that's why I'm debating...but sq is where it gets expensive and I'm spending less then the 4 12's with equal output - 1db @ 35 hz(according to wsd comparison) and room for future growth...In other words I don't ever see doing 8 12's but maybe (big maybe) 4 15's
and when I consider spending $4k on front stage, amps, h/u, alternator and baterries an extra $450 isn't that bad for the best Sq
