Weapon of Bass Destruction

I have this subwoofer in a 1.45 Cu ft Seal Enclosure pushed with a Kicker zx750.1 and this sub bumps! Everything about this sub from the beefy surround to the highly convenient PSP terminals make it ideal for anyone looking for an all purpose subwoofer. I would Highly recommend this subwoofer to anyone!

Awesome woofers

I would suggest these woofers to anyone that is looking for an amazing amount of bass. Put in two of these sz-10's and put about 2 hours low volume play time on them before i opened them up. I promise people will hear you coming with these!
