The ZP12D4 Subwoofer have been engineered to offer optimum levels of SPL while maintaining a wonderful sound reproduction and fantastic sound quality. We have used precision designed soft parts such as our OFC Voice coil and woven tinsel leads for optimistic power handling, a non pressed paper cone for the best dampening, triple polycotton spiders for accurate movement and a tall but perfectly proportioned surround to give the optimised amount of linear excursion to cone area to deliver the most amount of bass possible. To drive the engineered soft parts a double stacked ferrite magnet with an accurately calculated pole piece gap for the highest gauss possible within the parameters of the subwoofer, allows the woofer to be driven with excellent power and exquisite precision.
