Overview

Our take on the JL Audio C3-600

The C3-600 component system uses a 6-1/2" mica-filled polypropylene woofer that covers the midrange and low frequencies strongly and accurately. A specially designed frame resists unwanted resonances, keeping your music free from interference. If you mount the tweeter separately, simply install a phase plug into the woofer and the sound will disperse smoothly throughout your vehicle.

Convertible speaker system

Versatile speaker system for any space

JL Audio's Evolution C3 speaker systems allow you to choose the best configuration for great sound in your vehicle. Mount the woofers and tweeters separately, and a C3 component system will fill your car with incredibly detailed, rich, and crystal-clear music, perfectly positioned in your listening space. In vehicles with limited space, you can mount the C3 tweeter inside the woofer to create a full-range, coaxial speaker that still performs with breathtaking impact.

Advanced material construction leads to clean musical reproduction

The C3-600 component system uses a 6-1/2" mica-filled polypropylene woofer that covers the midrange and low frequencies strongly and accurately. A specially designed frame resists unwanted resonances, keeping your music free from interference. If you mount the tweeter separately, simply install a phase plug into the woofer and the sound will disperse smoothly throughout your vehicle.

Silk tweeters and versatile crossover networks

The C3 tweeters use ferrofluid cooling to handle extreme levels of high-frequency information without overheating. Mounted separately or coaxially, these 1" silk dome tweeters broadcast crisp musical detail evenly without harshness. Separate outboard crossovers use premium components to direct the signal flow to your woofers and tweeters. You can select from three midrange settings and four levels of tweeter presence to match the speaker system to your listening environment.

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

Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

Sound better than the MLB quart I had before just all around fantastic I love the convertible feature

Product Research

Features

Woofers: The JL Audio Evolution C3-600 convertible component system includes 6-1/2" woofers with injection-molded polymer frames, mineral filled polypropylene cones, butyl rubber surrounds, ferrite magnets, and 1.2" voice coils with Kapton formers. In the center of each cone is a phase plug; the phase plug can be removed and the tweeter mounted in its place to create a coaxial speaker.

Tweeters: The 1" silk dome tweeters are Ferro fluid cooled and use neodymium magnets. Silk is lightweight and great for high frequency extension and efficiency. It is also designed for durability in the extreme automotive environment. Flush mount and surface mount housings are included, along with fixtures to coaxially mount the tweeters to the woofers.

Tweeter Dimensions:

  Frame Diameter Cutout Diameter Mounting Height Mounting Depth
Flush Mount 2.134" 1.875" 0.35" 0.853"
Surface Mount 1.926" Screw holes only 0.885" Screw depth only

Coaxial Mounting: The tweeters can be mounted in the center of the woofers to create coaxial speakers. When the tweeters are mounted to the woofers the speaker is taller; the mounting height increases to 0.8".

Two-way Crossover System: The C3 component system utilizes a 2-way crossover system with Mylar capacitors and air-core inductors:

  • High Pass: third order (18 dB/octave slope); four tweeter level settings are selectable to compensate for mounting location or orientation; +2.0 dB, Reference, -2 dB, and -4 dB
  • Low Pass: first order (6 dB/octave slope)
  • Midrange Presence: there are three settings that affect the amplitude of the upper midrange response, designed to compensate for mounting location or orientation; choose High, Reference, or Low

Tweeter Protection: The crossover network has an electronic tweeter protection circuit built in; it monitors the current and disconnects the tweeter when it senses and overload. The circuit automatically resets once the overload is removed.

Crossover Wiring: The terminal strip will accept bare wire or spade connectors up to 0.32" wide (the included crimp-on spade connectors are 0.255" wide).

Crossover Dimensions:

  • Width: 3.368"
  • Height: 1.425"
  • Depth: 4.75" (plus wire)

Connection Note: The C3 component system comes 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.
