Alpine S-Series 8" 300 Watt RMS 4 Ohm Subwoofer With Dual Voice Coils (S-W8D4)

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.
