Spec Sheet

Series II enclosure 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 enclosure 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.

Series II Enclosure 12" Slipstream™ ported enclosure Features and Benefits What’s in the Box 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 doubleflared design to minimize turbulence, and eliminate unwanted vortices. 1 ported enclosure SSI (Selectable Smart Impedance) Most car audio system designs call for 2- or 4-ohm impedance.
