Proline X Enclosure | Professional Series | Fits Image Dynamics IDMAX 10" Subwoofer
Single IDMAX 10 — One Driver, One Correctly Sized Box
The Image Dynamics IDMAX 10 V4 is a 19.5mm one-way Xmax driver rated at 1000 watts RMS. It rewards the right enclosure — and punishes the wrong one. This box was engineered around the IDMAX 10's published Thiele-Small parameters, spec'd to exactly 0.75 cu ft, and built with the structural integrity to stay accurate under sustained high-power use. Enclosure only. Driver not included.
Built exclusively for the Image Dynamics IDMAX 10 V4 (D2 or D4). Full driver specs at imagedynamicsusa.net.
Built to the Driver's Numbers — Not a Generic Template
Most sealed enclosures are designed to a safe universal volume that works acceptably with many drivers. This one isn't. The IDMAX 10 V4 has a published recommended sealed volume of 0.75 cu ft — and this enclosure delivers exactly that. Not 0.9 cu ft because it was easier to cut. Not 0.6 cu ft because it fit a standard box profile. 0.75 cu ft because that is what the driver was designed around.
The IDMAX 10 V4 carries a Qts of 0.44 (D4) to 0.50 (D2) — both squarely in sealed alignment territory. At 0.75 cu ft the system Q is controlled, transient response is fast, and the driver has the air volume it needs to operate at its mechanical limits without fighting the enclosure. This is the enclosure equivalent of running the correct amplifier gain — everything downstream performs better when the foundation is right.
1.5" Double-Layer Baffle with Threaded Inserts
The IDMAX 10 V4 generates significant motor force — 18.15 Tm BL factor, 19.5mm one-way Xmax, 1000 watts RMS. The front baffle carries the full mechanical load of that driver under sustained high-power use. This enclosure uses a 1.5" double-layer baffle — two full sheets of Langboard Elite MDF bonded and CNC-cut as a single unit — eliminating baffle flex as a variable entirely.
Threaded inserts are installed through the baffle and matched to the IDMAX 10's bolt pattern. The driver mounts with 8/32 machine screws — metal-to-metal threading, not wood screws into MDF. It doesn't loosen under vibration. It doesn't strip on remount. It stays torqued.
Dado + V-Groove Joinery | Extensive Internal Bracing
Every panel joint is CNC-cut to interlock before adhesive is applied. Dado joints recess each panel into its mating surface. V-groove cuts at panel edges create a mechanical lock that survives sustained pressurization cycles. Extensive internal bracing ties opposing walls and spans long panel runs — cabinet walls don't flex under load, airspace stays constant, and bass stays accurate.
Langboard Elite 3/4"
Mill-certified panel stock. 48.5 lbs/ft³ density, 200 psi internal bond, 410,000 psi MOE. Every panel traceable to published mill data.
Dado + V-Groove CNC
Panels interlock mechanically before adhesive is applied. The joint holds independent of glue — what you need from an enclosure running sustained high-power output.
Extensive Internal Bracing
Bracing ties opposing walls and spans panel runs that would otherwise flex. At 1000W RMS and 19.5mm one-way travel, panel resonance is eliminated at the source.
Proline X ABS/Carbon Fiber Terminal Cup
Built in-house. Stainless steel hardware. Copper ring terminals. Pre-wired 12-gauge OFC speaker wire to your selected impedance.
Wiring Options — D2 and D4
The IDMAX 10 V4 is available in Dual 2-ohm (D2) and Dual 4-ohm (D4). A single driver wires as follows:
D2 — voice coils parallel → 1Ω final load. Voice coils in series → 4Ω final load.
D4 — voice coils parallel → 2Ω final load. Voice coils in series → 8Ω final load.
The most common configurations for a single high-current amp are 1Ω (D2 parallel) and 2Ω (D4 parallel). Match to your amplifier's stable impedance rating before selecting a variant.
Every Proline X Professional Series enclosure is covered by a 2-year warranty against defects in materials and workmanship. Built in Tullahoma, Tennessee. Shipping included — no freight charges at checkout.

The Image Dynamics IDMAX 10 V4 is the driver this enclosure was built around — a 10" subwoofer engineered to deliver competition-grade output without sacrificing the tonal accuracy that SQ listening demands. With a BL factor of 18.15 Tm, 19.5mm of one-way linear Xmax, and 1000 watts RMS power handling, the IDMAX 10 V4 occupies a category of its own: a motor built for sustained high-power output paired with a lightweight pressed paper composite cone that maintains transient speed and accuracy at volume. Its Qts of 0.44–0.50 places it squarely in sealed alignment territory, making the 0.75 cu ft per chamber spec in this enclosure the correct target — not a compromise.

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.
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.
