First of all I want to you all to know that I love this thing. It is by far the best sub I have ever seen. As I have said the only sub I have ever heard that came close was the martin logan descent retailing for $2000 more than the SVS. Now I have thrown alot of tests at this thing. Music, movies, you name it. It excells at music. Blows away the $2000 kef reference sub at work. Its alot more accurate. Movies are incredible. Very powerful and it can play low. The only thing that the Martin logan beat it at is the Nickel test. The martin logan descent is so solid you can put a nickel on the top of it on its edge. Then crank it and it wont fall off... well the SVS did this. I played some linkin park DVD-Audio and it stayed up... until I threw in monsters inc. Then it fell over. LOL. You guys proably think Im nuts. But Im still impressed. Just really low bass at reference level is what made it fall over. Im gonna leave a penny on it for a week see how many times it falls over. Im listening to metallica DVD-Audio Black Album right now. Its incredible. I love this thing. No doubts at all in my mind.
