I've had Insignia (Best Buy's brand), Pioneer, and Boston subs. They all hit good and loud, but i'm gettin tired of just loud. I want my bass to sound good. Everyone i've talked to who's owned JL's say they've been very pleased with em'. A guy at a local audio store let me listen to some 12 inch W1's, pushin em' with about 200 watts a piece (rated 150 rms) which hit a lot harder than I expected. He also said JL underrates their subs, and you can juice em' with about 50 more watts than the listed RMS. I'm on a pretty tight "college student" budget, so unless someone really unconvinces me, i'm set on JL! (Feel free to unconvince me!
