Actually, about 3 to 4 years ago, PSB Subsonic6i absolutely crushed Velodyne and Outlaw's LFM in a sub shoot out playing both louder across a larger freq spectrum and deeper then both. Thats was 3 to 4 years ago and now both Outlaw and velodyne has gained the upper hand. When I chose my PSB sub over 6 years ago, Axiom's 10" inch model (mine is 10" as well ..no not talking porn

) just couldn't compete with the PSB sub. It was too anemic. It actually sucked.
The point I'm trying to make and i made it with the B&W vs Totem post is people need to audidition for themselves because everyone hears differently. Its not that PSB makes a bad sub. Far from it. But for the money, one can buy better performing subs.
