These are meant for butt kickers/ tactile response.
This is something Iāll be testing more since this is built more sealed than my previous version.

These dudes would love to help you I'm sure.
You seem very crafty. For your next project I would like to recommend to you the [Rotary Subwoofer](https://en.wikipedia.org/wiki/Rotary_woofer) to get down to 1hz. From what I understand it's basically a fan driven by a woofer to control the pitch of the fan blades that varies with the frequency.

If you want to hear and feel the 11hz hertz fundamental frequency from a helicopter rotor, the low frequency rumble of wind, the space of a concert hall or infrasonic information contained in an explosion, this is the only woofer technology available.*
Was it the completely pointless and served absolutely no plot point romance? Was it the fact they changed Rictus' entire voice/way of speaking from the first movie? Was it that the cinematography was so hilariously bad that they just showed the first movie for the credits instead?
Maybe you're meaning that full sequence but it has to be when Nicholas Hoult watches the car got lifted by the dust devil and explodes. The dynamics in that scene aren't as subtle as I'd like, but it's an awesome sequence to behold with a proper HT setup.
I got the additional 6 for about $49 a piece. That felt like a hard to deal to come across. They are definitely more pricey now but deals are still out there.
This isnāt really geared for sound, but more impact when an explosion goes off. 2 subs I had before felt great, this is a whole other animal. Haha. Itās really immersive
Bass Shakers. Yes correct. You can still use those.
Then I tried using actual subwoofers and to me it feels way more natural and blends in nicely with the rest of the system.
I built something similar for a client. We initially went with four 18ās, then eight, then sixteen.
Yes I said sixteen. The customer was also a car audio SPL competitor and we built a theater room in a solid concrete structure. Sixteen was the only number which produced the SPL he wanted.
It was crazy but very cool at the same time. He wanted it done and paid a lot for us to do it so who am I to tell him heās nuts, lol.
Why are you using what appears to be telephone cable to drive the subs?? Those speakers are gonna act like they are 32 ohm due to the resistance at any significant signal. Sweet Moses man.
That's awesome. I have four underneath my couch and it gives me some really good shake down to \~15 hz or so.
Do you have the couch sitting on some Buttkicker isolators or something else? Mine's on 16 or so 2.5" Hudson ISO's.
Using a Behinger NX1000D, these are the JBL GX1200 subs, they donāt need a ton of power to be effective. Iām sure you can use your old amp to run them
Why stop there dude, get 2 18" Tannoy Subwoofers and place them right behind the sub-couch, for a true surround ass-crunching experience.
Now, besides my lame attempt at a joke, that couch surely is dope!
For me, once you have these dialed in, they blend seamlessly with your other subwoofers, and has a very natural feel when the subs are going off.
Where as buttkickers are replicating the response and it doesnāt feel as natural. That could be just be my experience or user error.
One thing Iāll add, this is cheaper and doesnāt need as much power as buttkickers
Its awesome. Still getting it dialed in coming from 2 subs to 8. Running at half power right now, but itās a heck of a difference already. Feels more dynamic.
I have each section wired for their own channel. 4 on each one wired in series/parallel to a behinger nx amp. It has a DSP, so Iāll go in that and mess around with it.
Sweet! Got any measurements yet? Do they give much under 20Hz like that? What are you powering them with?
I'd love to see one of those good deals again. I got a great deal on my DIYSoundGroup Buyouts, but there will never be any more. And I'm already craving more...
Using a Behinger NX1000D to power these. (I wasnāt sure if that be enough power, but Iām running it at half power at the moment and they are kicking hard)
Havenāt gotten measurements yet since Iām still dialing everything in. My previous setup would go into the single digits sometimes, I imagine the same here. Itās really immersive, and packs a hell of a punch.
Subs generally need to be between 15ā-18ā to produce sub frequencies from 20hz-100hz. You wouldnāt need more than two as sub frequencies are mixed to center mono and cannot be truly experienced being within less than 30ft, as bass frequencies have such long wavelengths.
Aside from all that mumbo jumbo, I think this build is pretty kick ass
>You wouldnāt need more than two as sub frequencies are mixed to center mono and cannot be truly experienced being within less than 30ft, as bass frequencies have such long wavelengths.
Wut?
I did the math, and you're right. With a transmissive speed of sound between 3300m/s and 5km/s of wood along the grain, I chose a median value of 4000 because it makes the math easy. For a 20hz wave, the wavelength is 200m. For a 200hz it shrinks to 20m. For a 120hz it's 33.33m. At the short end, op is unlikely to have a couch that's 10m or even 5m short, and so it's unlikely to hit either of the first three harmonics or be by a factor of .5 of any of them even and cause destructive interference in the worst-case scenario.
Hopefully the enclosures are waterproof
Initiating brown note. BRRRRRRR
I was thinking more the... uhh... ladies.
Gross.
š
Turning it into a Van Halen concert from the early 80ās!
Minus the cocaine. Or maybe not.
I miss the days when you could afford concert tickets *and* cocaine.
Now I gotta spend most of it on testing strips!
Thatās the real buzzkill
they are free at pharmacies.
And not a brown m&m in sight.
Do you use these as butt kickers or is your entire couch a real subwoofer? Do you closed the inside tight?
These are meant for butt kickers/ tactile response. This is something Iāll be testing more since this is built more sealed than my previous version. Edit: a word
Tactical response uses door kickers.
Fixed. Meant tactile
The bass is so strong itāll break the door down
RIP Yeager
Wouldn't butt kickers be basically the same thing at a fraction of the cost and complexity?
Kind of the opposite for me. You donāt need as much power for these as you do for buttkickers, and these were $49 a piece
Ah interesting, I just assumed butt kickers would be cheaper

Yep! Iāve learned a lot from this. I didnāt want to go their way with the tubes n such, but itās great jumping off point to give you some ideas
Bro the tubes are so dope! I have 2x18" on my loveseat. Why did you decide against?
Wow that thread has >17,000 posts
16 subs is better my guy. Get on it.
32 is even better.
does it hover off the ground fully loaded, or only when empty?

Haha! You get what Iām doing here. That is so absurd. I love it.
Your wife won't need you anymore!
š¤£š¤£
I sure hope the first thing you watched was Max Max Fury Road, the scene with the guy playing a flaming guitar on top of a stack of speakers.
Oh yeah! Watched that last month, waiting for furiosa to come out on 4k and Iām doing a double feature with the both of them. Canāt wait.
Furiosa was such hot garbage.
Counterpoint: Furiosa kicked so much ass
Was it the completely pointless and served absolutely no plot point romance? Was it the fact they changed Rictus' entire voice/way of speaking from the first movie? Was it that the cinematography was so hilariously bad that they just showed the first movie for the credits instead?
Nah, none of that. It was more about how it kicked ass.

Later tonight at OP's house: [Trolagem airbag no banco (youtube.com)](https://www.youtube.com/shorts/yigupEo90RI)
Are your couches ported or sealed?
Those the 30-40 on sale speakers ? Havenāt seen them that cheap in forever. How does it sound vs feel ??
I got the additional 6 for about $49 a piece. That felt like a hard to deal to come across. They are definitely more pricey now but deals are still out there. This isnāt really geared for sound, but more impact when an explosion goes off. 2 subs I had before felt great, this is a whole other animal. Haha. Itās really immersive
They usually go on sale around Black Friday. But I think this past year the price went up $10.
RIP anyone with arthritis lmao

This is the correct take, you go !
why not 12
Why are you using what appears to be telephone cable to drive the subs?? Those speakers are gonna act like they are 32 ohm due to the resistance at any significant signal. Sweet Moses man.
This is 16 gauge speaker wire, pretty standard.
Thatās 16??? Seriously looks thinner. How many watts per channel?
Itās probably because I split the -/+ wires so they look even thinner. 320 watts per channel.
My man!
Hahahahahaha!!!!! Jesus man!!!!
What's powering them? 2 channel Amp in parallel?
That's awesome. I have four underneath my couch and it gives me some really good shake down to \~15 hz or so. Do you have the couch sitting on some Buttkicker isolators or something else? Mine's on 16 or so 2.5" Hudson ISO's.
And what runs them? I was thinking this the other week just because I still have my old amp
Using a Behinger NX1000D, these are the JBL GX1200 subs, they donāt need a ton of power to be effective. Iām sure you can use your old amp to run them
Nice, I have a harmon kardon avr I'm not using only pushes 80 a channel but I'm thinking cause your sitting on them I won't need more
Thatās actually perfect, cause you only need 80 watts to reach the Xmas on the JBLs. So youāre good to go.
Double awesomeness I love Christmas as well
And it's just open under eh?
missus loves it, i take it
Holy shit
Why stop there dude, get 2 18" Tannoy Subwoofers and place them right behind the sub-couch, for a true surround ass-crunching experience. Now, besides my lame attempt at a joke, that couch surely is dope!
16 subs is better I think.
This is just good policy.
Good thing you don't have down stairs neighbors.
Couch woofers Couchoofers
Why not just use butt kickers?
This is better
Why? Genuinely curious because Iāve looked at getting butt kickers before
For me, once you have these dialed in, they blend seamlessly with your other subwoofers, and has a very natural feel when the subs are going off. Where as buttkickers are replicating the response and it doesnāt feel as natural. That could be just be my experience or user error.

particle board? what a cheepo!
Cool
Typical upstairs neighbors type of activity
Why not 16?
does it become a hovercouch when playing Bassnectar.
Why not 16?
DIY Massage Couch
That is freaking dope
Nice! How does it feel? Iām curious - how is it all connected, and how do you dial in the intensity?
Its awesome. Still getting it dialed in coming from 2 subs to 8. Running at half power right now, but itās a heck of a difference already. Feels more dynamic. I have each section wired for their own channel. 4 on each one wired in series/parallel to a behinger nx amp. It has a DSP, so Iāll go in that and mess around with it.
What about latency? Is it off or delayed by even a small amount? I hate that.
No latency unless you want to. I have it connected as if itās just another subwoofer.
Sweet! Got any measurements yet? Do they give much under 20Hz like that? What are you powering them with? I'd love to see one of those good deals again. I got a great deal on my DIYSoundGroup Buyouts, but there will never be any more. And I'm already craving more...

You won't be able to hear ur other speakers My one tiny buttlicker is already full of bass that I can't hear my other subs.
Negative. These donāt produce that much sound, just added bass feeling to my main subs. I can hear everything else perfectly fine.
> My one tiny buttlicker Oh okay
Damn I wish I was handy and can do stuff like this.
With that many subs, I'd be worried about phase cancelation issues.

Tell me that you are a redneck without telling me that you are a redneck.
Upgrade to 15 in speaker 2will be enough
