That looks like a pretty cool speaker, btw. I like the way it locks into the plasterboard. Btw, when I put some inwall speakers in my house, I used a Rotozip tool to cut the hole. It's like a super fast drill with a side cutting bit. You can set the depth to just slightly deeper than the drywall, then carve out your hole along the lines you have drawn. Only, the thing is very loud and it spins so fast it's kind of scary... *grin* Anyway, those axiom speakers will be on my short list next time I help someone with an in-wall install. Later...
