Thanks Alan. That’s some interesting reading. So, from what you tell me, even with a sub I’ll still feel the urge to crank up the volume. But what do you think about my idea of adding a sub in this room? Will it help fill the room at the lower volume levels?

Unfortunately, in the mult-room configuration, the receiver does nothing more than pass the stereo signal through to the speakers. I can not manipulate the bass and treble controls, or balance either. The only think I can change is the volume. I can’t use any of the H/K’s surround processes either. I’m pretty disappointed about that. If I would have known, I most likely would have bought something different.

Who makes a good, less than $1000 sub that would match up with the 80’s? One big enough for this room? Are the Axiom subs any good? Are there any other nifty electronic gizmos out that would give me some control over the bass/treble signals between the receiver and speakers? What about round vrs box, any difference?
