C3 Convertible Component Systems
There are times when an installation calls for a separate woofer and tweeter and other times when a coaxial is the better approach. With the new Evolution™ C3 Convertible Component Systems, the same product can be deployed in either configuration, delivering outstanding audio quality in both.
Creating this product required an entirely new woofer chassis design with carefully engineered architectural features. Our engineers specified an extremely strong, glass-filled polymer to form the new baskets via an injection molding process. This allows for even tighter mechanical tolerances than a cast alloy basket and also results in a low resonance, non-magnetic mounting structure. JL Audio’s patented Elevated Frame Cooling technology is also built in to improve the woofers’ heat dissipation and power handling.
Inside these new baskets is a potent woofer design using oversized (1.2-inch diameter) voice coils for enhanced power handling and reduced thermal compression. Long coil winding lengths create a very wide dynamic envelope in which linear behavior is maintained, reducing distortion and improving bass capability. C3 woofer cones are precisely shaped to control response and reduce undesirable breakup characteristics and employ high-grade butyl rubber surrounds and Conex® spiders for years of reliable, high-fidelity performance.
The C3 tweeter is a true, edge-driven 1-inch (25mm) silk dome that excels on or off axis and offers very smooth and flat frequency response to well beyond 20 kHz. Silk is an ideal tweeter diaphragm material thanks to its light weight, strength, inherently good damping characteristics and environmental stability. These benefits combine to deliver very good efficiency, smooth response and sparkling high frequency detail without the harshness common in many competitive products. Driving this silk dome is a powerful motor using high-temperature grade neodymium and ferroluid-cooling for superior efficiency and long-term fidelity.
The tweeter is built onto a carrier that can be mounted with a simple twist into a flush or surface mount fixture (for separate mounting applications), or onto the woofer’s pole piece, when used as a coaxial. When the tweeters are mounted separately, phase plugs are provided to mount onto the woofers. Since the tweeter’s coaxial wiring connections are done from the front of the C3 woofer, it is possible to convert a C3 from one mode to another while the woofer is mounted in the car.
Specifically-designed, true 2-way outboard crossovers with premium capacitors and inductors are included with each system. These include adjustments for coaxial or separate tweeter mounting, plus four adjustable tweeter levels. The C3-525 and C3-650 include front-loading protective grilles with black steel mesh and electroformed logo nameplates that can be positioned on the grilles or elsewhere in the vehicle, according to the needs of the installation.
