i was really gonna get a 12w6v2 in a ported box... it was my top choice till i found out about the brahma. i know the bumpin03 had 2 12w6v2's in a sealed box if you wanna talk about it, he says they were really nice. the only thing that i perfer on the w6v2 is that it only needs 600 or so watts, and they can still get loud and sound real nice.
but really if you get a 12w6v2 and a jl 500.1 amp, its gonna cost about 750$ or so, and i can get a brahma 15 with a ampman 1600.1 amp for about 50-100$ more. so im gonna go with the brahma, it has goos sq and spl that would compare and possibly beat teh 13w7.
