Description

The JL Audio CP108LG-W3v3 is a compact MicroSub system engineered to deliver significant bass output without requiring a large footprint. Ideal for vehicles with limited space, this enclosed subwoofer system integrates an 8-inch W3v3 subwoofer into a precisely tuned, slot-ported enclosure to achieve impressive low-end response and smooth bass extension. The enclosure itself is a testament to thoughtful engineering, utilizing extensive internal bracing to allow for thinner walls while maximizing internal volume. The slot port is strategically wrapped around two enclosure walls to achieve a low tuning frequency, enhancing bass depth and consistency. Flared port openings are incorporated to minimize unwanted air noise, ensuring clean audio output even during demanding bass passages. Built with premium materials, the enclosure is crafted from CNC-cut, high-grade MDF with advanced V-groove construction for robust and precise joints. It is finished in a durable black automotive-grade carpet and accented with silver JL Audio embroidery. A protective steel mesh grille is included to safeguard the subwoofer while maintaining optimal airflow. At the core of the system is the W3v3 subwoofer, designed for medium-power applications. It incorporates a mineral-filled polypropylene cone, elevated frame cooling technology, and a vented reinforcement collar for reliable heat management. The floating cone assembly and DMA-optimized motor design contribute to smooth excursion and reduced distortion, ensuring high-fidelity bass performance. This system is ready to connect, shipped wired and loaded, featuring five-way binding post terminals.
