Alpine S-W12D4 S-Series 12″ Subwoofer With Dual 4-ohm Voice Coils


SKU: S-W12D4
Product by:

Great bass requires the best materials and engineering. Alpine’s S-Series subwoofers use advanced technology from higher-end subs to bring your music to life. Also, these subs are an inch shallower than their predecessors, making them ideal for spaces where standard high-power subs won’t fit.
