Our take on the JL Audio C5-650

by Buck Pomerantz
JL Audio

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

JL Audio's Evolution™ C5 premium component speaker systems 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.

The C5-650 component system features a pair of silk dome tweeters that broadcast all the musical details without a hint of harshness. JL Audio built the 6-3/4" woofers for extended cone travel so they'll move more air, putting more oomph in your music when the rhythm section kicks in. These woofers use the same patented cooling technology developed for the ZR Series speakers, allowing the C5 speakers to play with a wide dynamic range at all volumes.

The C5 crossovers feature 4-position tweeter and 3-position midrange levels that give you 12 possible adjustment combinations for exceptional control over the final sound.

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.

  • component speaker system includes two 6-3/4" woofers, 2 tweeters, two external crossovers, and two woofer grilles

Woofer Features

Cast Alloy Baskets: The Evolution C5 component 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.

Tweeter Features

Silk Domes: The C5 component system's 3/4" silk dome tweeters are incredibly smooth on- and off-axis for accurate imaging and a big, stable soundstage.

Neodymium Magnets: The small neodymium magnets and small chassis give you excellent tweeter placement flexibility.

Performance: Each pair of C5 tweeters is tested and matched to within 1 dB of JL Audio's reference curve to ensure optimum system performance.

Mounting Options: The tweeters come mounted in JL Audio's RSR mounting system to permit precise angling of the tweeters after installation. There are five available positions for angling the tweeter inside the flush mount. The mounting dimensions are as follows:

  • Mounting Depth: 0.56" (1.67" screw depth)
  • Mounting Height: 0.36"
  • Frame Diameter: 1.758"
  • Cutout Diameter: 1.49"

Crossover Features

Two-way Crossover System: The C5 component system utilizes a true 2-way crossover system:

  • 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 component system crossover system.

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 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.

Superb speakers

Written By Craig, Seattle, WA on Thursday, July 01, 2010
 
I installed a pair of C5 650s into the front factory speaker positions on my Nissan 350Z. Before installing the JL's, I installed a pair of Infinity reference speakers and even though the results were better than the atrocious BOSE factory system, I just wasn't happy with the sound.

When I installed the JL's, I added Dynamat extreme to the doors, ran new Monster speaker wires to the amplifier and I purchased a 3/4" MDF spacer from a recommended company. When I finally fired the JL C5 speakers up, I was BLOWN AWAY by how good they sounded. I was getting crystal clear highs and tremendous mids. (Word to the wise: don't skimp on the installation, these speakers demand a quality setup for maximum effect.)

The levels of separation for the different crossover settings are very noticeable and can be customized to your personal tastes in real time. I ended up setting the mids and trebles to their reference settings since to me, they sounded great that way. Setting the trebles or mids on the crossovers to higher than reference actually hurt my ears.

I absolutely recommend these speakers as your primary fronts. Go with something cheaper in the rears, like the JL C2's, since most of your sound is coming from up front anyway. Top these off with a good subwoofer (I have the JL 10W3V3), and you're golden. Yes, the C5's are expensive, but they're so worth it.

Buy these Speakers

Written By Jim, Phoenix, AZ on Saturday, October 25, 2008
 
Very clean sounding and the range is very good. You will not be disappointed with these speakers. The crossover that comes with the speakers works very well and has some nice features for adjusting the level of the drivers and tweeters independently of each other.

You also might want to consider getting the Dynamat Xtreme 10415 door kit. It eliminated all of my rattles in the door and doesn't stink like the traditional Dynamat.

These will fit in the front doors of an 08 Scion TC. You will just need to build your own mounts. I used 3/4" MDF to make the main shape of the mount and an additional 1/4" MDF ring for just a little more clearance. Clears the window with plenty of room and does not hit the door panel.
