OK. Thank you both for your responses. I still don't understand why the PC2000 did not get a Bass Extension score of 5. So it is a value score for performance? That is odd, since there is a value category, but it's helpful to know. At this point, this sub is almost the same price as the PB2000 and the PC2000. Considering the state of affairs, would they be rated equally. I am trying to chose between these and SVS offers better support and more piece of mind, but the sound is what counts.
Are these all really on par with each other?
