Professional Series Sealed 10" Enclosure | Image Dynamics IDMAX10 V4
The IDMAX10 V4 pairs a heavy motor with a soft suspension, and Image Dynamics themselves recommend a sealed enclosure for it rather than a ported one. This cabinet holds 0.75 cubic feet net, landing the D2 coil at a Qtc of 1.01 and an Fc of 44.8 Hz. It is the single-driver sealed box in the professional Image Dynamics line, built to the tighter end of the range Image Dynamics themselves publish for this driver.

Why this driver is sealed
The IDMAX10 V4 pairs a heavy motor with a soft suspension, and Image Dynamics themselves recommend a sealed enclosure for it rather than a ported one. This cabinet holds 0.75 cubic feet net, landing the D2 coil at a Qtc of 1.01 and an Fc of 44.8 Hz. It is the single-driver sealed box in the professional Image Dynamics line, built to the tighter end of the range Image Dynamics themselves publish for this driver.
A Qtc of 1.01 is a tight, slightly peaked alignment: it trades away the last bit of low-end reach for a smaller box and a punchier sound with a mild lift near Fc, and it sits close to what Image Dynamics call their Universal tier for this driver. Their own manual lists three sealed volumes for the IDMAX10, a Compact box at 42 Hz, a Universal box at 39 Hz, and an Audiophile box at 37 Hz, all measured gross including the driver's own displacement. This cabinet's 0.75 cubic feet net comes out to a little under seven-eighths of a cubic foot gross, which lands between their Universal and Audiophile figures. F3 on this box works out to 35.0 Hz.
The alignment
0.750 cu ft net at Qtc 1.01, Fc 44.8 Hz, F3 35.0 Hz.
Polyfill is included, sized to the chamber. It is part of the alignment above, not packing material, so it should not be removed.
The cabinet
20.00" W x 13.00" H x 10.00" D external. It ships as a UPS parcel; the price includes shipping in the 48 states.
This is our single-ten sealed envelope for one IDMAX10, sized to the driver's frame and motor depth.
T/S for the IDMAX10 D2 come from loudspeakerdatabase.com's mirror of Image Dynamics' own coil-specific publication. Image Dynamics' own published Qes for this coil is inconsistent with their own Fs, Qts and Qms figures; the Qes carried in our data is derived from those three instead, at 0.704, rather than the number Image Dynamics print. Image Dynamics recommend a sealed box for the IDMAX10, and this cabinet is exactly that.

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. Full driver specifications are available at imagedynamicsusa.net.

Material
Built From a Spec Sheet, Not a Sales Sheet
Every Proline X Professional 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 Professional 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.
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.
