What exact subwoofer does this fit?

Will it fit in my vehicle?
Yes, it is designed to maximize output while maintaining a very compact, cube-style footprint. The exact external dimensions are 16.625" W x 16" H x 16" D.

How is the performance and wiring?
This sealed design delivers exceptionally tight, responsive bass and clean low-end accuracy (with an F3 of 37.7Hz)—ideal for sound quality (SQ) focused systems. 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 3/4” CNC-cut MDF and feature 1” or thicker front baffles on select models to support heavier motors. 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.

        

Why It Hits the Mark:

   
           
  • Factory-Tuned Precision: Built exclusively to JL Audio® factory specs for optimal Thiele/Small (T/S) parameter matching.
  •

Just Ok.

They look nice but they aren’t sturdy and do not hold much weight. I’ve bought better ones on Amazon.

Worth
Size: 6 pcs: 15.7*5.7, Color: White
Really good wall amounts. I used the drywall anchors and it feels sturdy. I put like a 3 pound Crystal on it and it’s holding perfectly fine. I also was able to paint them with no problem would buy again.

Great quality
Color: Rustic Brwon, Size: 16in
Hassle but they work great. I love the color, the thickness and quality. They do have some weight but in my opinion, I prefer that. Right now the four shelves are holding up my WiFi routers and remotes. Will buy again

Good quality shelves
Color: Walnut, Size: 24in, Color: Walnut, Size: 24in
These shelves are gorgeous in person. Yes, they're darker than the listing pics, but I actually prefer it. The grain is beautiful, they came well-packed, and mounting them was no trouble at all. Now I've got display space that feels both stylish and practical. Definitely worth it!
