Being moronic enough to have actually purchased and still in possession of a DD-18, 3 EP-600's and a 500, an Ultra and a PB-10 and finally a pair of Hsu VTF-3 HO's, I would say they Axioms are competitive with the best subwoofers in its price class. Are they absolutely the best ? If someone has that opinion, that is cool. But it is just that: opinion, which is to be respected for what it is.
Sheep - The PB10, while a terrific performer for $429 Plus shipping, does not come close to the performance of an EP-600. Honest ...
