Larry, I built a sandwich for my amp, works just fine. I used 4X4 lumber for the legs of the stand, and the top shelf was screwed into the legs. The top part is as follows: 3/4" BC Fir plywood, then a 1" rubber mat, then another 3/4" BC fir plywood layer for the top. The rubber mat is the kind you would use in front of a door to wipe your feet on, cut to size. The mat is solid on the underside, and ribbed on the top. I used contact cement to attach the ribbed part to the bottom piece of plywoood, and contact cement on the smooth underside of the mat to attach to the underside of the top shelf. I then used 4" screws to attach the shelf to the 4x4 feet. Voila, instant amp stand, total cost about $50. Oh, this stand holds my BATVK500 amp (which is 105lbs) without any problems at all. Kinda ugly, but the stand sits in my furnace room directly under my speakers (the speakers are in my family room, the floor above the furnace room). Hope this isn't too confusing and of some help, Jeff
"sandwich" platform for amps
I want ot build a "sandwich" platform for my monoblock amps. I undrstand a "sandwich" approach is best, that is, maybe 3" of acoustic foam layered between either mdf or maple wood shelves. Where dos one buy acoustic foam, and what kind is best; I know it must be very dense. Thanks, larry
