Another option would be to build bases for your equipment. I used the material that @bdp24 mentioned, and sandwiched that material between oak and granite from my local kitchen counter store. My amp and pre-amp and TT are sitting on those, which, in turn, sit on the stand. The TT is on its own supports on the wall studs. As someone else pointed out, constrained layer damping only works when you have two DIFFERENT materials - so I used granite and wood. YMMV of course.
Want to build a rack with sandwich layered dampening
Hi all,
I considering constructing a very basic, small, low two shelf rack to accommodate my somewhat compact components to replace my rather resonant Pangea rack. Lower, not as deep and a bit wider to accommodate access, but also keep it low to preserve stage between the speakers in my smallish listening room.
I’ve found some perfectly sized and precut maple (I think it’s maple will have double check). 3/4 to 1” boards that I’d like to sandwich together with screws, and place some sort of elastomer material between to control resonances. The legs would be basic but thick, and I’d probably just put spring isolators under them. Rack would be sitting on a raised hardwood floor.
My question: would using a sheet layer of sound absorbing butyl or some type of elastomer in between help or potentially harm sonics? Reason I’m asking, I’ve found sorbothane to actually have an adverse effect under components, with say stack audio pucks instead a purely delightful improvement. I know we’re talking about a different application, but still would like to get some experienced thoughts on anyone that has done - or purchased - something similar.
Big thanks in advance for anyone’s help!
John
