I'm New to home theatre and recently set up my 5.2.2 system with yamahah tsr 700 receiver and all New Sony tower speakers, center, Sony atmos for front presence, and Sony bookshelf speakers for surround. 1 sony subwoofer 10inch and the other is polk 10 inch. Is it ok for the atmos speakers to be not directly above the front tower speakers? Is it worth it to splice wires to bring them out from ceiling so they're directly above them? In wall wire that came with house is not long enough.. Also when I use the ypao optimizer it sets my front towers and center to large speaker setting, but I have two subwoofers. So I change them manually to small so the subwoofers work. Not sure if that is correct or if something is not configured correctly? I feel like I'm not quite getting a full surround effect. I appreciate any helpful tips. The atmos speakers are about4 to 5 ft from the front towers length wise.5 on left I think 4ft on right . Alsowith the yamahah receiver should I get back presence speakers even though the receiver only picks between front and back per audio source? Or just stick with only with front? I appreciate the help. Thank you.
