JL Audio Enclosures by Size and Alignment
The widest brand range we cut, spanning both alignments and every orientation. Use this for the shape of it, then match the model named on the product page.
| Size | Orientations | Alignments | Series |
|---|---|---|---|
| 10 inch | Standard, wedge, down-fire | Sealed and ported | Performance Optimized, Micro, Vehicle Specific |
| 12 inch | Standard, wedge, down-fire | Sealed and ported | Performance Optimized, Micro, Professional |
| 13 inch | Standard and wedge | Sealed and ported | Professional, Performance Optimized |
Shared across every row: Langboard Elite MDF cut on ShopSabre routers in Tullahoma, Tennessee. Plush black carpet. A Proline X ABS and carbon fibre composite terminal cup with stainless hardware, pre-wired in 12-gauge OFC. Construction method varies by series and is stated on each product page.
One Badge, Several Very Different Drivers
A shallow-mount JL and a large-format JL of the same stated diameter have almost nothing in common but the badge. Their parameters, their mounting depths and the cabinets they need all differ. Work from the model number on your driver rather than from the size, because here it matters more than on any other brand page.
Buy the Box, and Sometimes the Driver
We stock a shallow-mount JL driver alongside these enclosures and several cabinets ship loaded with the driver already fitted. We do not carry the wider JL line, so for most models you source the subwoofer elsewhere and buy the cabinet here. Either way we build to the same published figures.
Performance Optimized Series
The bulk of the JL range. Cut to one driver on a 1.5 inch double baffle, across every orientation we build.
Cut to one driver
Micro Series
Cut around a depth budget for the shallow-mount JL drivers, where a standard cabinet simply will not fit the opening.
Cut to one driver
Vehicle Specific and Professional
Cabinets cut to a named vehicle, and heavier builds for the large-format drivers that justify the extra cabinet.
Cut to one driver
Baffle thickness and construction method vary by series. Each product page states how that cabinet is built and which JL Audio model it was cut for.

Read the guideJL Audio Subwoofer Box Questions
Which JL Audio subwoofers do these boxes fit?
The range covers JL Audio drivers in ten, twelve and thirteen inch across their shallow-mount, standard-depth and large-format lines. Each product page names the exact model its cabinet was cut for, and that is the match to work from rather than the nominal size.
Why is this range so much bigger than your other brand pages?
Because JL builds more distinct kinds of subwoofer than most manufacturers. A shallow-mount driver and a large-format flagship need genuinely different enclosures, so the range spans both alignments, three orientations and four build standards to cover them properly.
Do you sell JL Audio subwoofers?
We stock a shallow-mount JL driver alongside these enclosures. We do not carry the wider JL line, so for most models you would source the driver elsewhere and buy the cabinet here.
Are these sealed or ported?
Mostly sealed, with a ported group for the drivers built for that loading. Every sealed cabinet ships with polyfill already installed. Ported cabinets need more airspace than sealed ones for the same driver.
What is the difference between Micro and Performance Optimized?
Micro Series cabinets are the shallow-space builds, cut around a depth budget for openings a standard cabinet will not fit. Performance Optimized cabinets are cut to one driver on a 1.5 inch double baffle where there is more room. Both work from the same published driver data.
Do you make direct-fit JL boxes for vehicles?
Yes. Some of these are Vehicle Specific cabinets cut to a named vehicle and year range rather than to a generic opening, and several of those ship loaded with the driver already fitted.
