I thought that I might have come across the wrong way. I originally joined the forum to ask a question (which I did after my initial post), then ran across the sub question. I like my SVS sub, so I commented.

The PC-Ultra and the EP500 are very close in price, shipped. The PB-Ultra costs more than the PC-Ultra, and costs more to ship, as well.

Since I'm considering Axiom speakers for my next HT upgrade, I'm almost sorry I bought the SVS sub. Not that I'm disappointed with the performance, but that I could have saved money by buying an antire HT package from Axiom.
