It’s rare to be excited at speakers at this price level however we at Superfi think Alpine have really set a new level on launching the new SS Series. While the price of these is lower than the SPR series the performance is nothing short of it.

Looking at the speaker you will see that the rubber surround is nothing like what you would expect on such a small speaker, usually found on subwoofers, the new design allows for extend bass frequencies. This is very rare for speakers of this size. The cone material has been newly developed by Alpine and we believe is a World’s First use of such material, CFRP (Carbon Fibre Reinforced Pastic) the use of this design gives light-weight combined with extreme strength resulting in clean and powerful bass with accuracy.

Larger than average voice coil size allows for improve power handling, using the same technology as on the competition X Series. Silk Dome tweeter gives the clarity and precision of crystal clear upper frequency without the harshness.

Introducing the S-Series speaker line
The all-new Alpine S-Series speakers offer an amazing price vs. performance ratio and come in many configurations. They are perfect for OEM upgrades with many sizes to choose from to suit a wide variety of vehicles.

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 colorization rejection.

CFRP Cone

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.
