Hi.


It's been a while, as we took the summer off, but we're now back into the swing of the basement build. This weekend will be the stage.


My speakers - including sub - will be behind an acoustically transparent screen. In front of that screen (and the wall it is on) will be a small stage. This is basically for visual interest, as no speakers, subs, etc., will rest on it. The speakers will be elevated to screen level, and will sit on a massive concrete shelf.


The stage won't be physically connected to the wall, but, if I'm not going to speakers on it, do I need to worry about the isolation of the stage from the concrete slab? Also, I'm assuming I'll build this thing like a sandwich - pressure treated plywood on the concrete floor, dimensional lumber for the joists, then 1 or 2 more layers of plywood, etc. for the top surface. This is below grade and anything in contact with the slab must be pressure treated.


I've read a ton of posts out here regarding stage construction, but it always seems that speakers will be on the stage in those cases. Any words of advice?


Thanks,

Kris

Stuff it with insulation, use a double thickness top, cover with carpet and pad. Put something under the wood framing so that it can't rattle against the concrete, Like sill seal (foam on a roll) or tar paper.
