Performance Optimized Down Fire Sealed 10" Enclosure | Arc Audio SW10 Single 10" Sealed enclosure

2.4 inches of mounting depth, or 2.25 inches if front-loaded. That is the shallowest driver in the entire Proline X Down Fire program. For comparison, most drivers marketed as shallow-mount 10s sit between 3 and 3.5 inches. The enclosure built around it stands 5.0625 inches tall overall, which puts it within reach of under-seat spaces that will not accept anything else.

Because of the driver's free-air resonance and compliance, and both are the direct cost of a 2.4 inch mounting depth. The SW10 has an Fs of 39.3 Hz and a Vas of 12.96 liters, so predicted F3 in this cabinet is 45.9 Hz. Drivers that reach into the low 30s carry deeper motors and more compliance, and they need more mounting depth to do it. This is a genuine engineering tradeoff rather than a shortcoming: if your install has the clearance for a deeper driver, take one. If it does not, the SW10 delivers a properly damped, controlled alignment in a space nothing else fits.

Not for the enclosure alignment. Arc publishes full Thiele-Small data for both configurations and the two are nearly identical: Fs 39.3 Hz series versus 39.0 parallel, Qts 0.624 versus 0.634, Vas 12.96 versus 13.33 liters. This cabinet is correct for either. Choose your wiring based purely on what impedance your amplifier is stable and efficient into.

Because Arc Audio publishes their sealed enclosure recommendations as gross volume rather than net, which is unusual. Most manufacturers state net volume, meaning the airspace remaining after the driver's displacement is subtracted. Arc states total internal volume before displacement. We built this cabinet to 0.604 cubic feet gross to match Arc's published 0.6 gross optimum, roughly 0.55 net. Both figures appear in the specifications so you can compare against either convention.

Side mounted. Every Proline X Performance Optimized enclosure uses a side mounted terminal cup regardless of alignment, whether standard, wedge, or down fire. On this cabinet that keeps the connection fully accessible with the enclosure in its installed position, since the baffle faces the floor. The cup is our Proline X ABS and carbon fiber composite unit, recessed, with stainless hardware, copper ring terminals, and pre-wired 12 gauge OFC.

Down Fire cabinets are built with square corners as a series standard. The 3 inch top down corner radius used on other Proline X alignments does not apply here. A down fire box is a low, wide platform that sits flat against a floor or under a seat, and square corners maximize usable internal volume for a given footprint while keeping the cabinet stable on its mounting surface.

V-groove and dado joinery, CNC-cut on ShopSabre routers from Langboard Elite MDF. Every panel joint is a machined interlocking groove that mechanically locks the panels before adhesive is applied, which is what keeps the cabinet airtight under sustained pressure cycling. The front baffle is a double layer at 1.5 inches, two bonded 3/4 inch sheets. On a cabinet this short the baffle carries a large share of the structural load, since there is minimal room for bracing geometry. Perimeter cross-bracing and pre-installed polyfill complete the build. Assembled and inspected in Tullahoma, Tennessee.

No. This listing is for the enclosure only. Bring your own Arc Audio SW10 in either dual 2 ohm or dual 4 ohm. The cutout and mounting depth are direct fit for either version.
