- When I say the best subwoofer under $100, I mean it. For Home theater this is flat to about 22hz. Crazy thing, it actually costs less than $100 and can perform as well as some costing over 4 times as much. Today, I not only will show you the subwoofer, but I will show you how to build the enclosure for the best $100 subwoofer. When complete, this will shake your house and will easily hit those low notes you are missing in your movies and music. Definitely a great budget subwoofer build for your home theater.

I can't hear any of the 20hz through my phone speaker therefore this sub must not work.
Haha! Best comment ever!
by default both google and apple disable sub bass through your phone speakers unless you allow them to collect data from the electricity that charges your phone and you also have to allow them to send you targeted ads on your electricity bill. Enable those two settings and your phone speaker will shake your room.

Did you know phone speakers are weak?

Great to see, I'm not the only one using isobaric subwoofer. I'm using 4 subs with RCF P400 18" woofer in 150L enclosure tuned to 25Hz.
PS keep the distance between the Woofers to a minimum. AWESOME 😲👍👊
So glad I got to see the build, awesome!
Fantastic video! I was in the middle of designing an isobaric sub using the new HE variants of the same driver you are using and I stumbled on this video. You took away all my doubts!
Oh yeah We were just talking about a design using the he on the Forum. toidsdiyaudio.com/community/postid/7148/

How to wire speaker
@@geoffreyantonio5766 click the link. All the info is there
Sometime the least expensivce is also the vest for your application, you know the room , what amp, all the thing many people do not know when buying a pre made sub. Good luck with this idea
The first original maker of this type of speaker system was AWA in Australia in the 1960's. They used 2 x 8inch speakers face to face, and the performance was equal to a Certwin Vega 15inch bass speaker.
I built a box with just 1 of the GRS 12 4he version - down firing. The internal volume came out to 3.85 Cu Ft. Using 4" abs for the port. It sounds great and goes down to around. 18hz. I added a 5/8 inch thick mdf top and did an epoxy pour on it. Turned out beautifully. Looks like a nice coffee table in the corner near the couch (main listening position.
This is great! Thank you!
Back in 90's when home theater subs only came with 100 watt amplifiers I went down to a local car audio shop and picked a 12 inch orion in a 4th order sub box with external amplifier and Omg bass for my home theater was insane. I now own 4 definitive super cubes best bass ever.... 🔊
I liked the downfiring table, nice video!
I like your build, exposed subwoofers looks awesome!
Great video. Learned alot.
Great video
It's nice to see some who is willing to think outside the box, pardon the pun cool idea 💡 I have an up firing 6" sub in a tube, it fires into a cross ❌ tube, after seeing what you did, I'm going to fit another sub on top and push pull, but using the cross ❌ tube idea 💡.
I too share the love for the low lows
I have one of the 8" version of those subwoofers. For the $20 its really great. Now that I know I like them I think Ill buy another and one of their high output ones. Then put the 2 normal 8" into my wife's speaker cabinet. It just has cheap Zenith paper cones from the 70's right now.
Killer build! Loved the intro
Thanks man! I appreciate that!
Sweet video!
That's cool. I like to use their GRS12SW for cheap sub builds. Just a few dollars more for the 12" version and needs a smaller cabinet. But It's not anything like my Dayton DCS450. I have it in a sealed box with the Dayton DSP-LF and it is so clean and sensitive for movies.
Excellent idea!!!
Another awesome build and video Nick! I might need to go out on a spend soon! 😁
Only thing is, might want to be careful with these though, the power rating is for thermal performance only, and xmax is quite easy to reach, so go easy with them!
So I used these GRS speakers in some enclosures that I designed with the help of WinISD and this video--2 enclosures of 7 cu ft each. They're big but my gosh, it's incredible. It makes my home theater sound like the movie theater. My wife said tonight, "why do you need it to shake the whole house?" and that confirmed that I had made the right choice. My first sub build and it was a huge success. Thanks for the inspiration!
That is awesome! Thanks for sharing! If you're up to it, we would love to see some of the pictures. Throw some up on the forum. Or even a quick video. I would love to see it. toidsdiyaudio.com/forums/
@@Toid Will do!
Awesome Video! Isobaric loading can be very interesting for some drivers!
Yeah, I definitely wouldn't want to do it with some crazy expensive drivers, but it works for this.
I shook my front metal door with just one 8” sub at 18Hz.
I placed it in a PVC tube about 96” long and 4” diameter. That’s all it took. Simple, light, loud, efficient.
How does an 8 inch speaker fit a 4 inch tube? I'd like to build that.
@@kleinstruction874
You need an 8" diameter PVC or Cardboard tube, then adapt it to fit the 4" tube.
I'm very intrigued. Which specific 8" driver are we talking? This sounds like an interesting experiment
@@sule_imani
Could be any high powered 8”.
The one I used was Massive Audio Hippo
@@Bassotronics Do you happen to know how low of a frequency it can do? I can't seem to find a sub that can hit down to 20 Hz. I'm wanting to build this for my van. A long tube enclosure would be perfect for what I want to do.
I like these odd ideas and low bass!
I recently build a sub that hits 14 Hz with only 1 10" driver. OK, it's a little more expensive, but not too much. I used a Seas L26ROY with a 4 m long folded transmission line in a 2 m tall tower.
Just a little bit more expensive 😂 Sounds like an awesome build!
5:18 no it really looks like the face of
"HOLY SHIT 20HZ BASS!!!" OoO
Another nice proj Toid.
That Bass is what I give my neighbors, sundown audio x18 and 4000 watts driving by slow and loud LOL 🤤 gotta love it
I love isobaric subwoofers
This is great
These subs are 2x the price now, glad you were able to get a good deal!
Have (4) of these 10 in grs in my car for the last 3 years. They sound great. Run the grs 6.5 (2) per front door also sound great for the price
this should get 2 million views
Thanks Again....Carry on Toids.
I’m building 2) 3cuft sealed boxes with 2 JBL 2226h in each box mounted face to face. The drivers were sourced on EBay and Reverb.
The last isobaric subwoofer I built went down to seismic frequencies.
Amar Bose had this design in the Bose 701 . It's brilliant.
Thanks for this video, it highly reminds me of a idea i had.... : -)
I build my own subwoofer years ago which is a isobaric single reflex type with 2x 10" speakers and a build in amp, it serves as a side table and weighs in at 55 Kg (121 Pounds)
The subwoofer manages to put out just a notch under 30Hz, it still makes for some unexpected moments when a low frequency sound effect in a movie kicks in.
Cool video! For the price I have always wanted to play around with those GRS subs but I had already invested in 4x 15", so I'm set. Will you post frequency response measurements so we can see how they actually perform?
I have a Bag End setup in my home theater. A pair of Dual 18" with their ELF1 processor. These subs are 4 ohm. I drive these with a Krell FPB600, which easily makes 1800 watts a channel at 4 ohms. This setup will go to 8Hz. But its a little more than $100.
I had 4 of these in a car in a 5cu.ft. box on 500 watts rms and they sounded nice but they were pretty quiet, one 600 watt audiopipe 12 in a 2.5 cu.ft. box was louder and the audiopipe was $65 vs the grs at $80 and the 12 hit the lows way better but the grs are great if you aren't going for volume
Nice work! Looks like the subs will stay relatively cool drawing just 62.5 watts each. If you want a smaller box you can add mass to the cones at the expense of sensitivity.
I found out long ago that you can have 2 out of 3 of the following but not all 3 at once. Efficiency, low frequency extension and small enclosure size.
i'd give up a little bit of the lows and tune it to 28-34 hz so I could get 1.5-2.5 cubes instead
Nice!
I looked at these a while back and though they seemed to go pretty deep, the box size just was way too big for 1 driver, as you said. Using 4 in an isobaric/compound combination really made it easy to place design back to being able to model on just 1 driver, albeit with much more power handling.
Hmm.
Maybe I'll revisit them and see what they can do in a bandpass configuration...
Also, you could get some nice gloss black paint and detail the bare backsides of those outside drivers. Your own artistic ability is the only limit.
Bandpass doesn't model well, at least with my old calculator. Too high of a Qts.
But the quick calcs show that optimum ported box should have a Fb of just over 24 Hz and an F3 of 17 Hz. Interesting.
@@TheTrueVoiceOfReason yeah I was trying six order bandpass and it really didn't model well. It was basically giving you an f3 in the 60hz range and an f3 in the 28 Hertz range I think. It just really wasn't what I was hoping for
Haven't heard isobaric since my younger days when I studied car stereo relentlessly. Always wanted to do a tube style clear plexiglass isobaric setup.
I Love it,
and clamshell desing also cancel 2nd order distortion making it even cleaner, plus back side of woofer for some reason also has higher Sd, so even more air contact
I have Morel Octwin 5.2 home speakers with the 10" Isobaric loaded subwoofers and I can say these drop cleanly below 20Hz with ease!
I also love the fact that an Isobaric configuration also cuts the distortion level by half at the same frequencies.
Very nice video. For those who may be more cosmetically oriented, as you mentioned and may not like the look, these could easily be compound loaded with the usual cone facing outward design. In this case the second woofer behind will be facing the same direction and it's cone spaced just far enough behind the magnet of the first one. The cardboard coupling chamber can be made using heavy duty concrete pour tubes cut into rings and wood glued between the same facing woofers. Of course, in this case the woofers will be wired together in phase.
Cool I'm goin to mod your box plans to fit in the trunk of my car that should be interesting
Those GSR speakers are a good bargain I have the 6 1/2 to play around with and to replace some JBL bookshelf speakers. They are actually a decent replacement speaker and sound good, another good budget subwoofer if you wanna spend a little more and concerned about space are the Skar audio evl65. I have a pair of these in a box I built tuned to 28hz and they are very impressive, I also have a pair of the rockville 6.5 subs to not as good as the Skar but also impressive.
Power to the mighty woofer.
i recently made a new enclosure for my old z2300 sub (only used the sub for a few years) and well, F3 of the original was 56Hz, new F3 is 27, it's incredible what you can do with existing speakers and 30€ for mdf gets you
I have a working Z2300. One of the best ever. It sits collecting dust now. Congrats on your refresh.
Low low bass is great. I'd love more of the builds on some DIY channels to be about producing the best sound quality not loudest and lowest.
Would have likes to see some bassy music pumping thru those. Also maybe a shot of the windows shaking tooo. Great build otherwise perfect for a basshead 🙌🙌🙌🙌👍👍👍👍
Next time try modelling the subs using Basta. Basta can actually account for port losses and power handling to predict a more accurate max SPL response.
Everyone tells me isobaric is an old alignment that's no longer viable or necessary. This shows why it is...space savings! Great build! I may have to build an end table version of one of these for my theater.
Agreed! All alignments are viable, to someone.
Actually it is an old alignment that's no longer viable or necessary, because it's possible to design woofers that perform the same way with just a single conventional driver. But the 10SW-4 are an example of the drivers that used to be common when isobaric alignments were popular, and it works. It shows the main limiting factor of this woofer design is the strength of its motor.
This woofer is available now so the alignment is still viable. Sure you can design a woofer with higher motor strength and cone stiffness that wouldn't require iso but it would be far more expensive. Again, ISO is still 100% viable in the year 2021.
@@jstrahn Perhaps, but consider the cost impact of Isobaric. When you couple two woofers together, that requires you first buy two woofers. And you don't gain any swept volume capability; both woofers are acting on the same piston diameter and can only move it so far. If you can design one woofer (or find one off the shelf) to do the same work, while keeping it slightly less expensive than 2x the cost of the cheap woofer, then you've already come out ahead.
@@Acoustic_Theory So show me the 10" sub for $40 that matches this. That can play as low with as much output in the same amount of space. The last point being the key. It is viable because it brings the space requirement down to a manageable level.
Liked instantly... I have been waiting for a subwoofer video! I am still looking for a reply about the RV Theater room.
Great build! I wonder what the distortion levels are like though. I am sure with the ISO config, it helps but those drivers can't be very good to begin with.
I built two enclosures with 4 Skar Audio IX-10 D2 10" 400 each. powered by Crown XLS 2002. that's eight subs at 4 ohms. This is one outstanding sub. I have tuned in at 24hz. and frankly, I have unlimited power. since I own a brand new Yamaha RX-A6A with independent sub-outputs. I have every 4 subs on one side. spending $2000 -$ 4000 on a retail sub is insane.
there is a company called stereo integrity. they make the best subs I ever heard,
I love love love the box design. Is there a chance you might make a hardier isobaric box design using a beefier sub?
Cool..! Now let's see an (isobaric) T-Line enclosure built...😁
I enjoyed this video Toid. I just bought a set of inexpensive subwoofers. the GRS 10SW-4HE. They are currently about $55 each Of course the QES is much lower as it has a much stronger motor and 11mm Xmax vs 8.5 compared to the ones you used in your video. They model very well in WinISD. I suspect they may not of been available at the time you built your project. I was going to build them with a ported enclosure but now decided to just go with a sealed design. I figure with room gain I should be just fine; but now wish I had bought the 12SW-4HE's they work in the same size box but handle about double the power before XMax is an issue. I have done that a lot. Buy drivers only to change my mind for a different pair before I even start to build the enclosure.
Some of the GRS subs are staggering good for the price point.
Damn Toid! You were INSPIRED! What did you smoke? Gimme more.
HAHA!
Ok it's been a year... They still kicking ass😁
They are.
Would you be able to make a box that fits in the floor joists. I’ve always wanted to try it.
Love to see more winisd videos
Antônio from Brazil. Nice job changing 0,9 QTS cheap drive to a 0,45 Qts nice subwoofer.
In '94 i ran 4 15" orion xtr duals in a clam shell design n powered them with a earthquake p4300 4 channel amp. I cdnt keep my car together
Great, another project to add to my list....LOL.
This is actually going to be in a subwoofer shootout video coming out
An isobaric set up generally helps with sound quality.
Given two subwoofers, would switching the phase and driver direction within and between the cabinets usefully reduce mechanically induced distortion? This might be beneficial at extreme excursions though whether the ear is sensitive to it or not is another issue. Great channel! Thanks for another great video!
Isobaric already significantly reduces mech distortion as long as you don’t exceed mechanical xmax
Nice budget! May I suggest painting "eyes" on the rear of the woofers.
MMM...I Like ! Would like to play around with other enclosures. (ISO H frame.) What software would you recommend? I get the Theile -Small parameters from GRS ? Thanks!
This gives me crazy ideas to make subsonic noise😁 A tapped Horn with subs in an isobaric setup tuned to 11hz I wonder what driver's to use tho...🤔
Use some Skar SDR-18's
@@potatojake197 Yea maybe... Gonna simulate that tommorow morning in hornresp. I probably have to go for isobaric loading no matter wich driver's as i don't have much room.
@@kaedeschulz5422 If you don't have a lot of room maybe an 18" isn't a good option lol
I use cerwin vega cva121 im in loveeee in this 21 inch booofer if i find another one in good price will buy
This is also a good opportunity to use those cheap 4x100 amplifier boards. You have 4x4ohm loads to work with.
Is there any chuffing at high volume? I’m loving your videos BTW!
Some upgrades to the Dinas would be amazing!
Living in a small apartment, large builds tend to become a bit out of reach 😕
I N .... yeah, the other problem is trying to use it without the neighbor banging on the ceiling with a broom stick. (turn that !@#$ down!)
I'm a believer. Isobaric loading, should be used more often.
Definitely should not be ignored.
I have a great next build for ya. A power supply / preamp for semiconductor (strain gauge) phonograph cartridges. Especially something that is perfect for Panasonic epc-4XX series of cartridges such as epc-451. From my understanding it be done with a simple circuit that can be relatively inexpensive.
Thinking about doing this with one pair in 1 cuft with a 12" passive, for a cheap space saver for my sedan. Just got to figure out what radiator..
All parts, out the door, with the Dayton SPA 250, extra speaker wire etc. is actually closer to $400. That being said, I am nearly done with this build and couldn't be more excited! P..S. this sub/box is much bigger than you think
Sweet! Can't wait to see the final project!
There speakers that have good flex and super loud
If this could tune flat to 20Hz this would be a good sub to downsize from my Ultimax 18 and save space. But I'd have to look for myself when I get home how it does vs the Ultimax 12 in considering.
Nice!!! I have a very difficult question that i haven't find on google,... on a Woofer for a concert, like nexo, D&B Audiotechnik, HK audio, ETC, wich is the correct HZ tunning on a vented enclosure... Those brands, which are the Correct HZ tunned??? I have an 18+ Sound 18" inch 2000 Watt
I have two of the high excursion GRS 12's being driving by that Icepower amp project you talked me into. The bass was so unreal in my media room that I had to relocate the thing to my garage because even my teenage kids were compaining that pictures were rattling on the walls upstairs. So i sit here with them belching some Weeknd (and related) for the appreciative neighbors. They were 60 bucks a piece and I tossed them in 1.25 ft3 sealed boxes. They are comically strong. Almost embarrassing. Almost.
Haha, that is awesome. I haven't had any experience with those ones yet, but I've heard good things. Sometimes it's just amazing what you can DIY for the price. Sounds like you found the perfect sweet spot for that.
Dude I got 8 6.5 on the yung 300 big box tuned to 50 it's insane
Hi , my question bellow but at first: congrats and respect !!!! And a lot of Thank You for your interesting com. So: I prefere using sealed boxes for the low freq with the idea of "pressure" because for mid and Hi, I'm trying to demonstrate that there are huge advantages in HiFi to use the "plan baffle" - the speaker works better and mostely: it is a bipolar radiation and doesn't radiate sideways, on the walls etc. Using already a 4 subs per cabinet (6 and a quater inch), I'm now used to 20 Hz and want to reach 14 :) -that signal is so rare that You would think it is "triggered". Do You have any Idea for what should be the sealed box volume for 4 Isobaric GRS10SW4 - and in a sealed box, there is no Hi-Pass natural filter as the vented does cut off the bottom preventing tne sp from breaking. Thanks very much, pics on demand !!
I got 4 sundown 18's I'm thinking about ripping out and replacing them with these.
How about an isobaric mini sub like a 4" or 6" for a desktop system...even if it's passive. With drivers that size they could be enclosed.
Anyway to do this sealed or is the sound quality of the ported good? Want nice, tight, controlled bass.
I have crown xls 1502 2pcs . I want to build reference series 8-10 inc subwoofer for music . What brand sub speaker do you particularly recommend for my project ?
So we want to build a "portable" box to make some raves outside. Are these suitable energy consumption wise?
How is the sound quality compared to the PN395-8 build?
I'm enjoying all these new projects you have going on!
Thanks Scott. The 15" is pretty awesome as it stays pretty quiet unless you really crank it up. This one is a little noisier, but it handles ultra low frequency scenes like the beginning of Edge of Tommorow surprisingly well. In fact I can run the sub gain all the way up, play the beginning of this movie at reference level in these subwoofers handle it just fine. That is a really hard feat to do. That's a scene that has killed many subwoofers. So if you're looking for ultra low frequencies, I would choose this one. If you're going more for just the bass feeling and not really hearing it, I do the 15-in, and keep the subwoofer amp gain about halfway.
I'm actually sitting about 5 feet from a ported 18" cabinet that's almost exactly 6 cubic feet after accounting for driver and structural volumes :D tuned to approximately 27 Hz but it's for my bass guitar so that's plenty low, I had to downtune my 5-string 2 full steps to hit that low G at 24.50 Hz, and considering going lower since it's still quite loud and tonal. Might even go all the way to E0 (20.60Hz) on my B0 string since there's still enough SPL to hurt your unprotected ears
I have 2 4ohm dvc 15s with a total rms range of 200w-800w what would be a good reasonably priced plate amplifier for them?
I put 16 GRS-10SW-4s in 30 cubic foot wall tuned to 22hz on a Audiopipe APNK4001.
Dang!
What did you do to get WinISD to play nice with the specs of the driver? No matter what I do, it throws integrity errors and gives really odd graphs, other tools seem to have integrity issues as well. I was curious about comparing the standard variant to the high excursion variant, I was also curious about comparisons of the 8s, 12s, and 15s in both lines.
Can you make manipulated vortex waveguide bass guitar cabinet ? 1x8 or 1x10
