Greetings!
This is my first post here. I've been an avid HT enthusiast for several years. I stumbled onto this site (I'm a member of several other A/V forums as well) looking for reviews of SVSound's new PB13-Ultra as I am seiously considering adding one to my system as an upgrade from my current sub (Polk Audio PSW 650).THe 650 is a good little sub, but I yearn for the low frequency capabilty and the power of the Ultra. Good stuff here!
