I use in wall speakers for rear and surround duty. My research indicates that building an enclosure should increase low frequency response. Something most in walls/ceilings lack. In my instance I installed one on a outside wall with insulation. The other in an open inside wall. I feared I would get different acoustics from each so I built an enclosure out of MDF for the open side. Did it make a difference? Well.... after a few hours of banging my elbows around inside a wall I suspect it sounds much better. At the very least the in walls produce an even response. As a side note several companies market pre-fab in wall/ceiling enclosures (I beleive Polk is one) but they are quite expensive. More than the speakers themselves in most instances.
