Entry level with high end product quality / Match with S-Sub

• S-Series emphasise the line’s sound quality at an entry level. With many sizes availability, these make suitable for various types of vehicles.

CFRP Cone

• The CFRP diaphragm (Carbon Fibre Reinforced Plastic) designed just right between hardness and lightweight position to clear up sound signal and deliver efficient performance. 

HAMR Surround

• The Alpine uniqueness technology H.A.M.R. (High Amplitude Multi-Roll) surround adapted from high end sound system X-Series increasing high output and superb sound quality.

Powerful Speaker Motor

• The voice coin size has been updated into the larger one. The enhancement increases an ability of sound quality, making the sound become more resonant.

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 Fibre Reinforced Plastic), a very lightweight yet rigid material. On a standard, off-the-shelf oval cone, the edges are naturally weaker than the centre due to the elongated shape. Since the CFRP material is directional, it can be manipulated during the moulding 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 moulding process is currently exclusive to Alpine and the S-Series speakers. Alpine has three patent-pending procedures in support of this innovative manufacturing process.

Incredible Linearity And Accuracy

• 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 colourisation rejection.

Smooth, Wide Frequency Response

• 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.
