Product Information

Enclosed Subwoofer System with Single 8W3v3-4 Subwoofer Driver, Black Carpet (250 W, 4 Ω) - Ported Enclosure

 CP108LG Product Spotlight

This incredible MicroSub™ subwoofer system delivers the kind of output and extension that is normally possible with only much larger systems. The key to its performance lies in the precise tuning of its 8W3v3 subwoofer driver into an efficient slot-ported design.

Extensive interior bracing permits the use of thinner wall material that maximizes the enclosure's internal volume relative to its exterior volume. The port wraps around two walls of the enclosure to produce the necessary low tuning frequency that ensures excellent extension and response smoothness. The flared port entry and exit further enhance sound quality by minimizing air-flow noises through the port.

This subwoofer system is shipped wired, loaded and ready to connect via a five-way binding post terminal.

Finish: Black, high-grade automotive carpet with silver "JL AUDIO" embroidery on front baffle. A steel mesh grille is included to protect the subwoofer driver.
