check out vmps - ewe can get a pair of their larger subs brand-gnu, coupled w/a decent used hi-power solid-state amp & a gnu marchand xm-9 active x-over, for less than *one* top-model velodyne or rel. vmps makes killer subs period - at their retail prices, they're a steal. these subs do real, clean, undistorted bass.
no relation to vmps, yust a happy customer... doug s.
