Alpine S2-SB10V 10" Halo S-Series Preloaded Subwoofer Ported Enclosure with ProLink

Driver: The Alpine S2-SB10V loaded enclosure features a single S2-W10D4 10", dual 4Ω voice coil subwoofer driver. The new S2-Series driver features an improved voice coil that allows it to handle increased power over previous versions.
Power Handling: The S2-SB10V can handle up to 600W RMS.
Enclosure: The S2-SB10V's ported enclosure design has been optimized for use with the S2-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 S2-SB10V's unique design allows it to be linked to an additional S2-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 2Ω load.
