What exact subwoofer does this fit?
This enclosure is precision-built specifically for a single 6.5" JL Audio® W3v3 micro-subwoofer (model 6W3v3-4). The cutout diameter is perfectly matched at 5.5" (5-1/2").
Will it fit in my vehicle?
Yes, it is engineered for extreme space savings and hidden installations. The ultra-compact, space-saving external dimensions are an incredibly tight 8.5" W x 8.5" H x 6.25" D, making it easy to tuck under seats, inside center consoles, or behind panels.
How is the performance and wiring?
This sealed design delivers exceptionally tight, responsive, and musical low-end accuracy (with a smooth 0.7548 Qtc alignment). It features an upgraded 2" round nickel-plated binding post for secure and reliable wiring connections.
OEM-Spec™ Enclosures: Purpose-Built for JL Audio®
Dropping a premium JL Audio® subwoofer into a cheap leaky box is a quick way to leave performance on the table. Our LAB OEM-Spec™ enclosures aren't trying to reinvent the wheel. Instead, they are precision-built tools manufactured right here in the USA to do exactly what JL Audio® intended.
We construct these with rock-solid CNC-cut MDF to support your drivers. These enclosures follow JL Audio’s exact volumetric blueprints to the letter. By utilizing their highly efficient smaller-airspace designs, you get two very practical benefits. You get increased mechanical power handling to keep your sub safe from over-excursion, and you gain a significantly smaller footprint in your trunk.
Available in both ported and sealed configurations for most JL Audio® drivers, the OEM-Spec™ line delivers the accurate, hard-hitting bass JL is famous for at a price point that actually makes sense.
