Looks great Hopinater! Now to get you a few TT's and then have you report back what your impressions are.
I do love how they feel, and even yesterday I ran the barrel roll scene from FOTP with the buttkicker's off, and then on. Definitely could feel the difference. Now to get wonder woman, after seeing the graph that MrGrey posted, should be a great ride.

I can't tell from pics or posts: did you get 3/4" plywood? Also, have you/will you remove any feet from the sectional in order to couple the entire base frame to the plywood sheet?

I haven't looked under my own sectional but my setup is similar to yours--a three-seat Lazyboy includes a divan and recliner, atop a commercial grade carpet, then a special pad (for my in-floor heating) and finally concrete floor.

Will be interested in your report. Oh, another question: are you concerned those Buttkicker pads might mar your carpet long-term?

You need this t-shirt. I'm not crazy about sports either, nor was my roommate a few years back. He picked up this t-shirt and around here, NASCAR isn't super big, but dang he still got some dirty looks! I can only imagine if he wore it further down south...

Good questions. I went with 15/32 plywood so it's basically 1/2 inch. I went with this because it looked to me like the 3/4 would be over kill.

I considered removing all the round feet from the bottom of the couch's frame and was about to do so until I saw that if I did the couch would be riding on the nuts attaching the cross pieces of the frame. So the feet are important and act as spacers and had to stay on.

I don't really have a fear of the Buttkicker pads marring the carpet because they seem to be made of a non-marking material. I could be wrong about this but I don't think I am.

It started my PSA sub-fund , I think I threw my SVS subs out the window the same night.....Actually , I was too wasted the actual night , too hungover the next day , so about 2 days later I threw them out.....

Now after seeing how great it sounds like even a simple piece of plywood works I'm like [email protected]?! am I going to do with $800 of rubber flooring that I can maybe sell for a $100 lol.

I won't be finishing my basement anytime soon but I am thinking of skipping the rubber with plywood over it as that will be a lot more work and $$$. Sounds like a carpeted piece of plywood will help a lot and then near field subs I think I will be pretty close to what I am getting now on a suspended floor.

I just looked at Soundproofing Companies site and they also show it without wood over the rubber. Maybe I'll just do that since it will help some with insulating the cold concrete floor from my feet in the winter and I won't end up giving the rubber flooring away. And just put a piece of carpeted plywood under my MLP verse cover a 23.5' x 18' room with it.https://www.soundproofingcompany.com...lution-1.3.jpg

What I originally wanted to do when I first built the theater room but was unable because of the height of the ceiling was: lay 2x4's flat horizontally every 16inches and lay insulation between them. Then I was going to put 2 layers of plywood on top, the 1st layer I would lay vertical and the 2nd lay horizontal covering the seams of the 1st layer. I would glue and screw the 2nd layer to the 1st layer and to the 2x4s to eliminated any creaks and I would make sure the layers of plywood did not touch the outer wall to create a floating floor. Then run some noise-proof sealant between the plywood and the outer walls.

Ah, sure. Another thing to watch-out for (to others) is the mechanism for any recliners. I recall a sectional I had with an integral folding footstool--the metal inside actually touched the carpet underneath even with the proper factory legs on it!!!

Nice! This is similar to my build, but i used a few cheaper, slightly harder penn elcom rubber feet and mixed them with the Crowson isolators. I drilled holes in the plywood to line up with the extra frame holes that are adjacent to the feet (was a bit of a pain to get them all perfectly aligned), removed the original couch feet and replaced them with a simple nut and bolt to keep the height down, and attached the isolation feet; it makes an excellent solid, unified base for the Crowsons to work under.

If your couch fame has extra holes next to the feet for different spacings (mine had a bunch), you just drill and align those holes with a few nuts and bolts to connect the couch directly with the plywood. Being directly connected to the riser might help a bit with TR and will really help when you eventually add those bass shakers you're eyeing.

Haha you guys are funny.

I personally love football season and couldn't wait to sign up for the PSA fantasy league after I saw Tom's post. Looks like I got in, so now I'm looking forward to the season even more!

@Hop inator how high are the isolator feet, Jim gave me a bunch of extra sub feet when I picked up my 01s and I'm thinking of using them, don't seem much different than the PE's. This is going to be a pain for me, my couch weighs about 300 pounds to begin with and the feet are 4.5" squares and 5"s high. I'm going to wait and see what you think and listen to the 7201 in my space before doing this anyway............

I spent the whole day today moving my speakers and MLP around so I literally have about 5-6 possible spots for the 7201 to fit quite comfortably in. I just hope the best spot which produces the flattest FR will be the nicest looking location to show off the beauty of this beast. I don't know who I would be trying to impress except myself anyway, so I guess any spot will be fine as long as I get the best FR and TR......looking forward to your impressions my friend....

Hey climber, where is the amp located on the back of cabinet, I never bothered to look when I was down at PSA HQs, matter of fact I didn't see a picture with the amp's location on the cab, am I missing it on the site or is it not shown, thanks buddy?

Full disclosure, your design was my inspiration. When I saw what you did and how easy it was I decided to do the same (so the credit definitely goes to you). The nice thing is I have enough plywood left to do the chair I have in the room.

I was planning to build a riser similar to Toe's but since this room isn't a dedicated HT and we use it as living space it just wasn't practical and this looked like an elegant solution.

Jeff the isolator feet are approx 1in. They are a moderately hard rubber that allow for some (but not too much) compression. I decided to buy these based on Mark Seaton's post regarding decoupling and the importance of the feet compressing slightly. These are the feet I used...

On another note... in the picture I posted you'll see I used all 10 feet. But the more I thought about it the more I started to wonder if that may not have been too many because the more feet I used the less they would compress. So yesterday I removed four of the feet. This also gave me an extra four feet that I can now use to make a platform for the chair in the room.

I was planning to build a riser similar to Toe's but since this room isn't a dedicated HT and we use it as living space it just wasn't practical and this looked like an elegant solution.

I got the idea from Randy Crowson after he told me the benefits of adding a solid base instead of my plan to simply place the actuators under the couch feet. My shared living space is also why I did it this way; I don't think people can tell the couch has been modified until the "booty rumbles" kick in. I do joke about the motion hardware costing more than my couch now, lol.

I also added a few too many feet. I showed my build to Randy and it was suggested I use a couple less feet; but I haven't changed a thing, and the TR experience is still amazing. The newer sorbothane feet from Crowson are expensive, $40 each I think, but the two feet that came with my kit are very nice. Might try the BK feet next if I replace the harder penn elcoms.

Having massive bass output down into the teens coupled with motion actuators rocking all the way into the single digits provides a very unique experience that I didn't think possible in a living room. I'm about to watch Battle L.A. for the first time since adding the V1801s...if I can handle it.

>>> PSA Gamma 21s for sale! <<<

So I was doing some Googling and came across an interesting page. I asked Tom about them and yes, they are real and both are still for sale as of today. PSA took in a pair of Reaction Audio Gamma 21 on trade and fixed the DSP big time!

For comparison, from my chat with Tom V:
  • 10-50Hz one G21 would be similar to dual S1801
  • 60-100Hz dual S1801 would have ~4dB advantage over one G21
  • Driver is made from Pierce Audio

Be sure to chat with Tom for best pricing.

I contacted Tom about the G21's a couple months ago...The price is really good, but I think the fact they are a Reaction Audio product with no warranty makes it a tough sale.

Bass, what's warranted, I think the amp is for five years, correct. What else can go wrong with a RA product...............

Jeff the isolator feet are approx 1in. They are a moderately hard rubber that allow for some (but not too much) compression. I decided to buy these based on Mark Seaton's post regarding decoupling and the importance of the feet compressing slightly. These are the feet I used... Toe is the one that posted a link to them or something very similar to them.

Hop: How much room do you have under the plywood once the couch is on and butts are on the couch. I can slide a piece of paper under the plywood while using the furniture grippers.

I'm glad you asked me because I would not have thought to look.

With the six pads I had between 1/8 and 1/16th of an inch between the plywood and the carpeting (not much room for error or a heavier person). Of course this was in gaps between the rubber pads, not near the pads themselves which were 33 inches apart.

It shocked me to see so little space between the carpet and plywood considering the rubber pads are one inch high. So this shows how much everything sinks in when you take into consideration the carpet pad, carpet and rubber pads.

Needless to say I put the four extra rubber pads back on which reduced the gap between them to 22 inches and raised the space between the carpet and the plywood to over a 1/4 of an inch. I hope all of this makes sense.
