Room size


You read so many loudspeaker and subwoofer specifications and how they're rated for small, small to medium, medium to large, & large rooms. Would someone finally define for me what these sizes are dimensionally? My listening room is 23' x 13' x 8' high with two exits to other areas (uncloseable openings). Is this a small or medium size room? It's on a first floor slab, no basement (oversized family room). I am using a pr of B&W DM601 S3's, an ASW300 Subwoofer, and two B&W M-1 satellite speakers powered by a Marantz A/V receiver at 90 watts RMS/channel x 7. I got to tell you the system rocks !! Yet these speakers and sub are rated for "smaller" rooms. This sub is considered small and mediocre in power but I've got to tell you, it has one helluva a punch. You can feel it in your bones!! Please someone clear this up. Many thanks.

In THX parlance, a large room is defined as anything larger than 4500 cubic ft. I think the parameter for small is anything smaller than 3500 cubic ft.
I should add that if the room is not enclosed, you need to add in all of the open cavaties as well. The basic cubic volume of your room is less than 2400 cubic ft, so it rates as a small room. The additional openings suck up some power, but I doubt you would notice it in your listening area.
