Performance Optimized Down Fire Wide Sealed 10" Enclosure Arc Audio ARC 10 · Single 10" Sealed enclosure

Because it is only 12 inches deep. The standard Performance Optimized Down Fire cabinet for the ARC Audio ARC 10 is 30 wide by 15 deep, and this version is for spaces 3 inches shallower than that, under a rear bench or on a narrow cargo floor.

Airspace has to come from somewhere. Losing depth means recovering it along the length, so the cabinet runs 41 inches long and stands 7 inches tall. If you have 15 inches of depth, the standard cabinet is shorter in length and is the better pick; if you have 12 inches of depth and 41 inches of run, this is the shape that works.

Same driver, different shape. The standard cabinet is 30 by 15 by 7.125 inches and was built to 1.00 cubic feet net. This cabinet is 41 by 12 by 7 inches and holds 1.053 cubic feet net.

The wide cabinet holds a little more air because its height is set by the ARC 10's 5.5 inch mounting depth rather than by a volume target. Both boxes are motor limited; the choice between them is the space you have. The standard box is deeper and shorter, this one is long and shallow.

Because the driver is physically taller than the box Arc's volume produces. The ARC 10 mounts 5.5 inches deep, and the cabinet needs 0.75 inch of clearance above the motor, which sets the height at 7 inches.

At that height the 41 by 12 footprint holds 1.111 cubic feet gross and 1.053 net. The resulting alignment is Qtc 0.621 with F3 at 43.9 Hz on the Dual 2-Ohm, more damped than Arc's figure would give. Extra air lowers Qtc, which is the safe direction.

Gross. Arc Audio labels every recommended enclosure volume in their manual as gross, for both sealed and ported designs, which is a less common convention than net and worth understanding before you compare their numbers to anyone else's.

Gross volume is the raw internal airspace before the driver and bracing are subtracted. Arc publishes the ARC 10's displacement at 0.05 cubic feet. Every volume we quote on this page is stated explicitly as gross or net, 1.111 gross and 1.053 net, so the two cannot be confused.

Arc Audio rates the ARC 10 at 250 watts RMS continuous with 500 watts musical, and lists an amplifier power range of 5 to 500 watts. The RMS figure is the recommended continuous power; the driver handles roughly twice that in short bursts, and sustained operation above the RMS rating will burn the voice coil and is not covered under warranty.

Arc also notes that underpowering is not what kills subwoofers, clipping is. A modest amplifier driven cleanly is safer than a large one driven into distortion. Both versions are dual voice coil, so set the final load at the driver.

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.

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 keeps the cabinet airtight under sustained pressure cycling. A windowed U-brace, dadoed to the shell, ties the long walls together across the 41 inch span. The front baffle is a double layer at 1.5 inches, two bonded 3/4 inch sheets with the outer layer machined as a flush recess. Polyfill is installed as a light wall lining. Assembled and inspected in Tullahoma, Tennessee.

No. This listing is for the enclosure only. Bring your own ARC Audio ARC 10 in either coil configuration. The cutout and mounting depth are cut specifically for this driver, and the alignment figures are given for both the Dual 2-Ohm and the Dual 4-Ohm.
