"Overall, the SB12-NSD is a talented bass beast that marries impressive weight with control and finesse… the SVS boasts excellent low-end extension and ferocity – but is also fast, detailed and extremely accurate."Home Cinema Choice, Review by Ed Selley, 8/30/2013.
"These speakers do everything well, and the more time I spent with them, the more I appreciated the way they could get the best out of any content in my library… The Ultra’s price/performance ratio is through the roof, and I recommend the line not only to those planning a purchase in this price category, but even to those who were planning to pay more. I don’t say this often, but I’ll say it now: I could live with these."The SB12-NSD Receives Home Theater Magazine's Top Picks Award.
"The deep clean bass the SB12 produces will improve the listening experience of just about anything you listen to!"HTguys.com, Podcast, 8/17/2012.
"Impeccable design execution and optimization. Highly Recommended."Audioholics, Review by Josh Ricci, 7/22/2012.
"SVS’s least expensive and smallest subwoofer, but it still performs in a big way."Electronic House, Review, 7/05/2012.
"Build and operation is smooth and apparently bomb proof, the finishes you're allowed are superb, its looks distinctive without being overly extrovert and it's pleasingly compact. All of which is good, but ultimately it's the performance level achieved that sets the SVS SB12-NSD apart from it's price equivalent competition... you can't go lower, louder, as cleanly as well as doing it all in such a musical fashion, with such impact, in such a small box."AV Forums, Review by Russell Williams, 6/1/2011.
"If my big sub's definition is 7 out of 10, this little sub is a 9 out of 10 (I only give it a 9 lest there be a sub with better definition, of which I am unaware)... if you are budget limited, and have a HT room around 2000 Cu Ft., you will be bragging about this sub to all your friends, and flaunting it to your enemies."Home Theater Shack, Review by Dennis Doan, 11/1/2010.
