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 external dimensions are 14.5" W x 10.125" H x 5.25" D, making it easy to fit into tight storage compartments or behind panels.

How is the performance and wiring?
This micro vented/ported design is tuned optimally to 38Hz to deliver surprisingly deep, rich bass output down to 34.92Hz (F3) from a tiny footprint. 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.

  • Factory-Tuned Precision: Built exclusively to JL Audio® factory specs for optimal Thiele/Small (T/S) parameter matching.
  •        
  • Heavy-Duty Construction: 100% CNC-cut high-grade MDF for maximum structural integrity in a micro footprint.

Nice and Simple - but big
Style: 4-Tier Shelf Brackets, Hardware Only.
Nice product, very simple in reality. All screws together. Shelves are probably 12inches high - higher than I wanted so I won't be using it after all - but that is my fault for not realizing how vertically spaced the shelves would be. The unit takes up a lot of vertical wall space. My only dislike (hence the -1 rating) is the large stamped letters on every wall mounting plate. The letters don't appear to mean anything, and are very large and upraised - to me they detract from the overall appearance of the unit. The letters are not possible to get rid of without a grinder or significant file-work and repainting everything (not worth the significant effort that would entail).
