Components in order to introduce a series of subwoofer
unparalleled value in
the car audio market. The PC performance standards were increased yet we were able to drive
the speaker costs down using improved manufacturing techniques and high technology
materials.
In addition to improved performance, the quality standards have been increased substantially.
A car may see temperature extremes ranging from -40” to nearly 200” F driving from Minnesota
to Arizona. Because of these extremes, our engineers subject their designs to long-term
temperature, humidity, and vibration testing to ensure product life spans exceeding that of most
cars.
This manual is composed of several sections and offers brief discussions in each area.

can be achieved with value conscious components. Simply
speaking, 95% of the car audio subwoofer installations
made today really don’t need $400
woofers with 100 oz magnets! The PC series woofers were designed for HIGH POWER
HANDLING LEVELS, HIGH SOUND PRESSURE LEVELS, and FLEXIBLE INSTALLATION
CHOICES.
HIGH POWER HANDLING was achieved
through a new ultra-linear long-throw
suspension with “bottomless” back plate
design allowing for tremendous cone
excursion without voice coil damage. The
new rigid spider design (Blaupunkt
trademarked as “SPIDERMAX”) renders
spider tears a thing of the past. Double
thickness compressed foam surrounds offer
linear cone movement without tearing from
over-excursion. New Strontium Ferrite
magnets yield smaller magnet sizes without
reduced magnet strength but retain their
magnetic power far beyond the expected life
of the woofer. Four layers of wire on DuPont
n Polyamide voice coil bobbins with
allow for voice coil temperatures
exceeding nearly 400” Fahrenheit without damage. New basket designs prevent the back of the
cone from slapping the steel frame thus avoiding acoustical distortions and possible cone
damage. Rear vented pole plates allow fresh air to move in from behind the woofer to cool the
voice coil plus help prevent dust cap “popping” at the excursion limits.
