Performance Optimized Wedge Sealed Dual 10" Enclosure | Ampere Audio AA-2.0 10

Q: Does this fit the Ampere Audio AA-2.0 10, and will any other 10 inch fit?

The AA-2.0 10, yes, in both coil versions. The baffle is cut to 9.13 in, Ampere's published cutout, under the 10.28 in frame. The 5.61 inch motor clears the cabinet with 3.72 inch to spare. Run two of the same coil so the chambers match.Any other 10, no. The airspace is engineered around the AA-2.0 10's own Qts and Vas, and a different woofer that happened to drop into the hole would not see the alignment printed on this page.

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

Ampere rates the AA-2.0 10 at 500 watts RMS per driver, so target 350 to 500 watts RMS per driver at the final load.Ampere sells the AA-2.0 10 as dual 2 ohm and dual 4 ohm; a matched pair should share a coil. A pair of dual 2 ohm drivers lands on 2 ohms with each woofer's coils in series and the two woofers in parallel, or 8 ohms all in series. A pair of dual 4 ohm drivers lands on 4 ohms with each woofer's coils in series and the woofers in parallel, or 1 ohm with everything in parallel. Anything under 1 ohm, and many amplifiers at 1 ohm, is outside what the amplifier is built for, so series wiring is the safe default. Confirm your amplifier's minimum stable impedance first.

Q: Why the wedge angle, and why rear-firing into the trunk?

The seat-side face carries a 20 degree rake that matches the lean of a factory rear seat back, so the cabinet sits flush against it and the cargo space in front stays usable. The baffle is the vertical trunk-lid-side face, so the drivers fire rearward into the trunk cavity.The trunk acts as an acoustic extension for the sealed box, and the cabin adds real output below 50 Hz, so in-vehicle response runs deeper than the anechoic 50.2 Hz on the dual 2 ohm and 44.9 Hz on the dual 4 ohm on this page.

Q: Why two separate chambers instead of one shared volume?

Two drivers sharing one sealed volume load each other: each driver's compression stroke becomes the pressure the other works against, which blurs the alignment either would have alone. A bonded full-height 3/4 inch divider gives each driver its own 1.03 cubic feet and its own polyfill.It also means a failure in one driver does not unload the other, and the alignment on this page is the alignment in each chamber, not an average across a shared box.

Q: What is the expected low-frequency extension?

Anechoic F3 is 50.2 Hz on the dual 2 ohm and 44.9 Hz on the dual 4 ohm per chamber. The lower-Q coil rolls off gently with F3 above fc; the higher-Q coil carries a small lift near resonance.Those figures exclude cabin gain. In a car the cabin's transfer function adds real output below 50 Hz, so in-vehicle response runs deeper than the numbers above.

Q: Do I need to add polyfill or damping?

No. Polyfill is already installed in both chambers as a light wall lining to control internal reflections, and the quantity is chosen so it does not change the acoustic volume.Do not add more. Packing a sealed box with fill makes it behave as though it were larger, which walks the alignment away from the 1.03 cubic feet per chamber this cabinet was built to.

Q: Is the driver included, and are the threaded inserts installed?

No driver. This is an enclosure only. You receive the cabinet finished in plush black carpet with the gloss black acrylic baffle insert, one side-mounted pre-wired terminal cup to both positions, the polyfill lining already in place, and a threaded insert kit with stainless machine screws.The inserts ship loose on purpose: Ampere prints no bolt circle for the AA-2.0 10, so you set the driver in the recess, mark its holes, drill and press the inserts. The pair of Ampere Audio AA-2.0 10 is purchased separately, and the cabinet is cut direct fit to it, not a general purpose 10 inch box.

A Pair of Ampere Audio AA-2.0 10 in a Sealed Wedge

The AA-2.0 10 is Ampere's 10 inch in the AA-2.0 series: a steel basket, paper and foam cone, a 2 inch four-layer copper voice coil and a dual 40 ounce magnet, rated 500 watts RMS with 14 mm of one-way excursion, 5.61 inches of mounting depth on a 10.28 inch frame. Every Thiele-Small figure comes from Ampere's own published table for the AA-2.0 10, and the table holds together: the moving mass and resonance reproduce the published Vas on a cone area in class for a 10 inch driver. Ampere prints no cone area for this driver, so the 326 square centimeters used for excursion and output figures is derived from Ampere's own Vas, resonance and moving mass.

1.03 cubic feet net per chamber on Ampere's published figures: the dual 2 ohm reads Qtc 0.655 with resonance at 46.3 Hz and half power at 50.2 Hz, and the dual 4 ohm reads Qtc 0.757 with resonance at 47.9 Hz and half power at 44.9 Hz. One cabinet serves both coils, built to the volume that keeps both closest to maximally flat. That is spread either side of maximally flat: the lower-Q coil a little drier, the higher-Q coil a little punchier.

Two Fully Separate Chambers

A bonded full-height 3/4 inch MDF divider splits the cabinet into two sealed chambers of 1.03 cubic feet net each, so every driver sees exactly the airspace printed on this page. Two drivers sharing one volume load each other; the divider removes that, and each chamber carries its own polyfill.

The cabinet is pinned at the 32 inch dual width cap, 15 inches tall, 10.02 inches deep at the top and 15.48 at the base, with the depth absorbing the airspace. One shared side-mounted terminal cup feeds both driver positions.

Trunk-Load Wedge Design Explained

The drivers mount on the vertical trunk-lid-side face and fire rearward into the trunk cavity.

Seat-Side Face Matches Seat Lean

Angled face matches the roughly 20 degree factory seat lean.

Trunk-Lid-Side Face Fires the Woofers

Vertical baffle, cones firing rearward into the trunk cavity.

Trunk Cavity Loading

The trunk acts as an acoustic extension for a smoother presentation.

Preserves Trunk Cargo Space

The wedge tucks against the seat back and the space in front stays usable.

Engineered for a pair of Ampere Audio AA-2.0 10

Anechoic half power lands at 50.2 Hz on the dual 2 ohm and 44.9 Hz on the dual 4 ohm, before any cabin gain. Ampere does not publish driver displacement, so an estimated 0.065 cubic feet per driver is taken out of the net figure.

Alignment Numbers (Per Chamber)

Driver (per chamber)	System Qtc	fc	F3
AA-2.0 10 dual 2 ohm	Qtc 0.655	46.3 Hz	50.2 Hz
AA-2.0 10 dual 4 ohm	Qtc 0.757	47.9 Hz	44.9 Hz

Mounting Geometry

The baffle is cut to 9.13 in, Ampere's published cutout, under the 10.28 in frame. The rear panel rakes 20 degrees, so the cavity deepens from 10.02 in at the top to 15.48 in at the base, and the 5.61 in motor clears it with 3.72 in to spare. Ampere prints no bolt circle for the AA-2.0 10, so the baffle ships undrilled with a threaded insert kit and stainless machine screws: set the driver in the recess, mark its holes, drill, press the inserts and bolt it down.

Wiring a pair of Ampere Audio AA-2.0 10 to Your Amplifier

Ampere sells the AA-2.0 10 as dual 2 ohm and dual 4 ohm; a matched pair should share a coil. A pair of dual 2 ohm drivers lands on 2 ohms with each woofer's coils in series and the two woofers in parallel, or 8 ohms all in series. A pair of dual 4 ohm drivers lands on 4 ohms with each woofer's coils in series and the woofers in parallel, or 1 ohm with everything in parallel. Anything under 1 ohm, and many amplifiers at 1 ohm, is outside what the amplifier is built for, so series wiring is the safe default. Confirm the final load against your amplifier's minimum stable impedance before powering the system.

Power handling is 500 watts RMS per driver, 1000 across the pair. Aim for roughly 350 to 500 watts per driver at the impedance you wire.

This enclosure holds 1.03 cu ft net per chamber. In it the Ampere Audio AA-2.0 10 runs a system Qtc of 0.66–0.76 with half power at 44.9–50.2 Hz, and the cone reaches its 14.0 mm travel limit at 311 W, below the driver’s 500 W thermal rating, so travel is what stops you here, not heat. Run a subsonic filter at 25 Hz and that becomes 385 W — +74 W, or 24 percent more power for the same 14.0 mm of travel.

01Is it a sealed driver?

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

EBP = Fs ÷ Qes = 52.8–61.0

D2 · EBP 61.0D4 · EBP 52.8

At 52.8–61.0 the AA-2.0 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

1.03 cu ft against a 19.0 L Vas.

α = Vas ÷ Vb = 0.65 · Fc = Fs√(α+1) = 46–48 Hz · Qtc = 0.66–0.76

D2 · Qtc 0.66, Fc 46 Hz, F3 50.2 HzD4 · Qtc 0.76, Fc 48 Hz, F3 44.9 Hz

The box lifts resonance from 35.4–36.0 Hz free-air to 46–48 Hz and half power lands at 44.9–50.2 Hz, anechoic, before any cabin gain. Ampere prints no cone area for this driver; it is derived from Ampere’s own Vas, Fs and moving mass. Driver displacement is not published and is estimated.

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

P_Xmax = 311–313 W unfiltered → 385–451 W with a 25 Hz subsonic

D2 · 313 W, no filterD4 · 311 W, no filterD2 · 451 W with subsonic at 25 Hz, 24 dB/octD4 · 385 W with subsonic at 25 Hz, 24 dB/octXmax 14.0 mm one-way

Every trace touches the limit and no further, because each is drawn at the exact power that puts that coil on 14.0 mm. Unfiltered that is 311 W, reached first at 20 Hz. It sits under the 500 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 385 W before hitting the same 14.0 mm. That is 24 percent more amplifier for the price of one filter setting.

Materials

Material

Built From a Spec Sheet, Not a Sales Sheet

Every Proline X Performance 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 Performance 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.
