This enclosure holds 0.820 cu ft net per driver. In it the American Bass Hawk Slim 10 D2 runs a system Qtc of 0.63–0.79 with half power at 49.6–56.9 Hz, and the cone reaches its 10.5 mm travel limit at 241 W per driver, below the driver’s 700 W thermal rating, so travel is what stops you here, not heat. Run a subsonic filter at 25 Hz and that becomes 314 W per driver — +73 W, or 31 percent more power for the same 10.5 mm of travel.

00Sizing the amplifier

Every wattage on this panel is per driver. This cabinet holds four, so the amplifier feeds all four at once.

Per driver 220–310 W RMS  ×  4 drivers  =  full set 880–1,240 W RMS
Look for a mono amplifier rated 880–1,240 W RMS at the load your coil version wires to. Travel sets the top here, not heat: past 314 W per driver the cone runs beyond Xmax even with the subsonic set, under the driver’s 700 W thermal rating. The top of the range needs the 25 Hz subsonic filter set; without it, keep each driver under 241 W, where the cone reaches Xmax unfiltered. Below the bottom of the range it will play, just with less headroom; above the top you are buying power the drivers cannot use.

01Is it a sealed driver?

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

EBP = Fs ÷ Qes = 59.5–68.0
SEALED 0–50 TRANSITION 50–100 PORTED 100–150 0 50 100 150 Dual 2 Ohm 68.0 Dual 4 Ohm 59.5
Dual 2 Ohm · EBP 68.0Dual 4 Ohm · EBP 59.5
At 59.5–68.0 the Hawk Slim 10 D2 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

0.820 cu ft against a 16.4 L Vas.

α = Vas ÷ Vb = 0.71  ·  Fc = Fs√(α+1) = 50–55 Hz  ·  Qtc = 0.63–0.79
20 30 50 70 100 150 200 +6 +0 -6 -12 -18 -24 FREQUENCY · Hz LEVEL · dB −3 dB
Dual 2 Ohm · Qtc 0.63, Fc 50 Hz, F3 56.9 HzDual 4 Ohm · Qtc 0.79, Fc 55 Hz, F3 49.6 Hz
The box lifts resonance from 38.1–41.5 Hz free-air to 50–55 Hz and half power lands at 49.6–56.9 Hz, anechoic, before any cabin gain. Figures are American Bass’s published parameters; Qes and Qms reproduce the printed Qts. This cabinet holds four drivers in two sealed chambers of 1.639 cubic feet, two drivers to a chamber, so each driver works into 0.820 cubic feet and that is the volume plotted here.

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 10.5 mm — and a bigger one once a subsonic filter stops it wasting travel below the passband.

PXmax = 241–281 W per driver unfiltered  →  314–343 W with a 25 Hz subsonic
20 30 50 70 100 150 200 0 4 8 12 FREQUENCY · Hz CONE TRAVEL · mm PAST LINEAR TRAVEL · Xmax 10.5 mm 241 W reaches Xmax here
Dual 2 Ohm · 241 W, no filterDual 4 Ohm · 281 W, no filterDual 2 Ohm · 343 W with subsonic at 25 Hz, 24 dB/octDual 4 Ohm · 314 W with subsonic at 25 Hz, 24 dB/octXmax 10.5 mm one-way
Every trace touches the limit and no further, because each is drawn at the exact power that puts that coil on 10.5 mm. Unfiltered that is 241 W per driver, reached first at 20 Hz. It sits under the 700 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 314 W per driver before hitting the same 10.5 mm. That is 31 percent more amplifier for the price of one filter setting.

From the shop floor

Installer's take

Start with the size. 0.820 cubic feet per driver puts the Hawk Slim 10 at Qtc 0.627, resonance 49.7 Hz, half power 56.9 Hz anechoic. One box serves Dual 2 Ohm and Dual 4 Ohm, so the depth is the one that keeps both closest to 0.707. One box serves every coil version: the Dual 2 Ohm at Qtc 0.627, the Dual 4 Ohm at Qtc 0.787.

Measure the base depth, not the top. This cabinet is 15.50 in deep where it meets the floor, 9.31 at the top, 44 wide and 17 tall. In an SUV the 44 has to clear between the rear wheel wells at floor height, the base depth is measured from the seat back with the seat upright and latched, and the 17 has to clear the cargo cover.

The two terminal cups are on the side panels, one per chamber, so they sit close to the wheel wells. Land the speaker wire on both before the box slides into its final spot, with slack to pull it forward again.

Two drivers share each chamber, so they have to match: same model, same coil, wired in phase. One driver reversed in a shared chamber pushes against its partner and the pair cancels instead of adding. Check polarity at each cup with a battery tap before the box goes in. The outer pair sits 3.44 in lower than the inner pair on purpose: that is how four 10.857 in frames fit across 44 in. The frames mount on the face rather than in a recess.

Impedance. Hawk Slim 10 D2: wire for 4 ohms (coils in series, each chamber's pair in series, both cups in parallel), the load most monoblocks are built to deliver full power into; 1 ohm is the other clean option (coils in series, each chamber's pair in parallel, both cups in parallel). Hawk Slim 10 D4: wire for 2 ohms (coils in series, each chamber's pair in parallel, both cups in parallel), the load most monoblocks are built to deliver full power into; 8 ohms is the other clean option (coils in series, each chamber's pair in series, both cups in parallel). Work the load out before you buy the amplifier, not after.

Power. Size the amplifier for the set, not one driver: 220 to 310 W RMS per driver is 880 to 1,240 W RMS across all 4. On this driver travel sets the top, not heat: Xmax arrives at 314 W per driver with a 25 Hz subsonic, under the 700 W rating. Set the 25 Hz subsonic to use the top of that range; without it keep each driver under 241 W.

American Bass's Qes and Qms reproduce the printed Qts within 3 percent, so the alignment rests on a self-consistent set. American Bass do not publish driver displacement; we deduct an estimated 0.040 per driver, so true net can sit a few hundredths either way.

Polyfill is in as a wall lining in every chamber. Do not add more: it makes the box act larger and walks Qtc off 0.63.

Before you order

Questions

Does this fit the American Bass Hawk Slim 10, and its coil versions?

Yes. Each opening is cut to 9.410 in for the 10.857 in frame, and the 3.15 in deep motor clears the raked rear panel with 5.17 in to spare. Both coil versions share the frame, cutout and mounting depth; the alignment table lists each.

Run four matched drivers, same model and same coil, so every chamber sees the alignment on this page.

Why 0.820 cubic feet per driver, and what alignment does it target?

On American Bass's published Fs 38.1 Hz, Qts 0.480 and Vas 16.4 liters, 0.820 cubic feet per driver gives Qtc 0.627, system resonance 49.7 Hz and half power 56.9 Hz.

One box serves Dual 2 Ohm and Dual 4 Ohm, so the depth is the one that keeps both closest to 0.707.

What amplifier power should I run, and how should I wire it?

American Bass rates the Hawk Slim 10 at 700 watts RMS per driver. Recommended amplifier: 220 to 310 W RMS per driver, 880 to 1,240 W RMS for the full set of 4. Travel, not heat, sets the top: the cone reaches Xmax at 314 W per driver with a 25 Hz subsonic set, under the 700 W rating. The top of that range needs the 25 Hz subsonic; without it keep each driver under 241 W.

Each Hawk Slim 10 D2 has two 2 ohm voice coils, 4 ohms in series or 1 ohm in parallel. Wire every driver's coils in series. With the two drivers in each chamber in parallel and the two cups in parallel, the four present 1 ohm to a mono amplifier. With the two drivers in each chamber in series and the two cups in parallel, they present 4 ohms. Use the lower load only on an amplifier rated stable there. Each Hawk Slim 10 D4 has two 4 ohm voice coils, 8 ohms in series or 2 ohms in parallel. Wire every driver's coils in series. With the two drivers in each chamber in parallel and the two cups in parallel, the four present 2 ohms to a mono amplifier. With the two drivers in each chamber in series and the two cups in parallel, they present 8 ohms. Use the lower load only on an amplifier rated stable there.

Will it fit my SUV?

It is 44 inches wide, 17 tall and 15.50 deep at the base, tapering to 9.31 at the top. Measure between the rear wheel wells, the floor depth with the seat upright, and the height under your cargo cover.

The raked face goes against the seat back and the woofers fire toward the liftgate.

Why two drivers per chamber instead of four chambers?

Four chambers would need three dividers, and on a 44 inch face that space is needed for the woofers. Two matched drivers in one sealed chamber move together and see the same pressure, so each behaves as if it had half the chamber to itself: 0.820 cubic feet per driver here.

It also gives two terminal cups, one per pair, which keeps the wiring to the amplifier simple.

What is the expected low-frequency extension?

Anechoic F3 is 56.9 Hz per driver with system resonance at 49.7 Hz.

Those figures exclude cabin gain. An SUV cabin adds real output below about 50 Hz, so in-vehicle response runs deeper than the numbers above.

Do I need to add polyfill or damping?

No. Polyfill is already installed as a light wall lining in every chamber, and the quantity is chosen so it does not change the acoustic volume.

Do not add more. Packing a sealed box makes it behave as though it were larger, which moves the alignment away from 0.820 cubic feet per driver.

Are the drivers included?

No. This is an enclosure only. You receive the cabinet finished in plush black carpet with the gloss black acrylic baffle insert, two side-mounted pre-wired terminal cups, the polyfill lining in place, threaded inserts and stainless machine screws.

Bring four matched American Bass Hawk Slim 10 drivers. The cabinet is cut direct fit to them, not a general purpose 10 inch box.
