About: Open Box - JBL S2-1224SS 12" Slipstream Ported Enclosure (Final Sale Item)

This is a professionally re-certified product. They may or may not include the original manufacturer packaging.

Every unit is thoroughly inspected and tested to ensure it meets the same performance standards as a brand-new product—so you get reliable quality at a great price.

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 enclosure 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 subwoofer feature an exclusive dual impedance switch that lets you choose either load impedance option. Not available from any other manufacture, SSI lets you reconfigure your system by simply flipping a switch. 

High-Roll Surround 

Series II enclosure incorporate a high-roll surround that provides superior cone edge suspension while maximizing excursion. It not only increases the cone area, it also provides remarkable linear stability and reliability. 

Propriety Cone Design

JBL subwoofer cones aren't just built to thump, they're built to last. Series II enclosure feature an exclusive cone design that delivers superior rigidity for long-lasting performance. 

Long Excursion Design

The longer a subwoofer's excursion is, the more air moves. And the more air it moves, the more bass you feel. The long-excursion design in Series II enclosure ensures big, deep bass output. Just the way you like it.
