01Is this driver right for a ported box?

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

EBP = Fs ÷ Qes = 87.6
SEALED 0–50 TRANSITION 50–100 PORTED 100–150 0 50 100 150 EBP 87.6
American Bass Hurricane 15 D1 · EBP 87.6
Between 50 and 100 a driver takes either load, and the choice becomes one of priorities rather than of physics. The American Bass Hurricane 15 D1 reads 87.6. Ported buys output and low-end reach around tuning; sealed buys a shallower rolloff below it. This cabinet takes the first trade.

02What the box does to it

4.37 cu ft net against a 52.7 L Vas, vented at 37.0 Hz.

Fb = 37.0 Hz  ·  F3 = 31.0 Hz  ·  passband ripple 5.51 dB
20 30 50 70 100 150 200 +8 +4 0 −4 −8 −12 −16 −20 −24 −28 −32 −36 FREQUENCY · Hz LEVEL · dB −3 dB Fb 37.0
American Bass Hurricane 15 D1 · Fb 37.0 Hz, F3 31.0 Hz
Anechoic, before any cabin gain, with the 29 Hz subsonic filter already applied. The vent takes over below 37 Hz and the cone stops doing the work there, which is what holds travel down at the bottom of the passband.

03Ported vs Sealed

No sealed comparison is shown for this driver.

A ported-versus-sealed chart is only worth reading against a sealed box someone would actually build: the one we make for the driver, or the one its maker recommends. Neither exists for the American Bass Hurricane 15 D1 — we do not build a sealed enclosure for it and American Bass publish no sealed volume for it — so rather than compare this cabinet against itself stuffed and sealed, a box no one would build, the comparison is left out.

04The 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 American Bass's published 25.0 mm. The two traces are the same cabinet with the subsonic filter switched on and switched off.

PXmax = 14169 W with a 29 Hz subsonic  ·  3067 W with none  →  the filter is worth 4.6×
20 30 50 70 100 150 200 0 8 16 24 FREQUENCY · Hz CONE TRAVEL · mm PAST LINEAR TRAVEL · Xmax 25.0 mm 14169 W reaches Xmax here
14169 W · subsonic at 29 Hz, 24 dB/oct3067 W · no subsonic filterXmax 25.0 mm one-way, published
Each trace touches the limit and no further, because each is drawn at the exact power that puts the cone on 25.0 mm. With a 29 Hz subsonic that takes 14169 W, reached first at 30 Hz. Take the filter away and the same cabinet reaches 25.0 mm on 3067 W — the filter is worth 4.6× the safe power. A vent unloads the cone below tuning, so there is nothing holding it once the box stops loading: on a sealed build a subsonic filter is an improvement, here it is required equipment. The unfiltered trace is still rising where this chart stops at 20 Hz, so treat 3067 W as a bound rather than a floor. Every wattage on this page is a MECHANICAL limit, not an electrical one. It is the power at which the cone runs out of linear travel in this cabinet, and nothing more. What the voice coil can dissipate as heat is a separate ceiling set by the driver, not by the box — American Bass rate this one at 3000 W RMS, and that is the number that binds first here: heat stops you before travel does, so treat 3000 W as the ceiling and the travel figures above as headroom. Final wired impedance, amplifier output and how long you hold the level are all electrical questions this graph does not answer.

From the shop floor

Installer's take

I built this box for one Hurricane 15 on the full Professional chassis: three layers of baffle with the frame flush in the outer one, and a slot port that runs along the back wall to put 37.0 Hz in a 25.2 inch deep box.

One cabinet serves both coils. It was solved so the Hurricane 15 D1 and the D2 each pass every velocity, excursion and ripple gate in the same box.

American Bass publishes no bolt circle, so the box ships with a threaded insert kit rather than pressed inserts.

3000 watts RMS by American Bass's rating. The D1 wires to 2 ohms with its coils in series or 0.5 ohm in parallel; the D2 wires to 4 ohms with its coils in series or 1 ohm in parallel. American Bass publishes no mounting hole locations for the Hurricane 15, so the inserts are not in the baffle when the box arrives. The insert kit is in the box: set the inserts where the woofer's own holes fall, with the drill bit and the 2.5 inch allen-head screws in the kit, and lay the gasket tape before the woofer goes down.

It ships dry. Do not add polyfill to a ported box. Set your subsonic filter at 29 Hz.

Questions

Why is this enclosure tuned to 37.0 Hz?

Sealed, the Hurricane 15 needs 0.43 cubic feet net to reach a Qtc of 0.707. Vented, it trades that for deeper extension. The slot is gated at 3600 W, 1.2 times American Bass's rating: the channel runs 20.8 m/s and the mouth 17.0, and the cone peaks at 12.6 of its 25 mm with the subsonic filter in place. Tuning is chosen for in-car response rather than an anechoic curve: a vehicle adds roughly 12 dB per octave below about 45 Hz, and this tuning is where that sum comes out flattest across 25 to 60 Hz.

Why is this a Professional build and not a Performance Optimized box?

Every driver is run through the Performance Optimized wedge and down-fire before this chassis; the Professional box is where a driver lands when that smaller envelope, 30 inches wide and 18 inches deep with a triangular side port, cannot give it what it needs at its rated power. The Hurricane 15 does not fit that envelope at all: no tuning, width or depth inside it carries an 11.89 inch deep 15 inch driver at 3000 W. This box is the chassis with the width, depth and port to carry it. An under-ported box does not fail quietly. Air speed at the mouth rises with power; past the chuff line the flow turns turbulent and the port is audible on every note. The turbulence also chokes the port, so the box behaves as if it were tuned higher than it is, loses output near tuning, and lets the cone travel further below tuning than the design allows. This chassis is a full-size front-firing box on a 2.25 inch baffle built from three 3/4 inch layers with the woofer flush-mounted in the outer layer, an American Bass logo acrylic, and a port and excursion budget checked at 3600 W. It carries a 2 year warranty, against 1 year on the Performance Optimized lines.

Threaded inserts or a kit?

American Bass does not publish the mounting hole locations for the Hurricane 15, so we cannot install the threaded inserts before it ships. The threaded insert kit comes in the box instead: inserts sized to the woofer, the correct drill bit, 2.5 inch allen-head screws, an allen key and woofer gasket tape. You set the inserts when you mount the woofer, and this box ships with one kit.

Do I need a subsonic filter?

Yes, at 29 Hz, 24 dB per octave. Below tuning a vented box stops loading the cone and excursion runs away toward DC. With the filter in place this cabinet puts the American Bass Hurricane 15 at 50 percent of its usable travel at 3600 W.

Would a sealed box be better for me?

Not one we can show you. We do not build a sealed enclosure for the American Bass Hurricane 15 and American Bass publish no sealed volume for it, so the Performance Graphs tab carries no ported-versus-sealed chart: the only sealed box left to plot would be this cabinet stuffed and sealed, which nobody would build, and a comparison against it would tell you nothing you could buy. What a vented box gives up is the region below tuning, where the cone unloads and the 29 Hz subsonic filter takes over; around 37.0 Hz the vent carries the load and cone travel drops to its minimum, which no sealed alignment can do.

How does the front port work?

It is a vertical slot beside the woofer, the full height of the cavity, 6.50 inches wide and 107.2 square inches. It runs 15.00 inches to the back wall and turns once along it for 9.12 inches; the fold costs about 1.5 Hz and the port is cut for it. The channel runs at 20.8 metres per second at 3600 W, 23 percent of its turbulence limit, and the mouth edges carry a 1/2 inch roundover so the air leaves the face at 17.0 metres per second against the 17 metres per second threshold where a slot starts to chuff.

What does the price cover, and how does it ship?

83 lb, 35.00" W x 18.00" H x 25.25" D external. Every Professional cabinet is priced the same way, by its size: this one is 9.21 cubic feet outside. Delivery to the 48 states is inside the price; it ships as a 83 lb parcel and checkout adds nothing. Do not add polyfill; it ships dry on purpose.

Is the Hurricane 15 included?

No. This is an enclosure only, cut for the American Bass Hurricane 15 specifically: the 13.780 inch cutout, the 11.890 inch mounting depth allowance and the 4.37 cubic foot alignment all come from American Bass's published parameters. It fits both coil versions (D1 and D2), and the cabinet was checked against both. Bring your own driver.
