I am in the middle of my theater build, and was hoping for some input on speaker placement.

My room will have a false wall for the front screen wall. The speakers (L, R, C and sub) will be behind some Dazian CCC covered panels. When I carpet the room, should I run the carpet behind the panels, and set the speakers on those, or should I stop the carpet at the panels (sitting on the stage) and set the speakers on the plywood? the stage will be filled with fiberglass insulation (I don't have the load bearing on the floor to fill it with sand). I have not yet decided if I will glue/nail the stage down, or leave it "floating" to help decouple from the floor - but then I will worry about extra vibrations in the stage...

anyways, any help would be appreciated.

Rob,

In my riser build where I'm putting 10" subs into the riser under the chairs I put 1 layer of 1/2" drywall between the sub and plywood to help with vibration. I am adding carpet but it won't be touching the speaker just edged in around it for easier removal (if needed).
I've got a few pics up on my thread of how I did the build. (the carpet isn't in yet hoping to do that this weekend).
Cheers
Calvin

Set the speakers on the carpet!
