INTRODUCTION
Your new PowerClass PRO15 Flat Piston subwoofer is part of an exciting line of loudspeakers which represent the extraordinary design achievements of the PrecisionPower Engineering Team.
The PrecisionPower, PowerClass PRO Flat Piston subwoofers have been engineered from the ground up and are constructed at our factory in Phoenix from the finest materials available. Like all PrecisionPower products, they reflect our commitment to “Absolutely State of the Art” performance and flawless sonic quality.
The PRO15 subwoofers incorporate a 5” voice coil, edge wound onto a Black Anodized Aluminum former, 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 vented pole piece, spiders, and magnet cavity. The use of an inverted coil geometry results in a substantial reduction of distortion over conventional loudspeaker topology. 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 consists of a Nomex Honeycomb substrate between two Carbon Fiber skins. 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 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, PrecisionPower recommends that your subwoofer be installed by an Authorized
PrecisionPower Dealer.
