For the heck of it I placed my HT subs in the back corners of my "V" room a couple of months ago. Each has a dual 12" Dayton, powered, in a sealed cabinet. After a bit of work with REW, I have a very nice result. In my case the volume of the rear subs is a lot lower than the servos. When I get my HT up and running in the new house I'll need the subs back, but I'll replace them with a couple of Dannys offerings then. I really like the results.
