M10-S ARC A | Single 10" Sealed Subwoofer Enclosure | Built for Arc Audio A10 Single 10" Sealed enclosure

No. This is an enclosure-only product designed for customers who already own or are separately purchasing the Arc Audio A10 in either the D2 or D4 impedance configuration. The enclosure ships pre-wired with the Proline X terminal cup, 8/32 threaded inserts, stainless machine screws, pre-installed polyfill, and rubber feet for downfiring installation.

Arc Audio publishes a sealed enclosure range of 0.40 to 0.90 cubic feet for the A10, with 0.60 cubic feet identified as the optimum. This enclosure delivers exactly 0.60 cubic feet of net acoustic airspace. At this volume the A10's system Qtc lands in the elevated range, producing warm, impactful bass with strong upper-bass presence. This is the sound Arc Audio designed the A10 to produce and it is the volume Arc Audio publishes as optimal.

No. The math customers typically run is: external dimensions of 24" × 14" × 6" minus 3/4" walls on all six sides leaves an assumed internal cavity of 22.5" × 12.5" × 4.5", which works out to roughly 0.73 cubic feet, about 0.13 cu ft larger than the listed 0.60. That math is incorrect for four reasons. First, the front baffle is a double-layer stack-fab build at 1.5 inches thick, not 3/4" (twice the assumed wall thickness on the highest-stress panel). Second, viewed from above, all four corners are radiused at 3 inches.

The radii break up parallel-wall standing wave geometry, produce a finished shape that fits cleanly against vehicle interior surfaces, and remove measurable internal volume from the apparent rectangular cavity. Third, the area directly behind the driver's magnet is precision-milled to allow fine volume adjustment and, more importantly, to maintain open area immediately behind the A10's pole vent so backpressure does not interfere with voice coil cooling airflow. Fourth, the driver itself displaces internal airspace once installed.

Our engineering approach is built on precision. Every CNC-cut layer's individual opening is calculated and summed to arrive at the actual net airspace. No one else in this industry calculates net volume this way. The 0.60 cubic foot figure is exact, not approximate.

The A10 sits between the low-Qts SQ drivers (like the ResoNix GUS-10) and the high-Qts warm-bass daily drivers (like the Alpine RS-W10D4) in the Micro Series lineup. Its Qts of approximately 0.51 produces an elevated Qtc in the 0.60 cubic foot sealed target, which delivers a warm, upper-bass-forward response that suits daily-driver installs without requiring DSP correction. The GUS-10 has a Qts of 0.35 and produces a flat 0.707 Qtc alignment requiring DSP for balanced in-cabin response. The RS-W10D4 has a Qts of 1.19 and produces a strongly elevated Qtc that emphasizes upper-bass punch. The A10 is the middle-ground option: warm and impactful without being aggressive, capable without requiring active processing to sound good.

The Arc Audio A10 is rated at 250 watts RMS with 500 watts peak. Target a monoblock delivering 200 to 250 watts RMS at your final load impedance. For the D2 wired parallel at 1 ohm, an amplifier explicitly rated for sustained 1-ohm operation is required. For the D4 wired parallel at 2 ohms, a standard 2-ohm-stable monoblock in this power range is the correct pairing. Do not significantly exceed 250 watts RMS. The A10 is designed for daily-driver power levels, not competition-level thermal loads.

Yes. Rubber feet for downfiring are included with the enclosure. The A10's standard round mounting flange seals cleanly against the baffle gasket in either orientation. Downfiring in truck cab installs couples bass output with the vehicle floor, which reinforces the low-frequency response and works well with the A10's warm, upper-bass-forward character in this enclosure size.

At 6" total depth, 24" wide, and 14" tall, this enclosure fits behind or under the seat in most full-size crew cab and extended cab trucks including the Ford F-150, F-250, Silverado, Sierra, Ram 1500, and Ram 2500. Seat floor clearance varies by model and trim. Measure the available depth at both the front and rear of the install location before purchasing.

Generic 10" sealed boxes for the A10 are typically built to approximate internal volumes without controlled tolerances, assembled with single-layer panels and glue-only joints, and sold as universal fits across multiple driver models. This enclosure is machined to the A10's specific 9-3/16" cutout diameter, built to Arc Audio's exact published 0.60 cubic foot optimum volume, and uses double-layer stack-fab Langboard Elite MDF panels with dowel reinforcement throughout. The area directly behind the driver's magnet is precision-milled to maintain voice coil cooling airflow, a detail most enclosure manufacturers do not address.

The Proline X terminal cup is pre-wired with 12-gauge OFC internally, and 8/32 threaded inserts (rather than wood screws) mount the driver. Every structural and acoustic element is engineered to hold its precision over the life of the installation.
