I think the question should have been emailed to Bose though, we all know they're the experts on speakers that produce 'room-filling sound'.




While this may have been in jest, Mirage does have an opinion on this.

They base the design of their speakers on the theory that a lot of the sound we hear is reflected sound. This is true in a lot of cases (how often are we in open fields?). That being said, the smaller the room, the greater the reflections. I believe that Decware also bases their room designs paying close attention to primary and secondary reflected waves (anything beoynd that is neglected due to energy losses and time delays). Thus, the perceived sound loudness should be greater in a small room than a larger room at the same output level. How much louder? That would have to be measured and would also be dependent on room finishes.
