Product Description

Features & Specifications




JL Audio CP108LG-W3v3 8″ 250 Watt 4 Ohm Subwoofer #93133

This incredible CP108LG-W3v3 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 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.

Engineered for performance

JL Audio’s CP108LG-W3v3 MicroSub enclosed subwoofer system delivers impressive bass without needing a lot of power or taking up much space. This MicroSub handles up to 250 watts RMS, housing one 8″ W3v3 subwoofer that offers impressive low end. The enclosure is designed from the ground up to get optimum performance from its driver, so you get much more than just a box with a speaker inside.

JL Audio uses state-of-the-art automated woodworking equipment to fabricate the high-quality MDF enclosure with rugged automotive carpeting, a steel-mesh grille, 5-way binding posts, and solid internal wiring. The enclosure is finished and inspected by hand at the manufacturing facility in Florida to ensure that you get the bass that you expect from JL Audio.

Small enclosure, big sound

The specially designed, slot-ported enclosure measures just over 6-1/2 inches thick, so it’ll fit just about anywhere. Its flared slot-port design cuts down on air turbulence and keeps your bass rich and clear. You’ll enjoy thick low-frequency response from all of your music with this capable enclosure in your vehicle.
