Well, this sub is going to be connected to my Outlaw 950's LFE Out...my 3 fronts (DefTech BP7002 and CLR2500) all contain built-in powered subs, and I am running them "Large" in the Outlaw. The Side Surrounds (also set to "Large") are going Speaker Level In to the Polk PSW110 and Out to a pair of DefTech BP2X'...for Rear Surrounds , same thing, set to "Large", in via Speaker Level In on a Polk PSW110, and Speaker Level Out, to BP2X'. It rocks pretty good in 7 Stereo and for Movies I'm rather impressed with the output with my current configuration...but I just bet adding a SuperCube Reference to the LFE Out will make a world of difference while watching movies...I'm just wondering what I'll give up in the 7 Stereo mode....
