I wasn't very impressed with the few12s at all, for the amount of money they cost, where I saw them it was 129 each (for 12s). One of the kids that worked there showed me, I personally think the alpine Es that I owned at the time sounded better, and that to me says something. This was about 3 years ago or 2 i believe.
I mean, they're alright for their price but they don't really have anything great about them, and that kind of gets to me, that they fit the stereotype for basic sub so well.
This is all just in my opinion
