S-S40 - 4" (10 cm) Coaxial 2-Way Speakers
The S-Series delivers amazingly high performance for this class of speaker. They boast the world’s first use of a CFRP diaphragm (Carbon Fiber Reinforced Plastic), which has the ideal balance of hardness and light-weight, for extremely clean and accurate sound. They also feature a larger voice coil than previous types for higher driving power, and the same HAMR surround as used on the X-Series.
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.
