Hi Jack, I don't wanna get tit-for-tat, but I wanted to be clear. Axiom did not specify the "ultra" which is the top of the line SVS cylinder sub. They said it "largly outperformed" the SVS and HSU subs, I did not pin them down exact models, maybe I should of, but it was just a general synopsis. I would have to assume they were speaking of subs in the same dollar/market arena. The ultra and the 500 are with-in one dollar in price!!! They did side by side direct comparisons in the same enviroment, and the Axiom was "amazing" and "dominent" As with anything, time will tell.
