Thanks John, I'm with you on the port configuration. I own a sealed 10inch sub made by Energy and I have heard many a ported sub and to me, the sealed sub sounds better. Not to say that the EP500 does not sound amazing, but port design really does make a difference. I've heard some Klipsch subs with their "corner tube ports " and I was not very impressed with the overeall sound.

Good point..

Thanks
Steph
