This enclosure holds 0.75 cu ft net per chamber. In it the Arc Audio ARC Series 10 runs a system Qtc of 0.69–0.74 with half power at 40.9–43.2 Hz, and the cone reaches its 15.0 mm travel limit at 247 W, below the driver’s 250 W thermal rating, so travel is what stops you here, not heat. Run a subsonic filter at 25 Hz and that becomes 344 W — +97 W, or 40 percent more power for the same 15.0 mm of travel.

01Is it a sealed driver?

Efficiency bandwidth product places the motor before anything else is decided.

EBP = Fs ÷ Qes = 51.6–55.2
SEALED 0–50 TRANSITION 50–100 PORTED 100–150 0 50 100 150 D2 55.2 D4 51.6
D2 · EBP 55.2D4 · EBP 51.6
At 51.6–55.2 the ARC Series 10 sits in the transition band, not the sealed band. That is not a mismatch: a transition motor works in either alignment, and sealed buys a smaller box and a gentler roll-off at the cost of some low-end output. Stage 02 shows what this airspace actually does with it.

02What the box does to it

0.75 cu ft against a 45.8 L Vas.

α = Vas ÷ Vb = 2.15  ·  Fc = Fs√(α+1) = 42–43 Hz  ·  Qtc = 0.69–0.74

D2 · Qtc 0.69, Fc 42 Hz, F3 43.2 HzD4 · Qtc 0.74, Fc 43 Hz, F3 40.9 Hz
The box lifts resonance from 23.8 Hz free-air to 42–43 Hz and half power lands at 40.9–43.2 Hz, anechoic, before any cabin gain. This enclosure ships without a driver, so both coil variants the maker offers are plotted. They do not load the same box the same way.

03The watts that reach Xmax (in this enclosure)

Travel scales with the square root of power, so there is one wattage that puts the cone exactly on 15.0 mm — and a bigger one once a subsonic filter stops it wasting travel below the passband.

PXmax = 247–249 W unfiltered  →  344–362 W with a 25 Hz subsonic
20 30 50 70 100 150 200 0 4 8 12 16 FREQUENCY · Hz CONE TRAVEL · mm PAST LINEAR TRAVEL · Xmax 15.0 mm 247 W reaches Xmax here

Every trace touches the limit and no further, because each is drawn at the exact power that puts that coil on 15.0 mm. Unfiltered that is 247 W, reached first at 20 Hz. It sits under the 250 W the driver can take thermally, so the enclosure sets the ceiling, not the voice coil. The dashed traces are the same driver behind a subsonic filter at 25 Hz, 24 dB/oct: stopping the cone wasting travel below the passband lets it take 344 W before hitting the same 15.0 mm. That is 40 percent more amplifier for the price of one filter setting.

Installer's take

The Arc ARC Series 10 is one of Arc Audio's most versatile drivers. Not their flagship, that's the X2v2, and not their shallow-mount problem-solver, that's the A10, but the daily-driver workhorse that gets the job done cleanly and reliably in the largest number of real installs. If you're building a system where a single 10 is the right cone size (compact car, stealth trunk build, integration with a full-range front stage that doesn't need heavy midbass reinforcement), the ARC 10 is a strong pick. The 0.75 cubic foot volume in this box is the reason it works. Arc specifies 0.65 cubic feet as the minimum, 0.85 as the optimum, and 1.1 as the SPL-oriented volume. 0.75 sits between minimum and optimum, dialed toward the tighter, more musical side of the driver's range. You get transient response that keeps up with quality midbass, low-end extension that integrates cleanly, and a Qtc that lands where SQ-oriented builds want it. If you were chasing pure peak SPL, you'd push closer to 1.0 cubic feet. For a driver that's supposed to disappear into the music, 0.75 is right. The 8.25-inch cabinet depth is worth calling out. The ARC 10's 5.5-inch mounting depth means there's roughly 2.5 inches of internal clearance behind the magnet inside this cabinet. Enough for adequate magnet ventilation, not so much that airspace is wasted. Some generic 10-inch boxes run 10 inches deep or more, which starts pushing internal volume above 1.0 cubic foot even in a compact footprint. This cabinet is sized correctly for the driver, not oversized to hit a spec sheet. Wiring is straightforward. Dual 2-ohm gets you 1 ohm parallel or 4 ohms series. Dual 4-ohm gets you 2 ohms parallel or 8 ohms series. The 250-watt RMS rating means you don't need a massive amp, a clean 250 to 300 watt monoblock at your chosen impedance is the target. Arc's own XD Series or Mini Series in that range are the ideal match. Any quality monoblock stable at your load will also get you there. For a single 10 sealed build with an SQ-oriented lean, this is the box the ARC 10 was built for. -Scott
