I baught two peavey headliner one twelve bass cabinets and a peavey minimega amp.. Thousand watts....wanted a compact bass rig. but a powerfull rig as well...realized the stalk speakers in the two cabs were not going to cut it...so i called chris at peavey for input...he siad with the speakers you propose to put into the cabs would work..and you will have one heck of a huge wall of sound comeing at you. so i got two of the one twelve eminence definimax speakers droped in...both cabs are turbo charged and can handel hard slaping... drop tuneing anything you can throw at them at excessive volums with minimal speaker excursion...could not of done it with out american musical supply thanks for the great gear

As good as I expected it handled my 1000 watt rms amp with ease.

Product Review

I don't know what people expect from a 12" sub but it is a supreme item. I play it at 94% max only it is a good setting for my 1000 watt amp, it has a great sound and lots of punch for a speaker this size. I Have two of them and I am not disappointed in their performance. Excellent!
