Why this driver is vented at 33.0 Hz
The JL Audio 10W7AE pairs a deep motor with a wide Xmax, and this cabinet gives it 1.70 cubic feet net, vented at 33.0 Hz through a 22.0 square inch port. F3 lands at 28.7 Hz with 2.64 dB of passband ripple. It is the single-driver ported box in the professional JL Audio line.
The port on this box stays clean up to 356 W before the mouth velocity crosses the chuff threshold, against the coil's own 750 W power rating; JL Audio's own T/S are published in full, so this alignment rests on numbers the manufacturer stands behind rather than a derived substitute. Ripple across the passband holds at 2.64 dB, and the in-car curve stays tight across the passband rather than peaking at either end. There is no sealed reference for the 10W7AE in our data, so no sealed-versus-ported comparison is offered for this driver.
The cabinet
32.00" W x 12.50" H x 15.00" D external, internally braced. It ships as a UPS parcel; the price includes shipping in the 48 states.
This is our single-ten ported envelope built around the 10W7AE's frame and its deep motor.
The numbers to respect
JL Audio publish full T/S for the 10W7AE, and loudspeakerdatabase.com mirrors the same coil-specific figures used here; nothing about this driver's data needed correction or estimation. There is no conflict between the Q2 catalog sheet and the store listing on this cabinet's dimensions.
This cabinet is 1.70 cubic feet net, with a slot port of 22.0 square inches tuned to 33.0 Hz; the port stays under the chuff threshold up to 356 W; above that the air at the mouth moves faster than the 17 metres per second where a slot starts to chuff.
Set a 26 Hz subsonic filter, 24 dB per octave. Below tuning the vent stops loading the cone; with the filter in place the cone reaches 14.7 mm of its 23.0 mm at 1125 W.

01Is this driver right for a ported box?
Efficiency bandwidth product places the motor before anything else is decided.
EBP = Fs ÷ Qes = 52.8
JL Audio 10W7AE-3 · EBP 52.8
Between 50 and 100 a driver takes either load, and the choice becomes one of priorities rather than of physics. The JL Audio 10W7AE-3 reads 52.8. 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
1.70 cu ft net against a 36.1 L Vas, vented at 33.0 Hz.
Fb = 33.0 Hz · F3 = 28.7 Hz · passband ripple 2.64 dB
JL Audio 10W7AE-3 · Fb 33.0 Hz, F3 28.7 Hz
Anechoic, before any cabin gain, with the 26 Hz subsonic filter already applied. The vent takes over below 33 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 JL Audio 10W7AE-3 — we do not build a sealed enclosure for it and JL Audio 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 JL Audio's published 23.0 mm. The two traces are the same cabinet with the subsonic filter switched on and switched off.
PXmax = 2747 W with a 26 Hz subsonic · 551 W with none → the filter is worth 5.0×
2747 W · subsonic at 26 Hz, 24 dB/oct551 W · no subsonic filterXmax 23.0 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 23.0 mm. With a 26 Hz subsonic that takes 2747 W, reached first at 24 Hz. Take the filter away and the same cabinet reaches 23.0 mm on 551 W — the filter is worth 5.0× 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 551 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 — JL Audio rate this one at 750 W RMS, and that is the number that binds first here: heat stops you before travel does, so treat 750 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.
The JL Audio 10W7AE-3 is the driver this enclosure was built around, a 10" subwoofer that delivers reference-grade sub-bass in a format that fits where a 12" or 15" cannot. With 23mm of one-way linear Xmax, 750 watts RMS power handling, and a single 3Ω voice coil, the 10W7AE-3 produces the kind of accurate, controlled low-frequency output that earned the W7 series its reputation as a benchmark driver. Its Qts of 0.537 and Fs of 30.6Hz place it at the edge of sealed and ported territory, but ported is the correct alignment when the goal is maximum low-frequency extension and output from the 10" format. In a correctly tuned enclosure at 33Hz, the 10W7AE-3 produces deep, accurate bass that tracks complex program material with the composure that defines the W7AE platform.

Material
Built From a Spec Sheet, Not a Sales Sheet
Every Proline X Professional Series enclosure is CNC-cut from Langboard Elite MDF, 3/4" (18mm) panels produced to published mill specifications. Most enclosure manufacturers source generic MDF without published data. We can tell you the internal bond rating, the modulus of elasticity, the modulus of rupture, and the face and edge screw holding strength for every panel in this enclosure, because we chose the material based on those numbers, not on price or availability.
Langboard Elite is produced in the United States. The specifications below are pulled directly from Langboard's published mill data and are verifiable. This is the same panel stock used in our full Proline X lineup.
Specifications
Langboard Elite MDF: Published Mill Data
| Property | Value | Why It Matters |
|---|---|---|
| Panel Stock | Langboard Elite MDF | Named, verifiable panel source, not generic "high-density MDF" |
| Thickness | 3/4" (18mm) | Industry standard for subwoofer enclosures; panels below this flex under pressure |
| Density | 48.5 lbs/ft³ | Higher density = less porosity, better screw retention, reduced resonance |
| Internal Bond | 200 psi | Measures resistance to delamination under sustained internal pressure. The most enclosure-relevant spec on this sheet |
| Modulus of Rupture (MOR) | 4,200 psi | Bending strength before the panel breaks, relevant for larger unsupported baffle spans |
| Modulus of Elasticity (MOE) | 410,000 psi | Stiffness under load; higher MOE means less panel flex under bass pressure, less resonance |
| Face Screw Holding | 325 lbs | How firmly the panel surface holds a screw; critical for baffle joint integrity over time |
| Edge Screw Holding | 250 lbs | Panel edge retention, relevant for every joint that isn't face-to-face |
Internal Bond
200 psi: The Number That Actually Matters for Enclosures
The internal bond rating measures how well the MDF panel resists delamination under sustained pressure applied perpendicular to the face. In a subwoofer enclosure, every bass transient generates a pressure pulse that pushes outward on every panel simultaneously. A panel that begins to delaminate internally loses stiffness gradually. The symptoms are slow: a box that starts to sound softer, less defined, less punchy over months of use. 200 psi internal bond is the spec that determines how long this enclosure holds its acoustic integrity under daily use at real power levels.
Stiffness
410,000 psi MOE: Less Flex, Less Resonance
The modulus of elasticity measures panel stiffness, its resistance to bending under load. A stiffer panel flexes less under the pressure generated by a high-excursion driver at volume. Panel flex is a source of acoustic coloration: the panel itself begins to radiate sound at its own resonant frequency, adding distortion to the output. 410,000 psi stiffness combined with V-groove and dado joinery means the panels stay rigid and the bracing controls resonance at the structure level, not the panel level. The bass you hear comes from the driver, not the box.
Screw Holding
325 lb Face / 250 lb Edge: Joints That Stay Locked
Screw holding strength determines how firmly the panel grips a fastener at the face and at the edge. This matters most at the baffle joint, where the front panel meets the side panels and where the driver is mounted. A panel with low screw holding strength allows fasteners to loosen over time under vibration, leading to air gaps at the joint and loss of acoustic seal. 325 lb face screw holding strength means the baffle hardware stays put. Combined with dado joinery and adhesive, the front panel on a Proline X Professional Series enclosure is not going anywhere.
Sourcing
Named Panel Stock: Not "Premium MDF"
The phrase "premium MDF" or "high-density MDF" appears on marketing copy for enclosures across every price point, from $40 to $400. It is not a specification. It is a description with no defined standard. Langboard Elite is a named, sourced, mill-documented product with published data. We name it in our copy because naming it holds us accountable to the spec. You can look up Langboard Elite independently, verify the numbers on this page, and confirm you are getting what we say you are getting. That is the point.
Why Proline X?
Most enclosures are built to a price point. Proline X is built to a spec. Every box starts with published-data MDF, gets CNC-cut to exact internal volume, and is assembled by hand in our Tennessee facility. The difference shows up in the measurements, and in how the box holds up two years into daily use.
CNC-Cut to Spec
Panels are machine-cut on ShopSabre CNC routers and joined with V-groove and dado joinery. Consistent geometry, no hand-cut variance, no gaps at the joints.
Handcrafted in USA
Hand-assembled at our facility in Tullahoma, TN. Every enclosure is inspected before it ships.
Tuned to the Build
Internal volume and port geometry are calculated to spec and CNC-cut to exact dimensions. The box performs the same way every time.
