Performance Optimized Wedge Ported Dual 10" Enclosure | Audiomobile EVO 2410
Proline X Performance Optimized Wedge Dual 10" Ported
Two EVO 2410 on Audiomobile's 1.0 cubic foot box, tuned to 34 Hz in a trunk wedge
Why this pair is vented at 34.0 Hz
This cabinet is built to Audiomobile's own ported box for the EVO 2410: 2.03 cubic feet net in one shared chamber, 1.02 per driver, the top of the 0.65 to 1.0 range Audiomobile gives, tuned to 34 Hz through a 30.1 square inch triangular port across the pair. Audiomobile does not publish the motor figures (Qes, Qms or Bl) a ported model needs, so this page does not print a modeled F3, ripple or excursion curve the way our other ported pages do: the volume and tuning are the maker's box, not a result of our solver. The port area is scaled from the GT2 2010 dual's solved port by the EVO's larger cone displacement, so it moves the extra air at the same velocity: an estimated 13 m/s at the mouth with both drivers at 500 watts.
The EVO's Fs 27 Hz, Qts 0.50 and Vas 31 liters are not from a published Audiomobile sheet, and no Qes is published at all, which is why the alignment here is Audiomobile's box rather than our model. Displacement is taken as 0.08 cubic feet per driver, and tuning carries a 1.5 Hz fold loss that is an estimate.
Two drivers, one chamber, one port
A ported dual shares its air: one chamber and one port tuned for the pair, so the two cones load the same volume and the port carries both. That is the opposite of our sealed duals, which split the chambers. Two windowed braces at the third points stiffen the 32 inch panels; their windows keep the cavity one chamber and leave each motor clear.
Trunk-load wedge, explained
The cabinet is 32.00 inches wide and 15 tall, 12.25 inches deep at the top and 17.71 at the base. The back rakes 20 degrees to sit against the rear seat; the baffle stays vertical, so the drivers fire rearward into the trunk.
The port is the product
The port is a triangular slot formed by the floor, the back panel and one bevelled panel seated in dados, running 26.1 inches along the back and exiting through the side with a 0.5 inch roundover on all three edges of the mouth. Its 30.1 square inches carry both drivers.
Run a subsonic filter
Below tuning the port stops loading the cones and excursion climbs fast. Set a subsonic filter near 28 Hz and leave it there.
Cut for this driver, not for a catalogue
Both baffle openings are CNC cut to 9.2 in under 10.65 in recesses, centred 8.625 and 23.375 in from the mouth-side edge, with 3.35 in of baffle between the recesses. The 3.9 in motor clears the port panel with 4.79 in to spare. Audiomobile prints no bolt circle, so the baffle ships undrilled with a threaded insert kit and stainless machine screws: set each driver in its recess, mark its holes, drill and press the inserts. Cut from Langboard Elite 3/4 inch MDF with V-groove and dado joinery and a 1.5 inch double baffle.
Power, wiring and warranty
Audiomobile rates the EVO 2410 at 500 watts RMS per driver, 1000 across the pair; aim for 350 to 500 per driver. A pair of dual 4 ohm EVOs wires to 4 ohms (coils in series, pair in parallel) or 1 ohm; a pair of single 4 ohm EVOs to 2 or 8 ohms. It ships dry: do not add polyfill to a ported box. 1 year limited warranty. Enclosure only, the drivers are purchased separately. Call or text 931-563-5151.

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.
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 |
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.
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.
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.
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.
