Alpine 4-Inch Coaxial 2-Way Speakers, 45-Watts RMS The S-Series speakers have a large voice coil. The 6.5-inch and 6x9-inch models have a 35-mm voice coil, and this large voice coil size increases their driving power and control of the motor. The S-Series speakers are the first in the industry to use a material called CFRP (Carbon Fiber Reinforced Plastic), a very lightweight yet rigid material. On a standard, off-the-shelf oval cone, the edges are naturally weaker than the center due to the elongated shape. Since the CFRP material is directional, it can be manipulated during the molding process to strengthen the areas of the cone that are normally weak. The result is rigidity throughout the cone that delivers accurate and efficient performance. The ability to manipulate the CFRP material during the molding process is currently exclusive to Alpine and the S-Series speakers. Alpine has three patent-pending procedures in support of this innovative manufacturing process. Alpine’s patented H.A.M.R. (High Amplitude Multi-Roll) surround is now found on the S-Series speakers. This proven technology increases excursion while maintaining accuracy and linearity. The multi-roll design allows for an even unfolding of the surround which creates incredible linearity and colorization rejection.

C1-Series 4-Inch 35-Watt Coaxial Speaker System C1 speakers deliver real substance and great audio performance in a format designed for easy fit behind factory grilles. To facilitate fit, breakaway mounting tabs on the woofer frame allow the C1-400x to be installed in four-hole or two-hole mounting configurations. C1 woofer drivers benefit from proprietary FEA modeling and JL Audio's expertise in low-frequency driver design. This knowledge is used to create speakers that can play loudly, while maintaining a smooth, dynamic, low distortion sound. At the core of the C1-400x is a proprietary, stamped, steel 4-inch (100 mm) frame and a DMA-optimized motor system. A mineral-filled, injection-molded polypropylene cone is suspended with a rubber surround on the front, and a carefully engineered spider at the top of the voice coil, to precisely control motion and prevent impact between the voice coil and the back plate. Tinsel leads are carefully routed and attached to the spider to prevent fatigue and buzzing. These are the same kinds of features and materials normally found on much more expensive loudspeakers. Equipped with a true, edge-driven, aluminum dome tweeter, C1 speakers stand further apart from others in its category with superior high-frequency clarity and definition. The tweeter’s design has inherently excellent off-axis response and high-frequency extension. It also benefits from the damping of a silk surround suspension and Ferrofluid in the voice coil gap, along with the superior strength of a neodymium magnet circuit. A true, 2nd order high-pass filter is employed to further enhance smoothness and improve power handling. When it comes to value, C1 is the real deal! Sold as a pair. Grilles not available. General Specifications Continuous Power Handling (RMS) 35 W Peak Music Power 105 W Recommended Amplifier Power (RMS) 10 - 50 W / Ch. System Efficiency 84.5 dB @ 1 W / 1 m System Nominal Impedance 4 Ω System Frequency Response 64 Hz - 24 KHz ± 3 dB JL Audio C1-400x Manual

C2-Series 4-Inch 35-Watt Coaxial Speaker System The Evolution C2 systems deliver sparkling high-frequency detail, smooth mid-range and powerful mid-bass, thanks to real silk dome tweeters and precision-engineered woofer designs. The C2-400x system features 4-inch (100 mm) woofers with mineral-filled polypropylene cones, long excursion capabilities and stamped steel frames. The woofer design benefits from JL Audio's vast woofer design experience and advanced modeling systems. Breakaway mounting tabs on the woofer frame allow the C2-400x to be installed in four-hole or two-hole configurations. Injection-Molded adaptor plates are also included to allow mounting of the C2-400x speakers into a 4 x 6 (100 x 150 mm) speaker location. Tweeters are coaxially mounted and built with 0.75-inch silk dome diaphragms that deliver smooth, extended response, on and off axis. The small size of the C2 tweeter minimizes tweeter protrusion, allowing C2 coaxials to fit behind most factory speaker grilles. Speaker grilles are included, each consisting of a black grille tray with satin silver accents and a black steel mesh grille with an electroformed JL Audio logo. Sonic character: Clean and Dynamic Sold as a pair. General Specifications Continuous Power Handling (RMS) 35 W Peak Music Power 105 W Recommended Amplifier Power (RMS) 10 - 50 W / Ch.
