Industry First CFRP Woofer Cone

The S-Series speakers set an industry first, utilising CFRP (Carbon Fiber Reinforced Plastic), a very lightweight yet rigid material. On an ordinary oval cone, the edges are naturally weaker than the center due to the elongated shape. However, CFRP material is directional, and 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.

Alpine HAMR Surround

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 an even unfolding of the surround, which creates incredible linearity and colorisation rejection.

Powerful Speaker Motor

The S-Series speakers are undeniably powerful, featuring a large voice coil. The 6.5-inch models have a 35-mm voice coil, at such a large size, this incredible voice coil increases the driving power and control of the motor.

Grilles to Protect Your Speakers (Sold Separately)

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