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.

Our take on the JL Audio C3-650

by Buck Pomerantz

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.

Convertible speaker system

Advanced material construction leads to clean musical reproduction

The C3-650 component system uses a 6-3/4" 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 6-1/2" 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.

Highlights:

  • component speaker system includes two 6-3/4" woofers, 2 tweeters, two external crossovers, and two woofer grilles
  • mica-filled polypropylene woofer with butyl rubber surround
  • glass-filled polymer frame with Elevated Frame Cooling
  • 1" silk dome tweeter
  • 2-way external crossover with adjustments for coaxial or separate tweeter placement, and 4-position tweeter level
  • tweeter mounts for separate or coaxial installations included
  • phase plug provided when tweeter mounted separately
  • power range: 25-75 watts RMS (150 watts peak)
  • frequency response: 48-25,000 Hz
  • sensitivity: 90 dB
  • depth: 2-9/16"
  • warranty: 1 year
  • Our 60-day money-back guarantee

    Features

    Woofers: The JL Audio Evolution C3-650 convertible component system includes 6-3/4" woofers with injection-molded polymer frames, mineral filled polypropylene cones, rubber surrounds, ferrite magnets, and 1" 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" 0.25" 0.853"
    Surface Mount 1.926" Screw holes only 0.981" 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 0.775", 0.575" for the tweeter protrusion.

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

    • High Pass: second order (12 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: 1.415"
    • Depth: 4.739" (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.

    Size Classification Note: Crutchfield has traditionally referred to this size speaker as a 6-3/4", while some manufacturers, including JL Audio, call it a 6-1/2". Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.

    C3-C650

    Written By Eddie, Knoxville, IA on Tuesday, April 09, 2013
    Crutchfield Customer Review (What's this?)
     
    Just hooked these up with a Alpine HU and a Fosgate amp and they sound amazing... they have a clean smooth, rich, bassy sound to them, just enough highs to sound great! I have C3-600's in the front doors that sound about the same, together with a JL Audio bass and they create a music experience.. I've done very little adjusting with the head unit EQ and I've just been amazed,, JL Audio makes some incredible speakers.. I can't say enough about them..
    Pros:
    Good rich clean sound.. They just sound great..
    Cons:
    I have nothing here..

    Great when paired with an amp

    Crutchfield Customer Review (What's this?)
     
    I had these installed my a custom shop here in town. Soundsational does excellent work anyone in the Indianapolis area. One of the component sets blew the woofer because i had them running off of the head unit power. Crutchfield immediately sent out a replacement to swap them out, great customer service! I paired these with a JL audio XD600/6 and ran 4 channels to these and the other 2 to the rear speakers. Wow, what a difference. Pair these with a good, clean amp and you are in business.
