V2? If so, I can't comment on it. I chose my Mag over the W7, but the W6v2 supposedly sounds much better than the W7. Now, I have owned many a first gen W6 and the AEs, but none of them could compete with the Mag in either category.
I had a buddy with a pair of the 13W6v2s, but both were in a huge vented enclosure with 1KW per driver, not exactly SQ oriented. It got loud, and sounded pretty good, but even he preferred my Mag over them.
On another note, I've never really been dissatisfied with any JL product. They are all capable performers.
