Arc Audio A10 Subwoofer

Arc's A-Series shallow-mount 10: 250 watts RMS from just 3.77 inches of mounting depth. A heat-pressed poly-injected pulp cone, Totoku copper voice coil on a Nomex former, a progressive Nomex-blend spider, and a stamped steel basket that holds up face-up, face-down, or at any angle. Built for under-seat, behind-seat, and spare-tire-well 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. Arc rates it sealed, in a 0.4 to 0.9 cubic foot range, and this bundle ships the balanced 0.6 middle.

Why This Works

Arc rates the A10 for sealed enclosures in a 0.4 to 0.9 cubic foot range, and 0.6 is the balanced middle: enough air for clean extension, tight enough to keep the shallow-mount driver controlled. That is the alignment this bundle ships.

This is not a generic 10 box with a label. Every layer is cut to the A10's sealed target and the baffle is bored to its exact 9-3/16 inch cutout, so you get a true 0.6 cubic foot net, not a gross number with the losses buried. The area behind the motor is milled for magnet clearance and voice coil cooling, matched to this driver.

It ships pre-wired, polyfilled, and ready to bolt in. The A10's stamped basket holds up mounted face-up, face-down, or at an angle, so this box drops into an under-seat, behind-seat, or spare-tire-well build without a second thought.

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 A10 in this bundle. The sub stays at its regular 329.00 dollars, the enclosure drops from 269.99 to 134.99, so the bundle is 463.99 instead of the 598.99 combo retail. You save 135 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 0.6 cubic foot Micro Series enclosure is 269.99. 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 A10 subwoofer in the voice coil you select, and one Proline X Micro Series 0.6 cubic foot sealed enclosure in plush black, pre-wired with 12 gauge OFC and polyfilled. 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 A10?

Yes. Arc Audio recommends a sealed enclosure between 0.4 and 0.9 cubic feet for the A10, and this bundle ships the balanced 0.6 cubic foot size. It is a true net volume, cut to the A10's sealed target and bored to its exact cutout.

What warranty comes with the bundle?

The Arc Audio A10 carries Arc Audio's 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.
