I'm thinking about building a listening room. It will be a concrete slab. I'll be using carpeting in the room. Should I put plywood down on the concrete first or just carpet over the concrete?
You'll feel more bass with a suspended floor above the concrete. Depending on the size of the room, and the speakers used, you could be fine either way.
Mike, I've seen concrete work but I would float a floor if I had the chance. 2X6 or 2X8 with 12 or 16 inch centers would be great for flooring on a concrete slab. You didn't say what your equipment is so it makes it a little bit harder but I've heard analog gear with friends of mine and you don't want to have a lot of bounce in the floor which is why I would keep the centers closer together.
Q-man, Carpeting on a concrete slab is done no matter where you live. I'm more interested in the sound quality of one versus the other rather than building practices.
Boss302, My gear is a digital front end to tubes to horns.
In that case, put the carpet over the slab with some good padding. You don't need to add a wood floor and open your room up to potential vibrations. You also don't need the low frequency waves reflecting between the slab and the wood floor above it.
I like block walls instead of studs too.
Horns huh? I love horns. My home theater room speakers are all fully horn loaded.
