Axiom Engineer Andrew Welker continues with his description of how to design an in-wall loudspeakers to avoid any problems with reflections and diffractions1.
Andrew: Part two, in continuation of part one. A couple of important details. One, many in-wall speakers that you’ll see on the marketplace actually are sunk into the wall so that the drive units sit below where the drywall surface or the wallboard surface would be. That’s actually a very bad thing acoustically, because the wall edges that stick out past the drivers cause reflections and what’s called diffractions around the drive unit.

First of all, a speaker isn’t like a piece of art (or at least, isn’t like most pieces of art) in that it moves. As you put music through it, it vibrates and oscillates. That means when you are choosing the right in wall speaker for your installation, it’s especially important to make sure the clamping mechanism is secure, and won’t result in bits of drywall dust eternally falling from the cut-out.
