The Bundle
The Arc Audio SW12 shallow-mount subwoofer and the Proline X Micro Series enclosure cut for it, sold as one unit. Through the July event the enclosure is 50 percent off, so you get the box at half price and the whole system ships as a single part number. One add to cart, one delivery, one box to unpack.
Pick your voice coil above, D2 or D4. The enclosure is the 0.8 cubic foot Optimum sealed Micro Series, Arc's recommended volume for this driver, cut and built in house in Tullahoma, Tennessee, pre-wired with 12 gauge OFC and polyfilled, with the down-fire kit included.
In The Box
▸One Arc Audio SW12 subwoofer (D2 or D4)
▸One Proline X Micro Series 0.8 cu ft sealed enclosure, plush black, pre-wired and polyfilled
▸4-foot down-fire kit and a 2 year enclosure warranty
Arc Audio SW12 Subwoofer
The flagship of Arc's SW Series: a 2.625 inch shallow-mount 12 with a 3 inch aluminum voice coil, 15.5mm of one-way Xmax, and a front-mounted N42UH neodymium motor that sits outside the enclosure. It beats the JL 12TW3's excursion from nearly an inch less depth, built for under-seat, down-fire, and seat-back installs.
Pick your coil by your amplifier. D2 wires to 1 or 4 ohms for 1-ohm monoblocks, D4 wires to 2 or 8 ohms. The reinforced cellulose cone, low-shore butyl surround, and external motor are built for deep, controlled bass in tight spaces.

Why This Works
The SW12 is a sealed driver by design, its EBP of 45.9 puts it firmly in sealed territory, and at 0.8 cubic feet it lands the alignment Arc recommends. Sealed keeps it tight and accurate, which is the whole point of a shallow, SQ-minded 12.
This is not a generic 12 box with a label. Every layer is cut to the SW12's published sealed targets and the baffle is bored to its exact cutout, so you get a true 0.8 cubic foot net, not a gross number with the losses buried. Because the SW12's motor lives outside the box, the chamber stays clean and the airspace stays honest.
It ships pre-wired, polyfilled, and with the down-fire kit, ready to bolt in. Mount it down-fire and the SW12's external motor breathes free air in the floor cavity instead of cooking in a sealed pocket. Run it front-fire if your space calls for it.
The Bottom Line
This is a fixed bundle, so the box is locked to the sub. There is no wrong enclosure to order by mistake. The box cut for this exact driver, built in house, at half price.
Bundle FAQs
How does the bundle discount work?
The Proline X Micro Series enclosure is 50 percent off when you buy it with the SW12 in this bundle. The sub stays at its regular 629.99 dollars, the enclosure drops from 299.99 to 149.99, so the bundle is 779.98 instead of the 929.98 combo retail. You save 150 dollars, in one add to cart.
Can I buy the enclosure separately at the bundle price?
No. The 50 percent enclosure price only exists inside this bundle. On its own the 0.8 cubic foot Micro Series enclosure is 299.99. Buying the sub and box together as the bundle is the only way to get the box at half price.
What ships with the bundle?
One Arc Audio SW12 subwoofer in the voice coil you select, and one Proline X Micro Series 0.8 cubic foot sealed enclosure in plush black, pre-wired with 12 gauge OFC and polyfilled, with the 4-foot down-fire kit. Both ship together as a single unit from Tullahoma, Tennessee.
Should I choose the D2 or D4 voice coil?
Choose by your amplifier. The dual 2 ohm (D2) wires to 1 ohm or 4 ohms, which suits 1-ohm monoblocks. The dual 4 ohm (D4) wires to 2 ohms or 8 ohms. Both cost the same in the bundle. If you are unsure, tell us your amp and we will point you to the right one.
Is the enclosure the right size for the SW12?
Yes. Arc Audio recommends 0.8 cubic feet sealed for the SW12, and this bundle ships that Optimum size. It is a true net volume, cut to the SW12's published targets, and lands the driver at Qtc 0.972 with F3 at 41.5 Hz.
What warranty comes with the bundle?
The Arc Audio SW12 carries Arc Audio's 1-year warranty through authorized dealers, and Audio Intensity is one. The Proline X enclosure carries a 2-year warranty. You also get lifetime install support from real installers.
