The new S-Series Speakers have been newly designed with upgrades to voice coil size and cone material to provide great sound quality. The S-Series speakers are the new benchmark for entry OEM upgrades.

Alpine® 4" Coaxial 2-Way Speaker Set

Perfect for an OEM upgrade with many sizes to choose from to suit almost any vehicle

Now available in a 6x9-inch component set, perfect for newer trucks and SUVs

Larger voice coil and new CFRP (Carbon Fiber Reinforced Plastic) cone

Now with Alpine’s patented HAMR (High Amplitude Multi-Roll) Surround, allowing for large amounts of linear air movement

1-inch silk dome tweeter (3/4-inch silk dome tweeter on the S-S40 speaker)

Grilles available for 6x9-inch, 6.5-inch, and 5.25-inch models (grilles sold separately)

S-Series speakers deliver the winning combination of incredible sound and value within an entry-level category.

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.

The 1-inch silk dome is perfect for recreating pleasant upper range response without creating listening fatigue in the vehicle. The soft silk material ensures wide frequency response and durability for long term playback.

Speaker grilles are available for several of the S-Series speakers and are sold separately. The durable mesh grilles are sold in pairs and fit the following models:

6x9-inch models: Compatible with the KTE-S69G Grille

100 mm (4”) woofer featuring a high-quality coated cellulose pulp membrane, combined with peripheral butyl suspension.

Blam 100 RS 2-Way 4" Speaker System

100 mm (4”) woofer featuring a high-quality coated cellulose pulp membrane, combined with peripheral butyl suspension. The generous size of the magnet (70 x15 ) contributes to the achievement of an optimal QTS, a high level of sensitivity and high power handling.The soft dome tweeter features a neodymium magnet and 20 mm CCAW (copper-aluminum alloy) voice coil

in-line 6 dB/oct cross-over ajustable tweeter level : 0 dB or -3 dB

Infinity® Reference 4032CFX 4" Coaxial Car Speaker

New Reference speakers are designed to deliver Infinity’s signature sound in more vehicles. They feature edge-driven textile tweeters for smooth, clear highs and the larger models offer an adjustable tweeter output level control for high-frequency optimization based on installation location or the listener's preference. Oversized Plus One™ woofers offer more surface area for higher bass output and enhanced midrange performance. Plus our newly engineered baskets are optimized to fit most factory speaker locations. Available in a range of standard sizes—3", 4", 5-1/4", 6-1/2", 6" x 8" and 4" x 6" coaxial, 6" x 9" 3-way, and 5-1/4", 6-1/2", and 6" x 9" component—they’re the perfect upgrade from factory speakers.

The audiophile-grade tweeters used in Infinity's new Reference speakers deliver smooth, non-fatiguing sound even at high output levels.

The larger Reference multielement and component systems offer a tweeter output level control to optimize system linearity to suit installation location or the listener's preference.

Harman’s patented (US patent #7,548,631) Plus One™ cones provide more overall speaker-cone area than other cones in its class — the result is higher sensitivity, increased low-frequency output and accurate music reproduction.

Reference speakers are available in a range of standard sizes, and feature a compact design that allows them to fit just about any vehicle on the road today.

Reference speakers provide step-up Infinity sound at mainstream prices.

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.

JL Audio® 4" Coaxial Speaker System

Coaxial Speaker System: 4-inch (100 mm) Woofer, 0.75-inch (19 mm) Silk Dome Tweeter

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.

KFC-1096PS 4" Round 2-way 2 Speaker with a diamond array pattern woofer cone and acoustic sound harmonizer.

Kenwood KFC-1096PS 4" Round 2-way 2 Speaker

This technology enhances sound and reduces distortion.

This unique shape of the tweeter creates strong frontward sound as well as a wider sound field in 5kHz and higher frequencies.

Produces a smooth and natural sound by controlling woofer sound waves and allowing only certain frequencies to pass through the holes of the tweeter panel.

The tweeter height is designed as low as possible, allowing the speakers to easily fit in most factory locations.

By implementing black paint on these parts, heat is released efficiently inside the magnetic circuit, resulting in temperature reduction of the voice coil and improved durability.

Stress leveling points increase durability and provide a smoother sound response.
