JBL S2-1024SS Series II 10 Inch Subwoofer with SSi Selectable Impedance - 2 or 4 Ohm - Open Box

Series II enclosures deliver the enhanced efficiency and higher output of a vented enclosure, without the distracting noise or “chuffing” generated by a port. The patented Slipstream port dramatically reduces port noise at high sound pressure levels by minimizing airflow turbulence. With high-roll surrounds, proprietary cone design and long-excursion, Series II enclosures deliver deep, powerful bass, with greater accuracy than conventional ported boxes. And the exclusive SSI™ (Smart Selectable Impedance) switch lets you choose 2- or 4-ohm impedance for maximum configuration flexibility. It’s everything you want in a compact, easily installed enclosure.

Slipstream port design - At high sound pressure levels, air flow turbulence inside a vented enclosure’s port can create noise that sounds like woofer break up. The patented Slipstream port in Series II enclosures uses a double-flared design to minimize turbulence, and eliminate unwanted vortices.

SSI™ (Selectable Smart Impedance) - Most car audio system designs call for 2- or 4-ohm impedance. Series II subwoofers feature an exclusive dual impedance switch that lets you choose either load impedance option. Not available from any other manufacturer, SSI lets you reconfigure your system by simply flipping a switch.
