Fits in Most Common Applications

To meet the needs of the most common applications in speaker replacement today, we’ve introduced a new 6x9-inch component set to offer newer domestic trucks and cars the ability to upgrade the sound quality in their vehicle. This component set with its innovative technology makes it a simple solution to getting Alpine sound in many of these vehicles on the road today.

Increased Driving Power and Control

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.
