First the details, then my questions: I just remodeled my house and now have a very large main living area, approx 27 feet long and 15 feet wide. I am a total amateur in regards to HT setup. My couch sits exactly in the middle of this area, about 13 feet from the front JBL ND310s and PW10 sub and about 13 feet from the rear Polk bookshelf (not sure of model number)surrounds. Regardless of what my signature says, I think I am going to end up getting JBL N26 or 28s for my rear surrounds since 1) I listen to lots of music and 2) I am on a budget after the remodel and 3) I want all the speakers to timbre match. So, am I nuts with this setup? Do I need really powerful rear surrounds to make up for the distance from the speakers to the couch? Or should I move the rear surrounds closer to the couch, along the side walls? Problem number 2: In an attempt to not let my tv dominate my new room, I have put it to the immediate right of the right channel main ND310. When I get the center channel, should I put it on the tv, even though that means it will not be inbetween the L and R mains? Or should I put it between the mains, even though that means it won't be sound imaging dialogue from the area of the actual picture? Thanks in advance to anyone who took the time to read all this, much less answer my newbie questions.
