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
20 30 50 70 100 150 200 +6 +0 -6 -12 -18 -24 FREQUENCY · Hz LEVEL · dB −3 dB
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

Dual 10s versus a single 12 is one of those debates that never really settles. Both work. Both have installs where they're the right call. But for a lot of daily-driver SQ builds, and specifically for the Arc ARC Series 10, a properly matched pair of 10s is often the better answer than the single 12 people default to. Here's why. Two Arc ARC 10s give you roughly 40% more total cone area than a single ARC 12. More cone area at the same SPL means each driver moves less, which means less distortion, less thermal load, and less mechanical stress on the suspension. On real music at real volumes, that translates to a system that sounds cleaner and stays cleaner as the session goes on. The transient response is the other thing worth talking about. A 10-inch cone has meaningfully less moving mass than a 12-inch cone. Less mass means faster acceleration and deceleration in response to the input signal. Kick drums start and stop cleanly. Bass guitar has articulation. The handoff to your midbass drivers around 60-80 Hz feels natural instead of soft. This is the reason serious SQ competitors so often run dual 10s instead of a single 12, the speed of a 10 with the output of a 12. The 1.5 cubic foot common chamber is what makes the pair work. Arc's spec for the ARC 10 is 0.65 minimum, 0.85 optimum, 1.1 SPL-oriented. 1.5 total for the pair puts each driver at 0.75 effectively, between minimum and optimum, dialed toward the SQ side. That's exactly where an ARC 10 wants to live if you're chasing musicality over raw peak SPL. If you want more extension and more output at the cost of some transient tightness, you could push the total to closer to 1.7 cubic feet. But 1.5 is the SQ-oriented sweet spot, and it's what this box delivers. The 28-inch cabinet width is also worth noting. That footprint fits behind most SUV third-row seats and in mid-size sedan trunks without eating the cargo bay. At 10.5 inches deep, the box sits closer to the trunk wall than the 12" dual version does, which matters when you're trying to keep useable trunk space. Pair this with a clean 400-500 watt RMS monoblock at your chosen impedance and you've got a genuinely serious system in a footprint that doesn't demand the whole trunk. -Scott

Questions

What size enclosure do two Arc Audio ARC Series 10 subwoofers need?

Two Arc Audio ARC Series 10 subwoofers perform best in a 1.5 cubic foot net sealed enclosure. The Audio Intensity Performance Optimized Dual Sealed 10 for Arc Audio ARC 10 delivers exactly 1.5 cubic feet net internal volume in a common chamber, giving each Arc ARC 10 effective access to 0.75 cubic feet of airspace, between Arc Audio's specified 0.65 minimum and 0.85 optimum sealed volume per driver, dialed toward the SQ side.

What are the dimensions of the Performance Optimized Dual Sealed 10 enclosure for the Arc Audio ARC 10?

The Performance Optimized Dual Sealed 10 enclosure for the Arc Audio ARC 10 measures 28" wide x 14" tall x 10.5" deep externally. Net internal volume is 1.5 cubic feet in a common-chamber configuration, with a maximum mounting depth of 10 inches behind each baffle.

How much power can two Arc Audio ARC Series 10 subwoofers handle?

Two Arc Audio ARC Series 10 subwoofers handle 500 watts RMS combined. 250 watts RMS per driver. For best results in the Performance Optimized Dual Sealed 10 enclosure, pair the ARC 10 pair with a clean monoblock amplifier delivering 400 to 500 watts RMS at your chosen impedance. Arc Audio XD Series and Mini Series monoblocks in the 500 to 600 watt range are engineered specifically to pair with Arc Audio subwoofers.

What impedance options are available for the Arc Audio ARC Series 10?

The Arc Audio ARC Series 10 is available in two dual voice coil impedance configurations: Dual 2-ohm (D2) and Dual 4-ohm (D4). Two Dual 2-ohm ARC 10s can wire down to 0.5 ohms parallel or 2 ohms series combined. Two Dual 4-ohm ARC 10s can wire down to 1 ohm parallel or 4 ohms series combined. Dual 4-ohm is the more flexible option for most monoblock amplifier setups.

Why choose dual Arc ARC 10s over a single Arc ARC 12?

Two Arc Audio ARC Series 10 subwoofers deliver approximately 157 square inches of combined cone area vs 113 square inches for a single Arc ARC 12. The dual 10 configuration produces faster transient response due to lower per-driver cone mass, cleaner midbass integration, and lower distortion at any given SPL because each driver operates at lower excursion. A single ARC 12 offers a smaller cabinet footprint and higher output per driver, but the dual 10 pair is the better SQ choice.

What mounting hardware does the Performance Optimized Dual Sealed 10 for Arc Audio ARC 10 include?

The Performance Optimized Dual Sealed 10 for Arc Audio ARC 10 includes 8/32 threaded inserts pressed into both baffle backsides and stainless steel mounting screws sized for the Arc Audio ARC 10. The enclosure also includes a Proline X ABS/carbon fiber composite terminal cup pre-wired with 12-gauge OFC and stainless steel input hardware.

What carpet and acrylic insert options are available on the Performance Optimized Dual Sealed 10 for Arc Audio ARC 10?

Carpet and insert selections are cosmetic only and do not affect acoustic performance.

Where is the Performance Optimized Dual Sealed 10 for Arc Audio ARC 10 manufactured?

The Performance Optimized Dual Sealed 10 for Arc Audio ARC 10 is manufactured in Tullahoma, Tennessee, USA. Each enclosure is CNC-cut from Langboard Elite 3/4" MDF on ShopSabre routers and hand-assembled at Audio Intensity's Tennessee facility. Build time is 2 to 5 business days from order placement.
