Ive added a Polk F/X wireless rear speaker to my setup, which is essentially a wireless, powered sound bar for the rear (sound/ effect is not too shabby actually!). The problem is, it doesn't have a built in volume control, and its LOUD even when I turn the 5008's speaker volume for the rears down to the minimum of -12. Can you think of another way to lower the volume? I can't, except to bump up all the other speakers by +10 or so... but if I adjust Audysseys individual speaker volume settings up like this, does it essentially kill the acoustic dynamics Audyssey has set up, or am I just making things louder as if I turned up the main volume (might be a ? for the Audyssey thread)? Of course, ideally I would be able to turn this Polk unit down with a simple dial down, so first and foremost, any thoughts there?
