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, 1.5-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.
