Let me add to the question. What if half of the back wall in the room is open to the kitchen or another room? Are they considered seperate rooms or do you combine the footage?
How big is it?
I read a lot about "big rooms" and "small rooms" when it comes to speakers, and they say room size matters, but how do they measure? My listening room is 21' x 24' and in my neck of suburbia it's a very large room, but they guy on the hill might consider it a closet. So when we're reading about a speaker needing a large room or small room, just what do they mean?
