I installed an HT setup about 8-9 years ago and have been using it ever since. Before setting the HT up, I already owned a pair of Infinity RS5's and decided to build the system off of these. Long story short, I used the RS5's as fronts, bought a 57" Hitachi rear projection TV that I used as the center speaker, bought a pair of Infinity Primus 150 bookshelf speakers for surrounds, and drove them all with a Yamaha HTR-5660. The Yamaha receiver is starting to poop out on me. So, I bought an Onkyo TX-NR609, which does not support "TV as center". Even if it did support TV as center, I plan to get a new TV as soon as I can afford it. So, I need to buy a center speaker. I have decided that I want to do the HT correctly this time and want to get some suggestions. Here are my particulars: Room size is 29'L x 22'W x 9'H (great room incorporating living, dining, and kitchen) Main viewing of TV is 15' from TV RS5 speakers in front on either side of the TV Surround Primus 150's are 14' behind main viewing, sitting on shelves, approx. 7' from the floor The first thing I'd like to know is if my current setup is even adequate for my room size? I have often speculated that the surrounds are too small for the room. If the setup is adequate for the room, what center should I look for to mate up with the RS5's? If the setup is not adequate for the room, how should I proceed in correcting it? I'd like to use my old equipment if possible. Thanks!
