Thank you for the responses.
Jrosemd, those definitve technology speakers are 50.5 inches tall. The bottom of my TV is 36 inches from the floor, so they are too tall. there is a doorway about 8 inches to the right of the TV so I need speakers that fit under the TV. Also, I would be afraid a 12" sub in it would give too much rumble. I have been looking at towers with speakers 6" or less to get away from that rumble, because the wife doesn't like it. Plus it typically makes it more difficult to understand dialog. I bet they do sound great though.
Mesch, the room is actually pretty big. Probably around 38 feet long and 25 feet wide, with cathedral ceiling and balcony open to the 2nd floor. We sit about 15 feet from the TV. To top it off , have to be careful about a speaker sticking out into the doorway to the right of the TV because when the dogs get excited they go running past that doorway. 125 pound Great Pyrenees are not so concerned about what they destroy when go running by. it was my first Pyr that destroyed my ADS 690 speakers as he would send it flying when he would run by. And he was the most gentle of them.
