I recently bought dual PB12-NSDs. For the first hour or so I had them on carpet supported by wood structure (second floor of my home). It didn't take long to realize they were shaking the house way too much! Since then, I've had them on the packing carboard/foam that came with the box. It's actually working pretty well but obviously not attractive enough.
I was considering building my own isolation riser. I looked into some Owens Corning 703 (I was thinking 2 or 4 inches thick) and I was going to attach it to wood to make the riser. All things in, the cheapest I could do this for is probably about $45-60 in total and I'm not exactly sure it would look pretty.
Since the basic foam worked so well, I thought maybe I could just use that same foam from the packing materials and glue THAT to the bottom of some wood covered in fabric. That would be like $15-20 in total but again, it wouldn't look too good.
So that leaves me with the standard Auralex offerings at $99 including shipping for two GRAMMAs. The studs at the bottom of my PB12-NSD are about 22" apart in one direction and 15-16" apart in the other direction. The Auralex GRAMMA measures 15x24" (can anyone confirm this?). My questions are:
-Is the GRAMMA overkill/a ripoff? Should I just make something with wood and generic foam that would perform just as well?
-Since my sub is just a little too big with the studs in for the GRAMMA, would I get good isolation performance if I unscrewed the studs and just laid the subwoofer directly on the surface?
Thanks for any input,
Mike
