Hi, I'm installing a HT in my living room. I'm building one wall out so that I can build the TV and AV rack into the wall for a custom look. The wall will be a standard framed drywall wall with openings for the TV and rack. I will also be installing in-wall speakers into the wall, and that is where my question lies. I don't think I'll need to drywall the backside, since it's a non-functional wall and you won't be able to see behind it anyhow... which means I can't insulate it, which should be okay since it's not a real wall anyhow. So what should I do behind the speakers? My thought was to frame around where the speakers will be, drywall the backs, and insulate those sections only. Or would it be better to build a small insulated cabinet behind each speaker? Or should I worry about it at all. Any and all comments would be greatly appreciated! The front speakers are JBL HTI-6 loudspeakers and the center is a Niles HD-CTR. Thanks!
