Setup my SB12-NSD a few hours ago. I read all the reviews and decided to give it a try before the return period ran out on my B&W sub.
Like all the other reviews, all I can say is WOW! I'm really impressed with the sound and how this base fires and provides fill. The B&W was really nice but it does not kick in on the suttle low notes that this SVS does. In other words, I'm hearing base that I did not know I was missing before.
I also bought a PB12-Plus for my home theater. I cant wait to set that up now but that wont be for a few days.
I'm so happy right now that I came across SVS. With the SVS bill of rights, how can you go wrong? There is no reason not to try them first. Worst case scenario is you pay for shipping to send it back, however, there is a reason this company can offer such a great (45 day) trial deal period is because it's highly unlikely that a person would not be satisfied. Just knowing I can upgrade within one year using the full price I paid for my sub is just amazing!!!
