Pros: Excellent sound clarity, good daily driving bass Cons: Not meant for competition!!! BottomLine: These subs are some of the best on the market. They are a little expensive, but they hold up seemingly forever and sound great!
Pros: JL quality comes through again. Cons: Overall Loudness (single sub) BottomLine: Bought used from a private Ebay user. Would recommend this sub. From previous experience it's pretty hard to "break" JL subs.
Pros: DMA Motor, large progressive-roll spider, exceptional Xmax(16.5mm), 6 patented/pending technologies Cons: None. Overpriced? Check on Ebay then. BottomLine: If you want your bottom end (bass) to have tremendous impact and amazing sound quality, the 12W6v2-D4 is a great choice.
