Larger voice coil and new CFRP (Carbon Fiber Reinforced Plastic) cone.
Alpine s s65c upgrade#
(High Amplitude Multi-Roll) surround is now found on the S-Series speakers. Alpine has three patent-pending procedures in support of this innovative manufacturing process.Īlpine’s patented H.A.M.R. The ability to manipulate the CFRP material during the molding process is currently exclusive to Alpine and the S-Series speakers. The result is rigidity throughout the cone that delivers accurate and efficient performance. 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. On a standard, off-the-shelf oval cone, the edges are naturally weaker than the center due to the elongated shape. 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. 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 have a large voice coil. The S-Series speakers are the new benchmark for entry OEM upgrades. The new S-Series Speakers have been newly designed with upgrades to voice coil size and cone material to provide great sound quality.
The versatile speaker upgrade with incredible sound tech.
