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 4
Ω
and 8
Ω
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
