S-SB12V - Alpine 12 600W RMS 2-Ohm Subwoofer Vented Box. Alpine has been pumping out great sound for over 40 years, and now their Halo Series subwoofer enclosures make it easier to add more bass to your system.You'll get the low end you're looking for from one box, but when you want to expand your system, you can add a second enclosure and the optional linking kit to create a single two-speaker system with double the impact. The S-SB12V comes loaded with Alpine's S-W12D4 subwoofer wired for 2-ohm impedance. The sub's Kevlar-reinforced cone and Santoprene surround give you solid bass response at power levels up to 600 watts RMS. The ported enclosure is tuned to 35 Hz to maximize performance. Heavy-duty steel front and rear linking brackets connect the enclosures for a compact, sturdy dual-subwoofer solution. The silver linking brackets match the enclosure trim for a neat, coordinated look. Loaded with Alpine's S-W12D4 subwoofer. Kevlar-reinforced pulp cone with Santoprene rubber surround. Dimensions: 17"W x 14-5/8"H x 15D. Ported enclosure loaded with one S-W12D4 subwoofer driver. Rubber flange protector (installed on subwoofer). You will be issued a Return Authorization Number.
