Every layer is cut to the Arc Audio SW12's published sealed targets, with the baffle bored to the SW12's 11-inch cutout and 8\/32 threaded inserts set on the back face for tool-clean machine-screw mounting. The SW12 is a 2.4-inch shallow-mount driver built for deep, controlled bass in tight spaces, and this enclosure is the matched airspace it was designed to live in.\u003c\/p\u003e\n    \u003cp\u003eThe SW12 carries Arc Audio's published Thiele-Small data: Fs of 33 Hz, Qts of 0.616, Vas of 33.73 liters, and an EBP of 45.9, which places it firmly in sealed-enclosure territory. We ran the alignment math on that data and built the box to land it where it belongs. The larger Vas means the SW12 wants more airspace than the SW10 to reach the same Qtc, which is why these boxes run deeper.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"ms-section\"\u003e\n    \u003ch3\u003eOne Footprint, Three Net Volumes\u003c\/h3\u003e\n    \u003cp\u003eAll three sizes share the same 26 by 14.75 inch face. Only the depth changes, so the box keeps the same mounting footprint whether you want the tightest response or the most extension. The volume you select is true net internal airspace, measured after the layered walls, bracing, and driver are accounted for. It is not a gross number with the losses hidden.\u003c\/p\u003e\n    \u003cdiv class=\"ms-grid\"\u003e\n      \u003cdiv class=\"ms-card\"\u003e\n        \u003ch4\u003eMinimum | 0.65 cu ft net\u003c\/h4\u003e\n        \u003cp\u003e26 x 14.75 x 5.25 in.

A separate 4-foot kit is included so you can lift the enclosure off the floor when you mount it down-fire, which sets the gap the cone loads against, couples the bass into the chassis, and protects the driver face. Install the feet when you run it down-fire, leave them off when you do not. It also works front-fire as a secondary orientation if your space calls for it, so the same box covers both installs.\u003c\/p\u003e\n    \u003cp\u003eThe SW12 helps here because its N42UH neodymium motor sits outside the sealed air volume. In a down-fire box that motor lives in the open cavity between the baffle and the floor rather than crammed inside a hot, sealed pocket, so it gets free airflow on every excursion. It also means the net airspace stays true, since the motor is not stealing volume from inside the chamber. We do not mill a magnet-relief pocket the way we do on rear-motor drivers, because there is no rear motor to relieve. The chamber is clean, sealed, and built only for the cone.\u003c\/p\u003e\n    \u003cdiv class=\"ms-highlight\"\u003e\n      \u003cp\u003e\u003cstrong\u003eTrue net, not marketing net.\u003c\/strong\u003e Internal volume is calculated by summing each CNC-cut layer's opening.

Instead of butt joints or dado cuts, the box is stack-fabricated: each layer is a precision-cut ring, and the stacked layers do the joining themselves. The result is a continuous, void-free wall with no seam to flex or leak.\u003c\/p\u003e\n    \u003cdiv class=\"ms-grid\"\u003e\n      \u003cdiv class=\"ms-card\"\u003e\n        \u003ch4\u003eRadiused, Not Boxy\u003c\/h4\u003e\n        \u003cp\u003eAll four corners are radiused 3 inches viewed top-down.

Loaded builds are available in both the SW12 D2 and SW12 D4 coil configurations, selectable by variant.
