Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
C.M.M.D. Plus One
Woofer Cones: These speakers use cones approximately 30% larger than other
speakers of the same size. This is accomplished by using a new basket design and
hi-roll surround. The Plus One design offers greater bass output and a
significant increase in efficiency. In addition, the C.M.M.D. cones virtually
eliminate coloration due to cone flexing, resulting in less distortion and
hi-roll rubber surrounds allow the woofers a greater range of movement,
resulting in longer X-max and more bass output.
speakers come with three different mounting adapters. The adapters allow
the speakers to be installed in a 6-1/2" opening, a 6-3/4" opening, or
an oversized 6-3/4" GM/Chrysler opening.
Materials: Each tweeter features a
1" C.M.M.D. dome that offers superior stiffness and damping compared to
traditional metal domes. Each tweeter is driven by a powerful neodymium magnet,
resulting in higher power handling and superior detail.
Tweeter Mounting System: Surface
mounting involves mounting the surface mount cup (using the supplied screws),
then snapping the tweeter into the cup. Flush mounting is made easy through the
use of the threaded flush mount adapter and plastic locking nut. For flush
mounting, the tweeter is snapped into the flush mount cup. Then, the cup is
secured to the flush mount adapter with a nut and clip washer. Once a cutout is
made, the flush mount adapter (with the tweeter installed) is inserted into the
hole. The large plastic locking nut is threaded onto the adapter (from behind
the mounting surface) to hold the complete assembly securely in place. When
flush mounted, the tweeters may be angled for optimum response and imaging.
There are no provisions for angled surface mounting of the tweeters.
These speakers include computer-optimized, voice-matched crossovers. Each
crossover features an 18dB/octave, 3.5kHz high-pass network for the tweeter and
an 18dB/octave, 3.5kHz low-pass network for the woofer.
Custom Contour: Custom Contour,
if enabled, will reduce the midrange output from the system, resulting in more
perceived bass and high frequency response. In each crossover, this feature is
enabled using the jumper, which is connected directly to the circuit board.
The crossover inputs and outputs are gold-plated screw terminals.
Mounting: There are two
mounting holes in the base of each crossover.
Crossover Dimensions: L=4.251",
