AVDUDE, you may want to try pulling your centre channel to the front of your stand....

I really enjoy my HSU and think it's great, the EP500 can definitley pound more and push more air though. I returned the 500 for a couple reasons but mainly the extra cost vs performance. The HSu comes really close, and since mine hides behind the sofa the color mtaching doesn't bother me
