12-inch single voice coil 4 Ohm subwoofer
The kind of bass performance you can hear!
•1mm thick mineral filled polymer composite cones mean an ultra-stiff and superbly strong cone design that can withstand the tremendous pressures produced by today's demanding listener.
•Genuine rubber surrounds completely eliminate any chance of the dreaded "foam rot"!
•Injection molded solid polypropylene dust cap prevents any distortion due to the unwanted build up of air pressure behind the cap.
•A precision 4-layer, 2.0-inch voice coil completely handles harmful heat produced when your amp is realy pumping out the power.
•Using a special vented pole piece allows cooling air to circulate around the critical voice coil extending the longlife capabilities beyond other designs.

Accuracy is outstanding - very tight and strong bass.
Wiring terminal could be improved - one snapped in half - replaced it with banana lugs.
Two EX12's installed in 0.8cuft per sub acoustic suspension enclosure. 160W amp driving them. Overall sound and accuracy were outstanding. Took first place in local MECA competitions. Achieved 136.1dB with this very modest setup.

Deep Rich Bass. Never failed me in the past 12 years or so. suitable for small enclosures.
I can not think of any weaknesses with this sub. Its been working great for me for many years.
I've been using one of these EX12s for the better part of 12 years. Its never failed to produce clean deep base. I'm running it with a 380 watt amp, I know its way above RMS, but i don't listen to it at insane volumes so I've never had a problem. I have this in a small, sealed enclosure. This sub has lasted longer than some of my cars have and it sounds good in every vehicle I've had it in. Thanks Polk Audio for making outstanding quality products.
