What exact subwoofer does this fit?
This enclosure is precision-built specifically for a single 8" JL Audio® W3v3 subwoofer (model 8W3v3-4). The cutout diameter is perfectly matched at 7.09" (7-3/32").

Will it fit in my vehicle?
Yes, it is designed to maximize output while maintaining an incredibly small, space-conscious footprint. The exact external dimensions are a compact 10" W x 10" H x 9.5" D.

How is the performance and wiring?
This sealed design delivers exceptionally tight, snappy, and responsive low-end accuracy (with a highly musical 0.783 Qtc alignment and an F3 of 54Hz). 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.
  •        
  • Heavy-Duty Construction: 100% 3/4” CNC-cut MDF with ultra-thick front baffles on select models for maximum structural integrity.
  •        
  • American Made: Designed, cut, and assembled in the USA for strict quality control.

My dogs favorite
Size: Small, Color: Bunny
I need this toy! It is my dogs favorite. She even takes this on walks. Ive replaced this on 3 times because it was “eaten” by my daughters dog. I keep it put up and Georgia constantly goes to the spot I keep it and is expecting me to give it to her. Please restock soon

My doggo's go-to toy!
It's not the most durable of toys (she's on her third in five years) but I will buy her as many as she needs because she is OBSESSED with it!

Defective toy and inconsistent quality.
Size: X-Large, Color: Raccoon, Size: X-Large, Color: Raccoon
My initial review was 5 stars based on my experience with a previous order (blue raccoon) and the fact my puppy was immediately interested in it. However, I did not give it to her to play with until this past Friday (May 21, 2026) because she had the first one I bought. In a matter of 2 days the seam on the back and at the base of the head unraveled and all of the stuffing was scattered all over the room. I thought I’d found some good, high quality, toys for her but apparently this one was defective because the first one had had a lot of use and I’d still in decent shape. This is too much money to pay for a dog toy that only lasts a day or two so be advised they aren’t all good.

Bigger, louder, crinklier, softer, than expected!
Size: X-Large, Color: Rabbit
My dog was gifted a collection of used toys and he really likes a very long stuffed pig which, unfortunately, another dog that is a destructive chewer, totally destroyed. I decided to break down and buy him another long stuffed toy today and since he's always blissfully watching rabbits in the yard and neighborhood I chose the rabbit version. This thing is huge which is great for him- he's 62 lbs and 7 months old and only half grown. He loves it, it has multiple LOUD squeakers, lots of crinkly spots, and fun ears/legs to grab hold off. He's a big fan and it's made with K9 Tuff Guard which LASTS. Super soft and easy to wash. Update after 2 months- easy to wash and looks new after a washing. very durable so far, standing up to indoor and outdoor use. He is not a destructive chewer but whips them around, tramples on them, steps on them while running top speed and chomps on the annoying squeaker for hours. one squeaker has a hole and its tune is now slightly muted (thank god)
