Hey everyone! I just got (what I think is) a great deal on a set of in wall speakers and am trying to figure out the best placement for them. The speakers I got are Klipsch Front Left and Right Channels are R-2650-W II, Center Channel is an R-5502 -W II , Rear channels are R-2650-C II and CDT 2650-C. I also have an Onkyo NR-626 receiver. The problem is that my TV is mounted in the corner of the room above the fireplace and the room opens up to my kitchen/dining room (I am attaching a floor plan for reference). Additionally, the ceiling is vaulted. Is there any good way to mount the speakers? (I am willing to buy 2 more speakers if a 7.1/7.2 system is viable in this layout). Also, what subwoofer should I buy? I mainly play video games and watch movies but I would also like to be able to listen to music. Any help is appreciated. Thanks!
