Precision Power PC3.65C Car Stereo System User Manual


 
Rather than just hearing a blurry wall of music, you can expect
to hear stages like the illustration below…
Here are some basic drawings of common problems in a typical
vehicle…
In this 1st picture, it is easy to see why the speaker closest to
you will be louder and why the center of the soundstage will not
be in the center of the vehicle… When speakers get further
away from you, you become more centered. Let’s take another
look at the first picture. For easy math, we’re going to assume
that the left speaker is 4’ from the left ear in the lower door cor-
ner. The right speaker is 6’ which is 50% further and yields a
24” pathlength difference. If we moved both of those speakers
up about 2’ into the kickpanel, the left speaker may now be 6’
away, but the right speaker is only 7’ away. We just reduced
our pathlength
Driver Anatomy
The new raw drivers found in the PC3.65 and PC2.65
component sets encompass elite technologies and allow
us to bring you some of the finest components ever built.
Common Features Amongst All 3 Drivers
Motor
Assembly
These unique motors use ultra strong Neo-
dymium magnets which help to yield high the
BL required for great transient response. (No
huge, impractical standard Ferrite magnets
that are hard to fit in some applications!)
Voice Coil &
Terminals
All voice coils use 2-layer copper clad
aluminum wire for higher power handling and
heat dissipation.
Suspension
The multi-roll Conex spiders (not on tweeters)
are symmetrical in design and has woven tin-
sel leads to the voice coil. The surrounds are
made of high-loss Butyl rubber. This mar-
riage of our chosen suspension components
allows the driver to be very taut and accurate
from the midbass range to upper midrange
frequencies.
Basket
Injection-molded PPS (Polyphenylene Sul-
fide) was used to lower resonance frequen-
cies. If you drop a metal ruler and a wooden
ruler, the metal ruler has horrific "ping" reso-
nance while the wooden ruler has a dead
"thud" sound. Since baskets can’t be made
out of wood for durability reasons, this com-
posite material was the proper way to go.
