I upgraded from Dual sb2000s to dual SB13 Ultras, I could not be any happier. I was innitally calling SVS to purchase PB2000's because i felt that at my playback levels the sb2000's were starting to sound distorted and for HT the bass was lacking. I was ready to purchase the pb2000's and suffer slightly in the music department and pick up big time in the HT.
well not sure what came over me but before you know it i am telling SVS I called to order dual SB13s. well two big 100 pound boxes showed up at my garage door, with in an hour i had run audssey bumped up the sub gain and its total bliss. They are much tighter, dig deeper, play louder and much clearer and smoother. I am thrilled I decided to drop big bucks and buy a pair of these.
I also recently upgraded from my Polk 703's that i used for mains to a pair of Salk HT2 TL's I did get a chance to hear the HT2s with the Sb2000's but they just sound phenomenal with the sb13s. Total Audio Bliss
