and line level input of the sub. They said that can add 6db of volume compared to just having one LFE input. Is that unique to SVS, or is that common practice?
I’m running a 5.”2”.4 set up I have all matching Pioneer AJ speakers and I have it anchored with 2 HSU ULS-15 MK2s... they rock my house... interesting thing is that even with DTS:X pro ability to process “stereo bass” it’s kind of silly in the home theater. Let me explain, bass waves are far too large for home theaters to be able to distinguish a true left and right. That’s why things like a mini dsp, to essentially create one cohesive sub through time alignment etc makes far more sense and important. DTS:X pro would only make sense if you had a gigantic room where bass waves weren’t larger than the room themselves.... bass waves can be well over 50 feet long(20 Hz is 56 feet long!), think about that! So this whole .2 nonsense would probably be a bad idea, not to mention the bass cancellation that would probably happen, so I’d argue “mono” bass is the way to go in the home theater especially when paired with a mini dsp.
@Youthman So now everyone needs to say they actually have a for example, 5.1.4 with 2 subs. Instead of 5.2.4. To be politically correct that is.. So this bring up a new problem or idea for everyone. This .1 LFE has many installing 2 subs to help equalize bass and remove null spots. So with the addition of a second dedicated LFE channel presumably pushing different content, the same issue arises. In order to smooth out that bass response and null spots, two more subs will be needed. In other words, DTS:X Pro setups will now benefit more from 4 subs instead of just 2!
Hi youthman, I am going to replace all of my speakers (7.1.4） my target is 40i and 50xti, but i am still consider getting 35xti or FX2 for surround speakers and surround back speakers ? FYI, the width of my room just 3.6m, and 6.5m length. I sit at the middle. hope to hear your valuable opinion.
About the LFE. I'm told that LFE only goes to the left channel of the AVR, at least my Denon does. This is the 2 channel. I have 2 subs connected to 1 and 2, but only LFE will go to 2. So what goes to the 1 channel? Only bass? From 20Hz to 120Hz? My fronts are setup as large with a crossover at 40Hz. They can handle that. So any lower then 40Hz will go to the sub connected to 1?
hi i have a 7.1 system with two subwoofers i intend to purchase an emotiva xpa-2 at some point but right now i am running a Yamaha 3080 with a Bryston 4bst running my L and R I have a Panasonic DP-ub820 as well as a mac mini and a d150 for music. I hope to at some point upgrade my Bryston to a mc452. My system sounded amazing in 2.1 until i tried to incorporate a c2300 using the pass through anyways i will get it figured out and i am not at all impressed with the power my receiver is sending my rears and my svs di/bipoles but then my L and R are 97db efficient and are connected to the bryston
I'm running a 7.1 setup Non-Atmos AVR. Looking for New Denon 8K series (Actually for HDMI 2.1 though). I'm using ancient Denon AVR1909 currently.
What if I send LFE from my AVR to my better 12" sub and split my center speaker-level signal into a weaker dedicated sub to make the center channel nice and meaty? I am 7.1.2 by signal but 7.2.2 by eargasms.
So I’m under the assumption that .2 is just referring to output on the receiver . Yes LFE is only one signal it can be split multiple times to add subs but still one frequency . So when they sell AVR’s as 13.2 it is referring to the two sub outs so yes you do count the amount of speakers you have . You just have to know that lfe is one signal . So I still refer to my system has 5.2.2 . Or am I completely wrong and need more education on this . Good topics youthman makes you 🤔🤔🤔🤔.
I’m new to the theater community. I just brought a Marantz 7015 AVR. Was this a good purchase. I replaced a Onkyo 787 and it sounds totally different.
My set up is a 7.1.4 with klipsch speakers, 2 klipsch subs, a Denon receiver, 2 Emotiva Amps, a power conditioner, 5040ub Epson projector to a acoustic silver ticket screen.
As soon as an AVR has two subwoofer outputs which both receive a different signal, then it is legit to feature it as a .2 (like 7.2) and so forth. An AVR always specifies what it can control, not what the content holds.
If I watch a 5.1 movie and I got a 11.2.4 system, then it is possible for all speakers and subwoofers to output sound.
Just as well if I watch stereo music, the subwoofer will also be included if I have one.
If the AVR is able to generate two independent signals for the subwoofer, this can greatly increase the base accurary for the room. And it does not matter if there is only one LFE signal, two, or if the base comes from the other speakers.
I I'm using a denon x8500ha running as a 9.2.4 which just rocks!
I’ve heard great things about the 8500. Congrats!
5.1.4 setup for me. I am about to go to two sub-woofers and replace my old Paradigm sub. Having some questions with how to set them up since right now the one is wireless, but I have decided to keep the wireless and chain the two new subs since I would have a hard time getting the LFE wire (or wires) to the subs.
Denon 4700 5.1(2subs).4
Emotiva XPA-9
All Klipsch
5.1 dolby digital is cable. Blueray supports many channels. I've took time out of my life to setup a 5.1 system off a 7.1 receiver and when I go to yt, it autos to a logic decode. Great
I have 5.1.2 atmos in overhead config.Yamaha mentions their AVR as 5.1.2 even they have 2 sub output..now I understand why they do..thanks
