The right driver and the box cut for it, shipped together, with the box 50% off.
Arc Audio subwoofer bundles pair each driver with the Proline X enclosure cut for it, with the box at half price. Choose your sub and the matched enclosure comes locked to it, so there is no guessing on airspace and no wrong box to return. Each bundle ships as one order, the driver plus a box already built to its sealed or ported target, pre-wired and polyfilled, ready to mount and wire. Sealed wedge, shallow Micro, or ported output, there is a pairing for every Arc sub and every install.
Langboard Elite MDF enclosures. 2-Year Warranty. Expert SQ-judge support. Built and shipped from Tullahoma, TN.
CNC-Matched Enclosures
Spec-built to your driver's Thiele-Small parameters
Every bundle is one product: an Arc Audio subwoofer at its regular price, plus the matching Proline X enclosure at 50 percent off. You add one item to the cart and both ship together in a single order. The enclosure is the box we build for that exact driver, so the pairing is done for you. Pick your voice coil, D2 or D4, and you are set.
The discount only exists inside the bundle. On its own the enclosure sells at full price. Buying the sub and box together here is the only way to get the box at half off.
What Is in the Lineup
The lineup pairs every Arc Audio 12 and 10 inch subwoofer, plus the Arc Series 8, with the Proline X box matched to it. The collection fills in by series as each pairing goes live.
X2 Series, sealed and accurate
The X2 is Arc's reference sealed driver, built for tight, accurate bass that blends with the front stage. It pairs with a Proline X Performance sealed wedge, an angled box that holds full sealed airspace while reclaiming trunk space behind the rear seat. The pick for SQ-minded builds in a sedan or hatch.
A-Series, shallow and matched
The A-Series is a true shallow-mount for tight spaces. It pairs with a Proline X Micro Series sealed box, stack-fabricated and cut to the driver's exact sealed target, for full bass in an under-seat or behind-seat footprint.
Arc Series, output and efficiency
The Arc Series steps up motor and power handling and thrives in a ported box. It pairs with a Proline X ported wedge tuned for output, the pick when you want more low-end volume and efficiency from the same amplifier.
SW Series, shallow flagship
The SW shallow-mount runs a front-mounted motor that sits outside the box, so the chamber stays clean. It pairs with a Proline X Micro Series sealed enclosure built to fire down, with the foot kit included, for deep, controlled bass in under-seat and stealth installs.
Why the Box Matters as Much as the Driver
A subwoofer only performs as well as the air it works against. The wrong volume chokes extension or loosens control. The right one lands the driver's intended alignment. Every Proline X box in these bundles is cut from Langboard Elite MDF on our ShopSabre routers in Tullahoma, built to the sealed or ported target for the driver it ships with.
Sealed boxes use either a single-baffle Performance build with V-groove and dado joinery, or a stack-fabricated Micro build cut layer by layer to a true net volume. Either way the box is matched to the sub, not a generic size with a label. That is the point of the bundle: the driver and the air it needs, sorted together. Browse Arc Audio subwoofers or the full Proline X enclosure lineup if you would rather build a pairing yourself.
Frequently Asked Bundle Questions
How does the bundle discount work?
Each bundle is one product: the Arc Audio sub at its regular price and the matching Proline X enclosure at 50 percent off. You add one item, both ship together, and you save the full half-price difference on the box. The enclosure discount exists only inside the bundle.
Does the subwoofer come already installed in the box?
No. The bundle ships the driver and its matched enclosure together in one order, with the box pre-wired and polyfilled and the baffle set with threaded inserts. You mount the driver and connect the wire. If you want it shipped pre-installed, look at the loaded enclosure listings instead.
Can I buy the enclosure at the bundle price by itself?
No. On its own the enclosure sells at full price. Buying the sub and box together as a bundle is the only way to get the box at half off.
Which Arc Audio sub should I choose?
Choose the X2 for sealed SQ accuracy, the Arc Series for ported output, and the A-Series or SW for shallow under-seat installs. Each sub in the lineup is paired with the box that suits it, so once you pick the driver the enclosure is decided.
Is shipping really free?
Yes. Every bundle ships free and insured to the lower 48. A subwoofer plus a wood enclosure is real freight, and we cover all of it. The price you see is the price at your door.
What warranty comes with a bundle?
The Arc Audio driver carries Arc'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.
