Congratulations!
You are the now the owner of an exceptional loudspeaker from the audio enthusiasts at Blaupunkt. Our
engineering staff has spent considerable time refining our ProComponent subwoofers in order to introduce great sound to
the consumer at an affordable price. Now entering our third generation of the PC family of product, we still feature the
rugged design and flexible installation. But now, we have evolved the speaker design with a new polypropelyne cone
material and more aggressive cosmetics.
Not only do we offer you a great product but also a supportive owners manual. This manual can be used as a teaching
guide due to its brief, but informative, explanations of loudspeaker and enclosure design and references to other reading
and computer materials available today. We are also are very concerned about the end consumer using proper installation
techniques for the highest performance possible from their new loudspeakers. MOST important are the concerns with
safety and the installation process. Since our Blaupunkt retail dealers have the tools and experience for an optimized and
safe installation, we always recommend they do the final vehicle integration. But, should you choose to install these
products yourself, please take the time to read this manual completely and abide by all precautions.
It has been repeatedly proven that remarkably high audio system performance can be achieved by moderately priced
components. 90% of all consumers really don’t need $500 woofers with 120 oz magnets for their listening habits. The
PCwg subwoofers are designed for
HIGH POWER HANDLING LEVELS, HIGH SOUND PRESSURE LEVELS,
and
FLEXIBLE INSTALLATION CHOICES.
The focus on our new subwoofers is the vacuum formed polypropylene cone material offering lighter mass compared to
older paper cones but without the flexing properties common to paper. This gives a much “tighter” bass response without
distortions often found at high listening levels. Below is a good summary comparing old cones with the new technologies.
In addition to the vacuum formed poly cones is the expansion of our extended pole program. The extended pole piece of
the subwoofer is lengthened by a few millimeters but the performance results are significant. The non-linear fields around
the voice coil’s gap are greatly reduced thus improved heat dissipation (higher power handling) and increased cone
movement control (higher power but with “cleaner” response).
Vacuum Formed Poly Cones
V A C U U M F O R M E D P O LY
New “VFP” Vacuum Formed Polypropylene Cones
•
Lightweight, and mechanically rigid, poly cones play louder with
less power
•
Acoustically inert, poly cones do not “color” the sound of the music
•
Environmentally resilient poly maintains shape & thickness,
ensuring premium tonal quality for years
Conventional Inexpensive Paper/Plastic Cones
•
Non-uniform cone thicknesses (are heavy & often generate
internal “bending” motions)
•
Self-resonant materials & construction (standing waves occur
yielding strong tonal shifts)
•
Paper & cheap plastic cones warp & change mass over time
due to swings in temperature & humidity (degrading performance)
Speaker Cone
New “EXP” Extended Pole Design
•
Increased cone travel for higher “clean” sound pressure
levels
•
More symmetrical magnetic operating field for lower distortion
•
Better heat dissipation offering higher power handling
capability
Conventional Magnetic Pole Design
•
Limited linear cone travel (high level distortion at lower
volume levels)
•
Uneven magnetic field distribution throughout cone travel
(common distortions)
•
Average heat dissipation (therefore only average power handling)
Extended Pole Design
