The room is in some respects an extension of the speaker. The speaker moves air, and the boundaries of the room affect the air in one way or another. You need the room interaction or you would not have the kinetic energy of the speaker--i.e. most speakers don't sound too good out in a corn field. However, untreated or poorly designed rooms with bad modal response in the bass region will lead to disaster, and what's worse, is that typically the better the speaker the greater the sound degredation from the room. We think of the room as the invisible component--the first thing you start with and the last thing most people think about. The only speaker that won't have interaction with the room is the one that doesn't move air in the room--basically that leaves you with headphones.
We were in 7 rooms at CES and THE Show and it was predominantly the speaker manufacturers that invited us to be there, knowing full well that the room would take away what they had intended for their design to deliver. Keep in mind, room treatment including devices like our PARC are not compensating for speakers or for electronics. They are compensating for the room--to create positive interaction with the room rather than negative--thus allowing the equipment to perform as it should.

Rives Audio There is an educational section that has quite a bit of information on different types of room interaction and solutions.
