As a 30 year audio fan, we decided to try to build the coolest sub box ever, then give it away at Barber Small Bore in the Dodgeball Deathmatch to help raise money for Children's Hospital. JL Audio sent us one of their uber high end 6.5"s, and we're simply amazed. The eyes tell you the ears are lying. This thing will outwork any 12" I've seen. Just a ridiculous amount of control, power, and volume, and a low end reach that never ends, which my common sense says shouldn't happen....
