Alpine S-Series 12" 600 Watts RMS 2 Ohms Subwoofer with Dual Voice Coils (SW12D2)

The new S-Series speakers replace the previous Type-S models. The larger voice coil and new cone material of the S-Series speakers emphasize the line’s sound quality at an entry level price. The S-Series speakers are the first in the industry to use a material called CFRP (Carbon Fiber Reinforced Plastic), a lightweight yet rigid material that delivers accurate and efficient performance. Alpine’s patented HAMR (High Amplitude Multi-Roll) Surround is now found on the S-Series speakers, allowing for large amounts of air movement with unmatched control and accuracy.

• Kevlar-Reinforced Pulp Cone
• The woofer features a High Amplitude Multi Roll Surround (HAMRS)
• Dual Voice Coils
• Alpine recommends a sealed enclosure with an internal volume between 0.61 and 1.06 cubic feet, with an ideal volume of 0.85 cubic feet.
