A W3 and a W7 want different net volumes, and a TW3 wants a different cabinet entirely because of its mounting depth. We build a different series against each.\u003c\/p\u003e\n\n\u003ch3\u003eW0, W1 and W3: Performance Series\u003c\/h3\u003e\n\u003cp\u003eThe workhorse end of the JL range. Performance Series enclosures cover the 10 inch at $219.99 and the 12 inch at $249.99, cut to the net volume those drivers were designed around rather than a generic box that happens to fit the cutout.\u003c\/p\u003e\n\n\u003ch3\u003eW7 and W7AE: Professional Series\u003c\/h3\u003e\n\u003cp\u003eThe W7 is JL's flagship and gets the Professional Series treatment: the 10w7 at $399.99, the 12w7 at $479.99, and the 13w7 in a ported build at $599.99. These are the boxes to pair with a driver at that price point, where a mismatched cabinet costs you the performance you paid for.\u003c\/p\u003e\n\n\u003ch3\u003eTW3: Micro Series\u003c\/h3\u003e\n\u003cp\u003eThe TW3 is JL's shallow mount line, so it needs a shallow cabinet rather than a scaled down standard one. Micro Series boxes cover the 10TW3 at $249.99 and the 12TW3 at $269.99, built with stack fab construction so the walls stay rigid at a reduced external footprint. We stock the \u003ca href=\"https:\/\/audiointensity.com\/products\/jl-audio-10tw3-d4\"\u003e10TW3-D4\u003c\/a\u003e and \u003ca href=\"https:\/\/audiointensity.com\/products\/jl-audio-12tw3-d4\"\u003e12TW3-D4\u003c\/a\u003e drivers if you need both halves.\u003c\/p\u003e\n\n\u003caside class=\"ai-callout-spec\"\u003e\n\u003cp class=\"ai-callout-label\"\u003eQuick Reference: JL Audio Enclosure Mapping\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"ai-spec-key\"\u003eW0 \/ W1 \/ W3:\u003c\/span\u003e Performance Series\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"ai-spec-key\"\u003eW6:\u003c\/span\u003e Performance Optimized, built to spec\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"ai-spec-key\"\u003eW7 \/ W7AE:\u003c\/span\u003e Professional Series\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"ai-spec-key\"\u003eTW3 shallow mount:\u003c\/span\u003e Micro Series\u003c\/p\u003e\n\u003c\/aside\u003e\n\n\u003ch2\u003eShallow Mount and Depth Limits\u003c\/h2\u003e\n\n\u003cp\u003eMounting depth is the constraint that decides most JL builds, particularly in trucks and under seats. The TW3 exists precisely because a standard W series driver will not physically fit in those spaces, and dropping a shallow driver into a full size box wastes the advantage you paid for.\u003c\/p\u003e\n\n\u003cp\u003eIf you are working to a depth limit, measure the space before choosing the driver rather than after. A Micro Series box plus a TW3 will fit places a W3 and a standard cabinet will not. If you have the room, the W series in a matched box will generally give you more for the money.\u003c\/p\u003e\n\n\u003ch2\u003eLoaded Option\u003c\/h2\u003e\n\n\u003cp\u003eOne build in this range ships loaded: a Micro Series 10 inch with the JL Audio 10TW3-D4 already mounted and wired, at $699.99. That covers the gasket seal and coil wiring at our bench rather than in your driveway. Everything else here ships as a box only, prewired to the terminal cup and ready for the driver you supply. If you want a loaded build in a configuration we do not list, we can assemble one.\u003c\/p\u003e\n\n\u003ch2\u003eHow These Are Built\u003c\/h2\u003e\n\n\u003cp\u003eLangboard Elite 3\/4 inch MDF, CNC cut on ShopSabre routers in Tullahoma, Tennessee. Internally braced, prewired to a Proline X ABS and carbon fiber terminal cup with stainless steel hardware. Sealed variants ship with polyfill installed.\u003c\/p\u003e\n\n\u003cp\u003eWarranty follows the series. Professional Series and Micro Series enclosures, which covers the W7 and TW3 boxes, carry a 2 year limited warranty on craftsmanship and materials. Performance Series enclosures, which covers the W0, W1 and W3 boxes, carry 1 year.\u003c\/p\u003e\n\n\u003cp\u003eNet volume is calculated from each driver's published Thiele Small parameters.

The W7 in particular is unusually specific about the cabinet it wants, which is why it gets its own Professional Series build rather than sharing a box with the rest of the range.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between the TW3 and the W series?\u003c\/h3\u003e\n\u003cp\u003eThe TW3 is JL's shallow mount line, designed for installs where mounting depth is limited such as behind or under a seat. The W series is standard depth. They are not interchangeable in the same enclosure, because the shallow driver needs a shallow cabinet to be worth choosing in the first place.\u003c\/p\u003e\n\n\u003ch3\u003eDo you sell JL Audio subwoofers as well as the boxes?\u003c\/h3\u003e\n\u003cp\u003eWe stock the 10TW3-D4 and 12TW3-D4 shallow mount drivers. For W series drivers we build the enclosure and you source the sub, or contact us and we will point you in the right direction.\u003c\/p\u003e\n\n\u003ch3\u003eDo you build for the 13W7?\u003c\/h3\u003e\n\u003cp\u003eYes. The 13w7 gets a ported Professional Series enclosure at $599.99. It is the largest driver in the W7 line and the ported alignment suits it where the space allows.\u003c\/p\u003e\n\n\u003ch3\u003eShould I buy the box loaded or empty?\u003c\/h3\u003e\n\u003cp\u003eEmpty if you already own the driver, which covers most of this range. One loaded build is listed, a Micro Series 10 inch with the 10TW3-D4 mounted and wired. If you want another configuration loaded, we can assemble it before it ships.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need an amplifier?\u003c\/h3\u003e\n\u003cp\u003eYes. These are passive enclosures with no amplification built in. For a single subwoofer a monoblock matched to the driver's final impedance is the standard approach. Keeping the factory head unit also means adding a line output converter or a DSP with speaker level inputs.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the warranty?\u003c\/h3\u003e\n\u003cp\u003eIt depends on the series. The W7 boxes are Professional Series and the TW3 boxes are Micro Series, and both carry a 2 year limited warranty on craftsmanship and materials. The W0, W1 and W3 boxes are Performance Series and carry 1 year. The JL Audio driver itself carries its own manufacturer warranty separately.\u003c\/p\u003e\n\n\u003c\/div\u003e","products":[{"product_id":"proline-x-performance-optimized-enclosure-for-jl","title":"Proline X - Performance Optimized Enclosure for JL 12 W0\/W1\/W3","description":"\u003cp\u003eThe Proline X Performance Optimized Enclosure is revolutionizing the way you experience audio.

JL Audio's published ported recommendation is 2.375 cu ft. This enclosure delivers 2.5 cu ft net — close to spec with a small addition of breathing room appropriate for this driver's Vas of 3.68 cu ft — tuned to 33Hz to prioritize low-frequency extension and SQ-focused output character over peak SPL efficiency.\u003c\/p\u003e\n \u003cp\u003eThe 42.5 sq in port area is sized to move the air volume this driver displaces at Xmax without generating port noise at sustained high power. This is not a shelf-queen build — it is engineered to perform correctly under the load of 1500 watts RMS into a 13.5\" driver with 32mm of one-way linear excursion.\u003c\/p\u003e\n \u003c\/div\u003e\n\n \u003cdiv class=\"ps-section\"\u003e\n \u003ch3\u003e1.5\" Double-Layer Baffle — Twelve-Point Mounting System\u003c\/h3\u003e\n \u003cp\u003eThe 13W7AE mounts via twelve bolt positions around its flange — a pattern JL Audio engineered specifically to distribute clamping force evenly across the largest mounting footprint in the W7 lineup. This enclosure's 1.5\" double-layer baffle — two full sheets of Langboard Elite MDF bonded and CNC-cut as one unit — provides the rigidity and thread depth that twelve-point mounting demands. Threaded inserts are installed through the baffle matched to the 13W7AE's #10-32 bolt pattern. Metal-to-metal threading. No wood screw holes to strip. No mounting hardware to chase after a loud session.\u003c\/p\u003e\n \u003c\/div\u003e\n\n \u003cdiv class=\"ps-section\"\u003e\n \u003ch3\u003eDado + V-Groove Joinery | Extensive Internal Bracing\u003c\/h3\u003e\n \u003cp\u003eAt 32\" wide and 17.75\" deep, this is a large enclosure carrying a 52-lb driver at 1500 watts RMS. Panel integrity is not optional. Every joint is CNC-cut to interlock — dado joints recess each panel into its mating surface, V-groove cuts at panel edges create a mechanical lock — and extensive internal bracing ties opposing walls and spans panel runs across the full enclosure volume.

Those numbers tell you exactly what this driver needs from its enclosure: a sealed box in the 0.50 cubic foot range produces a system Qtc near 0.88 — a slightly elevated damping curve that gives the 10TW3 the extension and transient control it was designed to deliver in compact sealed installs.\u003c\/p\u003e\n    \u003cp\u003eGeneric \"universal\" thin-box enclosures are built to an approximate size and sold across multiple driver models. Internal volume tolerances are loose, joints are glued without mechanical locking, and the panel mass is rarely sufficient to stay acoustically inert at high excursion levels. This enclosure is built to a defined spec for one driver. Internal volume is held to within 0.01 cubic foot. Every panel joint is CNC-cut for a mechanical dado fit before adhesive is applied. The result is a box that behaves the way the modeling says it should — consistently, from unit to unit.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- SECTION 2: Stack Fab Construction --\u003e\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003eStack Fab Construction — Why Depth Is Not the Enemy\u003c\/h3\u003e\n    \u003cp\u003eThin enclosures have a structural problem that standard-depth boxes don't: less panel depth means less rigidity, which means more panel resonance. The Proline X Micro Series addresses this directly through stack-fab layering — CNC-cut MDF panels are layered and bonded in overlapping orientations so that no glue joint runs the full depth of any critical wall. The result is a high-mass, mechanically locked enclosure that resists flex at the panel level, not just at the corners.\u003c\/p\u003e\n    \u003cp\u003eEvery interior dimension is machined to maintain 0.50 cubic feet of net internal volume after accounting for driver displacement, terminal hardware, and polyfill.

The baffle carries the driver's mechanical mounting load and sustains the full acoustic pressure differential between the sealed interior and exterior on every bass transient. At 400 watts RMS on a 12\" cone, a single 3\/4\" panel resonates at frequencies within the driver's operating range. Two bonded layers eliminate that coloration at the structural level.\u003c\/p\u003e\n    \u003cp\u003eThe rest of the enclosure uses CNC-cut interlocking dado joints at every panel intersection — mechanical interlock before adhesive, adhesive seal after. Neither alone is the joint. The 6.75\" total depth gives each side panel more inherent geometric rigidity than the ultra-shallow Wavtech builds in the same series, which means the dado joinery here is reinforcing an already more rigid structure rather than compensating for shallow panel depth.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- WHY CARDS --\u003e\n  \u003cdiv class=\"ms-card-grid\"\u003e\n\n    \u003cdiv class=\"ms-card\"\u003e\n      \u003cspan class=\"ms-card-label\"\u003eVolume\u003c\/span\u003e\n      \u003ch4\u003e0.80 cu ft Net — JL Audio's Published Optimum\u003c\/h4\u003e\n      \u003cdiv class=\"ms-card-divider\"\u003e\u003c\/div\u003e\n      \u003cp\u003eJL Audio specifies \u003cstrong\u003e0.80 cubic feet\u003c\/strong\u003e as the optimum sealed volume for the 12TW3.

That Qts sits at the edge of sealed and ported territory — and while the driver performs well in either alignment, ported is the correct call when output and low-frequency extension are the priority. JL Audio publishes 1.75 cu ft as their ported recommendation. This enclosure delivers 2.25 cu ft net — a deliberate step above JL's minimum, sized to complement the driver's Vas of 2.33 cu ft and produce a lower, smoother tuning response at 33Hz rather than a peaked output curve.\u003c\/p\u003e\n    \u003cp\u003eThe 26 sq in port area is calculated to handle the air displacement this driver generates at Xmax without port compression or chuffing at sustained power levels.

That Qts sits above the typical ported threshold — this driver will perform in either sealed or ported alignment — but ported is the right call when the goal is extracting the 10W7AE's full low-frequency potential and output capability. JL Audio publishes 1.5 cu ft as their ported recommendation. This enclosure delivers 1.7 cu ft net — sized above JL's minimum to give the driver more breathing room relative to its Vas of 1.28 cu ft and produce a smoother, more extended low-frequency response at 33Hz.\u003c\/p\u003e\n    \u003cp\u003eThe 22 sq in port area is calculated for the air displacement this driver produces at 23mm one-way Xmax at 750W. Port sizing at this enclosure volume keeps air velocity in check and eliminates port noise at sustained output levels. Small enclosures with undersized ports are where 10\" ported builds typically fail — this one doesn't cut corners on port area.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"ps-section\"\u003e\n    \u003ch3\u003e1.5\" Double-Layer Baffle — Twelve-Point Mounting System\u003c\/h3\u003e\n    \u003cp\u003eThe 10W7AE-3 uses the same twelve-point #10-32 bolt pattern as the rest of the W7AE family. This enclosure's 1.5\" double-layer baffle — two full sheets of Langboard Elite MDF bonded and CNC-cut as a single unit — provides the rigidity and thread depth that twelve-point mounting demands. Threaded inserts through the baffle, metal-to-metal threading throughout. No wood screws into MDF. No hardware working loose under sustained vibration.

Every joint in this enclosure is CNC-cut to interlock before adhesive is applied. Dado joints recess each panel into its mating surface. V-groove cuts at panel edges create a mechanical lock independent of glue. Extensive internal bracing ties opposing walls and spans panel runs throughout the cabinet. The airspace stays constant, the port geometry doesn't shift, and the bass that comes out of the port is what the driver put in — not a distorted version of it.\u003c\/p\u003e\n\n    \u003cdiv class=\"ps-card-grid\"\u003e\n      \u003cdiv class=\"ps-card\"\u003e\n        \u003cspan class=\"ps-card-label\"\u003eMDF\u003c\/span\u003e\n        \u003cdiv class=\"ps-card-divider\"\u003e\u003c\/div\u003e\n        \u003ch4\u003eLangboard Elite 3\/4\"\u003c\/h4\u003e\n        \u003cp\u003eMill-certified panel stock. \u003cstrong\u003e48.5 lbs\/ft³ density\u003c\/strong\u003e, \u003cstrong\u003e200 psi internal bond\u003c\/strong\u003e, \u003cstrong\u003e410,000 psi MOE\u003c\/strong\u003e.
