Rather than just heari
ng a blurry
wall of music, you can expect
to hear stages like the

…
Here are s
o
me 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 wh
y the center of t
he soundstage will not
be in the center of the vehic
le… When speakers get further
away from you, you become more
centered. Let’s take another
look at the first picture. Fo
r easy
math, we’r
e going to assume
that the left speaker is
4’ from
the left ear in the lower door cor-
ner. The right speak
er is 6’ wh
ich 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 t
he right speaker is on
ly 7’ away. We just reduced
our pathlength

Common Features
Amongst
All 3 Drivers
Motor
Assembl
y
These unique motors use ultra strong Neo- dymium magnets which help to yield high the BL required for great tr
ansient response. (No
huge, impractical standard Ferrite magnets that are har
d
to fit in some applications!)
Voice Coil &
Terminals
All voic
e
coils use 2-layer copper clad
aluminum wire for higher power handling and heat dissipation.
Suspen
sion
The multi-roll Cone
x spid
ers (not on tweeters)
are symmetrical in design and has woven tin- sel leads t
o
the voice coil. The surrounds are
made of high-loss Butyl rubber. This mar- riage of our chosen suspension component
s
allows the driver to be very taut and accur
a
te
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.
