My room is approx 12' X 22' with cathedral ceiling that is approx 13'. Equip, TV and main speakers are along the long edge of the room. It does open through a bar area into the kitchen and into the entry way hall and halway into the rest of the house. I do listen to a lot of music mostly jazzy (Steely Dan) and sometimes more classic rock, but also acoustic guitar and classical. I probably watch 3-4 movies a week either on disc or sometimes HDTV broadcast. Am hoping to keep it to one sub, although there are advantages with two.
Also, noticing a couple of Rythmiks in the $974-1124 price range. That's still in the ballpark. Just not wanting to spend 1500-2000+ for subs.
