I would love to know that as well, but I do have some perspective on it. I am sure that if the EP500 doesn't quite match up to the Ultra, many of the SVSers will jump all over it because of similar price points. Even though they are the same price, they are of different sizes. I am coming from higher priced smaller subs, and you definitely pay a premium for a smaller with performance. Not that the EP500 is small by any means, but with its size, I couldn't have gone with the Ultra even if it outperforms the EP500.
Of course if the EP500 does matche up to the Ultra, I would be thrilled.
