anyone have any experience with JA Audio in wall speakers? I'm looking at these http://www.inwallstore.com/jatheater.html looks like a decent deal for putting something into a living room HT set up. I'll be using an existing Kenwood 5.1 receiver (don't have model off hand) and an old Infinity sub. any input is appreciated (putting the BIG HT install on hold for a while ;) this is just to satisfy the need for HT for a bit)
