I have one for trial, but it won't be going back. I've owned a few subs, Infinity Kapa-212, Definitive Tech PS-15, Klipsch (can't remember model, had 12" driver), and a NHT-SW3, and have heard numerous others including a few I really liked by M&K, REL and Vandersteen. I got rid of each sub after a short period of time because I wasn't happy with the way they integrated with my system and I could never get the kind of cohesive sound and performance I was looking for. I read a ton of positive reviews about this sub and since you get the trial period figured I would give it a try. All I can say is WOW! It may not be the nicest looking sub around, but man is it a performer. Clean, fast and detailed. I was able to dial it right in with a pair of Maggie MMG's (soon to be replaced by 1.6's) which is not an easy task. They have bass you can feel and are great for music and movies. I really like how you can integrate this sub without the usual midbass hump. You forget it's even there until needed and then it roars to life just as a good sub should. I don't think it's going to be long before SVS becomes a real power house in the sub industry.
