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.
Cast Alloy Baskets: The C5-series coaxial speakers feature cast
alloy woofer baskets, while incorporating JL Audio's patented "Elevated Frame" cooling system. This cooling
technology, also found on the flagship ZR component systems and W7 and W6v2 subwoofers, allows air to flow directly
across the top plate and onto the voice coil windings to greatly improve
linearity at all listening levels.
Motor Structure: The DMA (Dynamic Motor Analysis)-optimized motor
structure achieve outstanding linearity.
Woofer Cones: The cone and suspension elements were designed and manufactured
by the world-famous Dr. Kurt Müller & Co of
Germany. The speakers feature low-mass, mineral-filled polypropylene cones with
butyl rubber surrounds. The cone and surround are inherently well damped to
deliver an uncolored, neutral midrange without any coloration. The speakers are
also equipped with symmetrical-roll, hybrid-weave spiders.
Silk Dome Tweeters: The C5 coaxials' 3/4" silk dome tweeters
incredibly smooth on- and off-axis for accurate imaging and a big, stable
Two-way Crossover System: The C5 coaxials utilize the same true
2-way external crossover system found in the C5-series component speakers:
- High Pass: On the tweeters is a second order high-pass filter
utilizing premium Mylar capacitors combined with an air-core inductor. Four
tweeter level settings are selectable via jumper pins: +2.0dB, Reference,
-1.5dB, and -3.0dB.
- Low Pass: The low-pass section features a first order filter with
three levels of user-definable midrange presence: Low, Reference, and High.
Polyswitch: Polyswitch tweeter protection is incorporated into each C5
coaxial crossover network. It monitors current going to the tweeter and will
disconnect the tweeter from the signal when it senses overload. Once the volume
has been reduced, the protection circuit will reset itself automatically.
Barrier Strips: Connections to each crossover network are made via
protected nickel-plated barrier strips.
Dimensions: The C5 crossover systems have the following dimensions:
Width=3.367", Height=4.72", Depth=1.44"
Connection Note: The C5 coaxial speakers come with no speaker wire.
Instead, a number of spade connectors and quick slides are included in the
hardware pack to be crimped onto speaker wire you provide.
