Housewrecker vs. Imperior Horn ... which would you recommend for a basketball coach trying to fill the gym with booty-shaking bass.  I run a bball clinic for middle-school kids called The School of Funk.  Lost our ability to use the gym's PA system.  Picked up a Behringer powered amp that allegedly will give me 1200 watts in bridged mono.  I've got the mid-range covered.  Now I need to rattle the bleachers with deep, wide bass.  Figuring to load them with 15" Daytons (everyone seems to like them)  So ... Housewrecker or Imperial?  Your opinion, please.

Thank you very much for the advice.  This is what I just got done building and am very dissatisfied with both the efficiency and bass.  Admittedly, I did it on the cheap (15" Pyles for $28/each), but was hoping for a bit more sound.  Just not getting it.
