I am by no means a kicker fan (unless we are talking old school). BUT...L7s are an exception to that. I came across an L7 15 for $75 and jumped on it. Im a college student and before I even had it in a box I had it hooked up in my dorm room shaking the crap out of the ceiling tiles. In a ported box it can get hard to breathe with just one of these. They're loud no doubt. Are you going to get the sound quality of a JL W7? No, kicker doesn't do great sound quality, but will you get stupid SPL that tears things apart? yes, and honestly that's what this sub is, loud and fun. Is it worth the price,thats up to you and what you want from your system.
