Alpine S-Series 4 Coaxial 2-Way Speaker Set – S-S40

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.The S-Series speakers have a large voice coil. The 6.5-inch and 6×9-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.RMS Power Handling: 80 Watts Peak Power Handling: 240 Watts.H.A.M.R. (High Amplitude Multi-Roll) surround is now found on the S-Series speakers..H.A.M.R.’s multi-roll design allows for an even unfolding of the surround which creates incredible linearity and colorization rejection..First in the industry to use a material called CFRP (Carbon Fiber Reinforced Plastic). a very lightweight yet rigid material..CFRP material can be manipulated during the molding process to strengthen the areas of the cone that are normally weak.
