Proline X

Professional Series Sealed Dual 10" Enclosure | Image Dynamics IDMAX10 V4

Q: What makes this Professional rather than Performance Optimized?

The box. A Performance Optimized cabinet is cut to fit a trunk shape on a 1.5 inch double baffle; this one is a full-size front-firing box on a 2.25 inch triple baffle with the woofer flush-mounted in the outer layer, Image Dynamics logo acrylic. It carries a 2 year warranty against 1.

Q: Threaded inserts or a kit?

Threaded inserts pressed into the baffle on the published 10.528 inch bolt circle, stainless machine screws included. The inserts are in the baffle when it arrives; the machine screws are in the terminal cup bag.

Q: Do I need a subsonic filter?

Not for this sealed alignment; a 20 to 25 Hz high-pass only protects the driver from content below the cabinet's own roll-off.

Q: Would a ported version be better for me?

It depends what you want from it. A ported box gives up nothing above its tuning frequency and adds output below it, at the cost of a subsonic filter and a fixed vent length. This alignment is sealed at Qtc 1.01, F3 35.0 Hz, 0.750 cu ft per chamber: flatter group delay and a gentler rolloff, with less output at the very bottom of the band.

Q: How heavy is it and how does it ship?

35 lb, 28.00" W x 13.00" H x 12.00" D external. It ships as a UPS parcel; the price includes shipping in the 48 states. The box ships with polyfill installed; do not remove it.

Q: Is the IDMAX10 V4 included?

No. This is an enclosure only, cut for the Image Dynamics IDMAX10 V4 specifically: the 9.646 inch cutout and the 7.598 inch mounting depth allowance come from Image Dynamics's published parameters. Bring your own driver.

INSTALLER'S TAKE

This is the dual version of the sealed IDMAX10 box: two separate chambers, not one shared one, so each driver sees the same airspace the single gets.

Keeping the chambers isolated means one driver's motion does not pressurize the other's chamber, which is the point of building it this way instead of just doubling a shared box.

Wire the two D2 drivers series-parallel, the standard way to combine two dual-coil drivers into one sane load; check the result against what your amplifier is rated for.

It ships with polyfill inside each chamber, the way every sealed box in this line does. Set your high-pass filter between 20 and 25 Hz.

Product Details

Professional Series Sealed Dual 10" Enclosure | Image Dynamics IDMAX10 V4

Two IDMAX10 V4 drivers share this cabinet, each sealed into its own 0.75 cubic foot chamber rather than one shared airspace. Total net volume is 1.50 cubic feet, and each chamber lands its D2 coil at the same Qtc of 1.01 and Fc of 44.8 Hz as the single-driver box. It is the dual version of the sealed IDMAX10 enclosure, built for two isolated chambers rather than one shared box.

Sealed Qtc 1.01 F3 35.0 Hz Cut for the Image Dynamics IDMAX10 V4 Built in Tennessee

Why this driver is sealed

Each chamber gets the same 0.75 cubic feet Image Dynamics themselves recommend a sealed box for, isolated from its neighbor so the two drivers do not interact through a shared airspace. The Qtc of 1.01 per chamber is the same tight, slightly peaked alignment as the single-driver box: a compact, punchy sound that trades away the last bit of reach for size, sitting close to Image Dynamics' own Universal tier. F3 per chamber works out to 35.0 Hz, the same as the single.

The alignment

0.750 cu ft per chamber at Qtc 1.01, Fc 44.8 Hz, F3 35.0 Hz. Each of the two chambers is isolated.

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

28.00" W x 13.00" H x 12.00" D external. It ships as a UPS parcel; the price includes shipping in the 48 states.

This is our dual-ten sealed envelope, two isolated 0.75 cubic foot chambers for two IDMAX10 drivers in one cabinet.

T/S for the IDMAX10 D2 are the same coil-specific figures used in the single-driver sealed box, from loudspeakerdatabase.com's mirror of Image Dynamics' own publication; the D2's published Qes does not agree with Image Dynamics' own Fs, Qts and Qms, so the Qes used here, 0.704, is derived from those three instead. Scott's Q2 catalog sheet lists this cabinet 27 by 13 by eleven and a half inches; the store's 28 by 13 by 12 is what actually shipped and is the figure used here. Image Dynamics recommend a sealed box for the IDMAX10, and each chamber in this cabinet is built to that same 0.75 cubic foot figure.

Woofer Details

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.

Materials

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.
