JL Audio CP108LG-W3v3 Slot-Ported Enclosure Engineering

What sets this system apart is the enclosure itself. Extensive internal bracing allows thinner walls while maximizing internal volume. The port wraps around two walls to achieve a low tuning frequency, which improves bass depth and consistency. Flared port openings reduce unwanted air noise, keeping the sound clean even when the bass hits hard.

JL Audio CP108LG-W3v3 Built With Premium Materials

Every detail here feels intentional. The enclosure is crafted from CNC-cut, high-grade MDF using advanced V-groove construction for tight, precise joints. The black automotive-grade carpet finish, accented with silver JL Audio embroidery, gives it a refined look. A steel mesh grille is included to protect the subwoofer while maintaining airflow.

JL Audio CP108LG-W3v3 W3v3 Subwoofer Technology

At the heart of the system is the W3v3 subwoofer, designed for medium-power applications. It uses a mineral-filled polypropylene cone, elevated frame cooling technology, and a vented reinforcement collar to manage heat and maintain reliability. The floating cone assembly and DMA-optimized motor design help ensure smooth excursion and low distortion, even during demanding bass passages.

JL Audio CP108LG-W3v3 Power Handling And Specs
