Thanks so much, Andy. The ceiling tile speakers came today, and they are amazing! Of course, I don't have them connected yet, but the mere fact that they are flat and weigh next to nothing (they are pretty much exactly like poster board) is amazing.

One question, though. What guage wire should I get? I am indeed using the X10 wireless audio sender, and I'm going out to Radio Shack in a bit to pick up the connectors I need. I just wanted to know what kind of wire I should use.

*edit*
Could someone tell me if there is such a computer program that will limit the frequencies coming out of the soundcard? I guess like a software crossover? I don't want to be feeding these things heavy bass or anything.
