I use an EP600 for my two channel set up and two 500’s for my HT. The single 600 was in my HT for a couple years. When I swapped the 600 out for the twin 500’s, I did loose some lower frequency LFE, but it was not enough for me to move the 600 back in the room. The only difference is that some things don’t rattle as much anymore (light fixtures, smoke detectors, door latches). The whole movie watching experience is actually better now as the LFE just feels as if it has me surrounded whereas with the single sub, it was almost directional. As far as the EP’s being musical, the 600 is excellent. I want for nothing, which if you knew me, you’d know for me to say that has some significance. The 500’s are great subs too. I had an Outlaw in my HT with the two 500’s, but have recently yarded it out. It is not nearly as smooth as the 500’s and was more of a distraction than a benefit.
