Exactly what he said. I ran JL at one time(few years back), and they are overpriced, overrated, and overhyped subs. I've seen the W1, W3, W6, and W7 all in action, and you can get a lot better subs for the money you spend on JL. Hell, most brands you can buy 2 of each compared to 1 JL they are so expensive.
