I owned a pair of the 12" lanzar max square subs for a while, because they 'accidently' published the ratings for the lanzar heritage 15" sub, which is 1000rms/2000max, while the speakers i bought were SUPPOSED to be rated 500rms/1000max.
Needless to say i was very unhappy when they arrived, since i got them to replace my 12" l5's that i blew up off my opti2000d, and the max's lasted a few days till they too blew up, and i got out of car audio for a while after, and because of that.
Sorry for the rant, this thread just reminded me of that glowing experience.
If you're considering lanzar, i would stick to the heritage and optidrive product lines. Good luck! And the max's have been out for a few years now, i think i got those 12's in spring of 2003. They're supposed to be their 'street team' product line....
