Hello, I am building a theater room in the basement. I have the following three pieces of equipment: Yamaha Natural Sound AV HTR- 5540 Receiver Yamaha Natural Sound M-50 Power Amplifier JBL SUB 150 powered 250 watts Basement. Thinking of a decent plasma on this wall. The seating area is 17' x 17' with a small kitchen/ bar behind that is about 10' ft. The 17'' x 17" area will have a 2" trey around the top so I could mount speakers in that if needed. My first question is can I use the power amp in combination with that receiver and in a theater set up? If so, how would I go about doing it? Also, any recommendations about the following would be a big help: What a additional components Speakers ( I know I will need front 3 and at least some rears) But which, should I go for the concealed type? Speaker placement, etc? Any help is greatly appreciated!
