Performance Optimized Wedge Sealed 10" Enclosure | Audiomobile GT2 2010

Q: Does this fit the Audiomobile GT2 2010, and will any other 10 inch fit?

The GT2 2010, yes. The baffle is cut to 9.2 in, Audiomobile's published mounting hole, and the 4.25 in motor clears the raked back with 0.75 in to spare.Any other 10, no. The airspace is set for the GT2'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?

Audiomobile rates the GT2 2010 at 400 watts RMS, so target 280 to 400 watts RMS at the final load.The GT2 2010 has a single 3 ohm coil (2.8 ohms DC), so one driver presents 3 ohms to a mono amplifier. 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 driver fires 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 34.6 Hz on this page.

Q: Why is the front baffle double-layered?

The baffle is two bonded 3/4 inch sheets, 1.5 inches through. A single 3/4 inch panel flexes under the pressure a 10 inch woofer puts on it at 400 watts, which smears output and works the driver loose over time; the second layer stiffens the face and gives the mounting hardware twice the material to bite.The outer layer is machined as a flush recess to the 10.65 inch frame, so the driver bolts to the inner layer and sits flush with the gloss black acrylic insert.

Q: What is the expected low-frequency extension?

Anechoic F3 is 34.6 Hz with system resonance at 43.2 Hz. Above Qtc 0.707 F3 sits below fc, so the response carries a lift near resonance before it rolls off.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 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 0.80 cubic feet 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, the polyfill lining already in place, and a threaded insert kit with stainless machine screws.The inserts ship loose on purpose: Audiomobile prints no bolt circle for the GT2 2010, so you set the driver in its recess, mark its holes, drill and press the inserts. The GT2 2010 is purchased separately.

INSTALLER'S TAKE

0.80 cubic feet, Qtc 0.958, F3 34.6 Hz. The GT2 is a 0.61 Qts driver, so sealed it is punchy rather than flat; flat would take 3.4 cubic feet.

The 4.25 inch motor sets the top of the wedge at 6.09 with the 0.75 minimum over it; 10.82 at the base, 27.22 wide, 13 tall.

Audiomobile recommends the GT2 vented. This is the sealed choice for a buyer who wants it tight and small; the vented box goes deeper.

No published bolt circle, so the inserts ship in the kit: mark from the driver, drill, press. Sealed, so leave the polyfill as it is, 280 to 400 watts.

The Audiomobile GT2 2010 in a Sealed Wedge

The GT2 2010 is Audiomobile's shallow 10 on a low-profile steel frame with radial thermal venting: 4.25 inches of mounting depth, 11.9 mm of one-way excursion at 70 percent of Bl, 400 watts RMS and a 3 ohm coil (2.8 ohms DC). Audiomobile's own figures hold together: Qes 0.64 and Qms 7.1 reproduce the printed Qts within 4 percent, and the 346 square centimeter cone and 33.2 liter Vas put the moving mass within 8 percent of the published 187 g.

0.80 cubic feet net on Fs 27.5 Hz, Qts 0.61 and Vas 33.2 liters: Qtc 0.958, system resonance 43.2 Hz, half power 34.6 Hz. That is above maximally flat, a firm, punchy sealed box with a lift near resonance. A Qts of 0.61 is high enough that the flat box would need 3.4 cubic feet, far past what a trunk wedge should be, and Audiomobile itself recommends the GT2 vented, 0.75 to 1.25 cubic feet at 33 to 37 Hz; this is the sealed alternative.

Trunk-Load Wedge Design Explained

The driver mounts on the vertical trunk-lid-side face and fires 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 Woofer

Vertical baffle, cone 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 the Audiomobile GT2 2010

Anechoic half power lands at 34.6 Hz, before any cabin gain. Audiomobile publishes no displacement for the GT2 2010, so an estimated 0.088 cubic feet is taken out of the net figure.

Mounting Geometry

The baffle is CNC cut to 9.2 in, Audiomobile's published mounting hole, under a 10.65 in frame. The rear panel rakes 20 degrees, so the cavity deepens from 6.09 in at the top to 10.82 in at the base, and the 4.25 in motor clears it with 0.75 in to spare. Audiomobile prints no bolt circle for the GT2 2010, so the baffle ships undrilled with a threaded insert kit and stainless machine screws: set the driver in its recess, mark its holes, drill, press the inserts and bolt it down.

What the Numbers Rest On

Langboard Elite MDF

Premium 3/4 in MDF throughout.

V-Groove and Dado Joinery

CNC cut V-grooves at every panel intersection, sides and brace seated in dados.

Double-Layer 1.5" Front Baffle

Wiring the Audiomobile GT2 2010 to Your Amplifier

The GT2 2010 has a single 3 ohm coil (2.8 ohms DC), so one driver presents 3 ohms to a mono amplifier. Confirm the final load against your amplifier's minimum stable impedance before powering the system.

Power handling is 400 watts RMS per driver. Aim for roughly 280 to 400 watts at the impedance you wire.

This enclosure holds 0.80 cu ft net . In it the Audiomobile GT2 2010 runs a system Qtc of 0.96 with half power at 34.6 Hz, and the cone reaches its 11.9 mm travel limit at 194 W, below the driver’s 400 W thermal rating, so travel is what stops you here, not heat. Run a subsonic filter at 25 Hz and that becomes 218 W — +24 W, or 12 percent more power for the same 11.9 mm of travel.

01Is it a sealed driver?

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

EBP = Fs ÷ Qes = 43.0

3 ohm · EBP 43.0

EBP under 50 means a motor that wants a sealed load. The GT2 2010 sits at 43.0, inside that band, which is why this is a sealed build rather than a ported one.

02What the box does to it

0.80 cu ft against a 33.2 L Vas.

α = Vas ÷ Vb = 1.47 · Fc = Fs√(α+1) = 43 Hz · Qtc = 0.96

3 ohm · Qtc 0.96, Fc 43 Hz, F3 34.6 Hz

The box lifts resonance from 27.5 Hz free-air to 43 Hz and half power lands at 34.6 Hz, anechoic, before any cabin gain. Audiomobile recommends only a vented box for the GT2 2010 and publishes no displacement; 0.088 cubic feet is estimated. With a Qts of 0.61 no trunk-sized sealed box reaches maximally flat; 0.80 cubic feet per driver reads Qtc 0.96.

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

P_Xmax = 194 W unfiltered → 218 W with a 25 Hz subsonic

3 ohm · 194 W, no filter3 ohm · 218 W with subsonic at 25 Hz, 24 dB/octXmax 11.9 mm one-way

Every trace touches the limit and no further, because each is drawn at the exact power that puts that coil on 11.9 mm. Unfiltered that is 194 W, reached first at 29 Hz. It sits under the 400 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 218 W before hitting the same 11.9 mm. That is 12 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.
