don't mean to hijack the thread, but... I'm in a similar spot. I'm looking for wall-mount speakers -- something reasonably small. I was thinking of the Onkyo 750 set, but poking around the forums here, it seems like folks aren't too hot on the Onkyo speakers.
I have a 5.1 system. I have a sub that I could use for now, though I wouldn't mind a new one. I have probably $500 that I could spend now, maybe a little more.
Any suggestions? How about the Polk Audio RM20 set?
