#1 · Here's the room diagram of the speaker layout. The Center is a (t30) Polk. The two back speakers are (xt70) there on there sides on my back self. The front (R,L) are little ( JBL's 135sat). I have a Yamaha rx-v1200 as my receiver. My TV is a 32" Roku tv, eventually I want to change it to a 44" Roku tv. I recommend not to put holes in the ceiling or wall's but if I have to I will. I hope you guys can help me out. Thank you I appreciate all of your guys advice.
