Kicker L7's aren't shabby.. JL W7's rawk. Really, if you're going for the average sub price, they'll all pretty much do. Never had a problem with JL Kicker, Polk, Ztant, Orion (do they even make subs anymore?) Pheonix Gold, MTX, Or Rockford Fosgate. I've ran them all. My Fav's were Orions, followed by JLAudio, then MTX
