The room size in on the smaller side, I would say 18x14 wide, but it does open into a dining area, we just kind of shut down at the French doors leading to the outside with home theater chairs, which would be about 10 to 12 feet from the listening area. I would say right now I use it mostly for movies, because the def tech bookshelf speakers are not really that great with the sub I have. But once upgraded I would say maybe 70% movies 30% music. I like to crank things up, especially a good movie, or some good music when I am in the mood.
