I have the Onkyo TX-SR702 receiver and a new 42" HDTV. The space is 15x25 (in feet). I'm looking for a 7.1 configuration of speakers, 2 of which I would like to be in-wall (surrounds L&R). I have a budget of $2-$3K.
Check out Orb Audio. Not sure if they have in wall, but the sats look cool, the sound is top notch (great bass and awesome sound-stage) plus it's a cool company to deal with. What kind of monitor do you have? I'm looking to get something new.
