JL Audio CP108LG-W3v3 Ported Single Subwoofer Enclosure 4Ω

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.

Construction: CNC-Cut High-Grade MDF

Recommended amplifier power: 100 - 250W

Nominal Impedance: 4 Ω

I heard two of these in a 95 single cab Chevy and I was blown away by how much bass they provide. These sound better than my two 12 inch Rockford fosgate r2 subs in my single cab Colorado. If you want something small that produces great bass get these subs. I promise they won't let you down.

Installed in the back of my 09 Nissan 370Z. This box provides excellent bass you feel. It’s compact and light, perfect for a sports car. Teamed up with a JL Audio Slash 250 1v2 mono block amp, provides ample sound for my tastes.
