Alpine S-S40 4" 2-Way S-Series Coaxial Car Speakers

Alpine S-S40 4″ 2-Way S-Series Coaxial Car Speakers

The Alpine S-S40 4″ 2-way car speakers are no exception considering Alpine has been building quality car speakers for decades. If you’ve been living with anemic factory sound, this step up in range, tone definition, and power handling will make you giddy just about every time you hop behind the wheel. And if you’re really jonesing for a boost in sound quality, hook them up to a powerful aftermarket stereo or amp for increased performance. The new cosmetics of the S-Series looks good in nearly any car and their shallow mounting design allows for easy installation in a wide range of door panels. As well, their high-efficiency design can run off of the power from the factory or Alpine head unit, resulting in an easy system improvement for any vehicle.

Alpine’s carbon fiber-reinforced plastic woofer cones provide next-level sturdiness but are also agile enough to handle the complexities of the midrange. Their high amplitude multi-roll rubber surround contributes to reduced distortion for a cleaner sound, while silk dome tweeters give you all the precise details that bring out the character of the instruments and vocals. If you’ve never experienced Alpine sound quality, these speakers are a great place to start.

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.
