I'm doing the shopping and gathering for my impending booth build, and recall that I want to isolate the final construction from the floor as much as possible - I've read and heard about those round rubber donut-looking things that will absorb and/or decouple the booth from the (carpeted but over a garage) floor. But I can't for the life of me recall the name! Even Google came up empty...Can anyone help my formerly photographic memory out??? Or point me to a better solution than 4 of these donuts, one under each corner?

Many thanks.

Answered my own post - actually I guess they're not really donut shaped, it was U-BOATS I was thinking of....Now to try and find em thru a Upromise store for my daughter's college fund!!!

Here are a couple of places to look for the U-Boats.

They are made by Auralux, so should be easy to find.

Chris, are you sure you want to go to the expense of building a floating floor on a 2nd story (above your garage?) I'm no expert by any means but my understanding from reading the info and forums over at johnlsayers.com etc. is that there's not much point in doing a floating floor on a 2nd story. I guess I just bring it up to make sure you don't spend any unnecessary money. Good luck with your build - hope you'll show pictures when you're done.

No, I was thinking this would hopefully just be a bit more isolation against trucks going by etc. and rumbling up from the garage, the plan was to have the u-boats sit between the booth and the carpeted floor - of course now looking at them, not sure how that would work. We're using the design purchased from DAWbox (YES!!!! I PURCHASED IT AND DID NOT STEAL IT!!!!! just in case someone has any question...they seem unusually protective) and are keeping fingers crossed. This calls for a flat base, so yes I'm not sure how the u-boats would "fit" in the scheme given their shape, but still would like as much decoupling as I can manage.

I took Music, Sound and Physics as a science course in college, being that I was a music major, so I know *just* enough to screw everything up XD

I am one that likes to get in a build something with the circular saw and nails and all that good stuff as you know from other recent threads....so back when I got my booth from GK (I was too lazy to build an entire booth...lol) but I built my own casterplate for my booth. I even had left over carpet that was sent with the booth from GK and used it to cover the caster plate/riser and it matches seamlessly. I have noticed a much better level of noise reduction over just having the booth on the floor.

The other thing I did was to get a brand new stall mat, which is made for horse stalls (about $40 from TSC) and cut a 4x4 piece from it to put between the booth floor and the caster plate. It is just one more layer of a surface to help de-couple the booth from the floor. The stall mat is very heavy rubber and about 1/2 inch thick. So I have the rubber caster wheels.....and the 1/2 thick rubber matter on top of the caster plate and then the booth floor went on top of that. Works pretty well.

Ben, that's an awesome idea! I've been looking for some thick rubber for some of my projects. Thanks for sharing that little tidbit.

No problem, Brian.

I also used the remaining piece from the 4 x 6 heavy rubber stall mat and cut that down twice so I had two pieces to go under my subwoofer in my studio monitoring set-up. It also helps to decouple it from the floor somewhat.

It sure is.

Other less dense rubber mats can be found at GK Acoustics/Soundsuckers website. The stall mat may be too heavy duty for some people's needs. These may be a better fit:

Also those green neoprene mats you can find at Sam's Club or Costco that piece together like a puzzle are usable in some situations.
