Our take on the JL Audio C5-650x

by Buck Pomerantz
JL Audio

Why replace your factory speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

JL Audio's Evolution™ C5 premium full-range speakers reproduce your music with impressive fidelity and power. Your music will sound smooth and balanced, from the splash of a cymbal to the thump of an electric bass, and everything in between.

JL Audio's C5-650x 6-3/4" speakers feature long-excursion woofer cones that travel farther and push more air than normal woofers, putting more oomph in your music when the rhythm section kicks in. The frame assembly utilizes a patented cooling system, which increases efficiency, power handling, and long-term reliability. The fluid-cooled silk dome tweeters combine with the woofers to create a well-defined and stable soundstage, almost like having a live band inside your vehicle.

Unlike most full-range speakers, these Evolution™ C5 speakers use external crossovers that feature 4-position tweeter level and 3-position midrange presence controls. You can tailor speaker output to suit your listening preferences and to compensate for your vehicle's acoustics.

Note: JL Audio describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.

Crossover Features

Features

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 are incredibly smooth on- and off-axis for accurate imaging and a big, stable soundstage.

Crossover Features

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.
