Features Driver:?The Alpine S-SB10V loaded enclosure features a single S-W10D4 10", dual 4? voice coil subwoofer driver. The new S-Series driver features an improved voice coil that allows it to handle increased power over previous versions. The high strength frame is designed to withstand the rigors of the new S-Series motor. Frame leg vents and a vented back plate help keep the sub driver running cool. The driver also features two strontium ferrite magnets stacked together for increased motor strength and excursion. Both 4? voice coils are wired in parallel for a single 2? connection. Power Handling:?The S-SB10V can handle up to 600W RMS. Enclosure:?The S-SB10V's ported enclosure design has been optimized for use with the S-W10D4 driver, and has been tuned to 36Hz for deep, powerful bass. It features a rigid, heavy-duty MDF construction that's been wrapped in attractive black carpet, with a smooth black finish and silver trim on the front face.? Enclosure Linking (Optional):?The S-SB10V's unique design allows it to be linked to an additional S-SB10V (sold separately) using the optional?KTX-H10?linking kit. This features an aluminum rear link-plate and an attractive, steel-reinforced ABS front linking bracket that securely locks the two enclosures together. Terminals:?A single rear-panel terminal cup houses a pair of binding posts for connection, accepting up to 12 ga. speaker wire. Both of the driver's voice coils are wired in parallel for a single 2? load. Specifications: Driver:?Single 10" Impedance:?2?
