and

wound onto Nomex reinforced Kapton formers, and are available in 4Ω and 8Ω versions. The voice coils are cooled and given increased mechanical damping through the use of a ferrofluid filled magnetic gap. The cooling, and therefore power handling, is further enhanced by virtue of the inverted coil geometry , together with a vented pole piece, spiders, and magnet cavity . The use of an inverted coil geometry results in a substantial reduction of distortion over conventional loudspeaker systems. Increased linearity over a large excursion is obtained by using dual matched rear suspension components together with the finest quality rubber roll surround. The most unique feature is the use of a flat diaphragm instead of a conical structure. The diaphragm is constructed from a combination of state of the art materials which include carbon fiber and Nomex honeycomb. The result is a diaphragm that is exceptionally stiff and lightweight which does not exhibit cone flex distortion or the buckling effects inherent in conventional designs. Additionally,

PrecisionPower’s

exclusive cast basket design is extremely rigid which ultimately removes any unwanted distortion due to resonance and flexing. Included in this manual are a number of sample enclosure drawings. They are by no means the only enclosures to use, but rather a starting point in the right direction. To determine the correct enclosure for your needs many factors need to be addressed (amount of power, vehicle, placement, crossover, etc.) Therefore, as always, your subwoofer be installed by an
