Proline X Dual 10" Ported System | Loaded with Audiomobile GT2 2010
Proline X Dual 10" Loaded System
Pre-Wired with Audiomobile GT2 2010 Subwoofers
Two 10" Drivers. One Ported Enclosure. Wired And Ready To Run.
The Proline X Dual 10" Loaded System with Audiomobile GT2 2010 pairs two of Audiomobile's low-profile high-excursion 10" subwoofers with a Proline X ported enclosure built and assembled at our Tennessee facility. Net internal volume is 1.20 ft³ tuned to 37Hz via a 13.5 square inch slot port, calculated to match the GT2 2010's published vented alignment specs. Both drivers ship pre-installed and pre-wired to independent terminals at the cup, ready to connect to your amplifier.
This is the system for builds that want serious output and musical extension in a configuration that fits across full-size trunk floors and stays under most rear deck lines. At 29.5" wide, 15" deep, and 8.5" tall, the enclosure is full-size in plan view but compact in profile. Total system power handling is 800W RMS across both drivers.

Read This Before You Order: The Impedance Decision
The Audiomobile GT2 2010 is a single voice coil driver with a 3-ohm nominal voice coil (2.8Ω DCR actual). This is not a standard car audio impedance, and it has direct consequences for amplifier selection that need to be settled before you check out.
Parallel Wiring: 1.5 Ohms Nominal
Wiring both drivers in parallel at the amplifier terminals produces a 1.5 ohm nominal load (1.4 ohm DCR actual). This is below the 2-ohm minimum that most monoblock amplifiers are rated for. A 1-ohm-stable monoblock running 800W to 1000W RMS at 1 ohm handles the parallel load comfortably and delivers full power to both drivers.
Series Wiring: 6 Ohms Nominal
Wiring both drivers in series produces a 6 ohm nominal load (5.6 ohm DCR actual). Most monoblock amplifiers will run at 6 ohms, but power output drops significantly from the rated 1-ohm or 2-ohm figure. Plan on roughly 40 to 50 percent of the amplifier's 1-ohm rating at this load.
The Decision Point
Check your amplifier's minimum stable impedance before you check out. If it is 1-ohm stable, wire parallel and run full power. If it is 2-ohm stable only, wire series and plan for reduced output. If you have not selected an amplifier yet, a 1-ohm stable monoblock in the 800W to 1000W RMS range is the cleanest match for this system.
Why The GT2 2010 In A 1.20 ft³ Ported Chamber
Low-Profile Driver, Real-World Excursion
The GT2 2010's 4.2" mounting depth is shallow for a 10" subwoofer rated at 400W RMS. Most 10" drivers at this power class need 5" or more of mounting depth, which forces the enclosure designer into either a deeper cabinet or a smaller air chamber. The GT2's shallow depth lets the chamber stay properly sized for its alignment without compromising baffle thickness.
11.9mm One-Way Xmax
The GT2 2010 publishes 11.9mm one-way Xmax, which is real working displacement, not peak-to-peak math. In a 1.20 ft³ chamber tuned to 37Hz, the driver operates within its linear range across the bottom octave with margin to spare on transient peaks. This is what produces the musical character of this system, the drivers are not being pushed to their excursion limits to make output.
CLS Composite Sandwich Cone
The CLS Composite Sandwich cone is a multi-layer construction designed for stiffness-to-weight ratio. A stiffer cone resists breakup at the top of the bass band, which is where ported systems traditionally show the most coloration. The SBR rubber surround provides linear excursion control across the working range. The combination is a driver that stays composed at output levels where lesser drivers start adding their own signature to the music.
Construction: Langboard Elite MDF, V-Groove And Dado Joinery
Why Panel Rigidity Matters In A Ported Box
In a ported enclosure, panel rigidity directly affects port output. Any flex in the cabinet walls bleeds energy away from the port and into the structure. The result is soft, undefined bass at volume. This box does not flex.
Langboard Elite MDF, Mill-Certified
Every panel is cut from Langboard Elite MDF, 3/4" (18mm), a named, mill-documented panel stock produced in the United States. Specifications below are pulled directly from Langboard's published mill data.
| Density | 48.5 lbs/ft³ | Higher density means less porosity, better screw retention, reduced resonance |
| Internal Bond | 200 psi | Resistance to delamination under sustained ported pressure cycling |
| Modulus of Elasticity | 410,000 psi | Panel stiffness under load; less flex means more energy out the port |
| Face Screw Holding | 325 lbs | Baffle hardware stays locked under vibration |
| Edge Screw Holding | 250 lbs | Joint integrity at every panel edge connection |
V-Groove And Dado Joinery
Every panel joint uses V-groove and dado joinery, CNC-cut interlocking grooves that mechanically lock panels before adhesive is applied. Each mating panel is channeled into a mechanical lock before the bond cures, which eliminates the micro-gaps that develop in standard butt joint construction over time. On a ported enclosure that has to maintain a precise tuning frequency over the life of the build, joint integrity is not optional.
1.5" Double Baffle
The front baffle is 1.5" double-thickness, two layers of 3/4" Langboard Elite bonded face-to-face. The double baffle does two jobs at once: it provides the depth required to clear the GT2 2010's basket geometry on a recessed mount, and it eliminates baffle flex around the driver cutouts where the highest panel pressure occurs.
Proline X Terminal Cup, Built In Tennessee
Proline X ABS/carbon fiber terminal cup with stainless hardware and copper ring terminals. Built in-house at our Tennessee facility. Recessed mount keeps the cup protected from cargo contact. Both drivers wire to independent terminals on the cup, you set series or parallel externally at your amplifier. 12g OFC pre-installed.

The Audiomobile GT2 2010 is a low-profile 10" subwoofer built specifically for vented and small-box applications. Its 4.2" mounting depth and 11.9mm one-way Xmax make it a compact, high-excursion driver that performs in the airspace a dual ported configuration provides without requiring a full-size enclosure.
The GT2 series uses a CLS Composite Sandwich cone with SBR rubber surround, a powder-coated low-profile frame, and bi-radial-gap motor cooling vent technology. The driver runs a unique 3-ohm nominal voice coil design (2.8Ω DCR actual) that is not a standard car audio impedance. Read the impedance FAQ below before selecting your amplifier, this is the single most important purchase decision on this system.

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 — 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.
