Performance Optimized Wedge Sealed 10" Enclosure | Kicker Comp VX 10
The Performance Optimized Wedge Sealed 10" Enclosure for the Kicker Comp VX 10 is a musical sealed cabinet built around Kicker's high-output round subwoofer. Comp VX sits one step below the flagship CompQ in Kicker's SQ lineup, offering nearly identical build quality and output character at a more accessible price point.
The Kicker Comp VX 10 (50CVX102 DVC 2Ω or 50CVX104 DVC 4Ω) is a 600-watt RMS subwoofer with 16.25mm of one-way Xmax, a SoloKon polypropylene cone with vented back bracing, ribbed Santoprene surround, cast aluminum basket with perimeter venting, UniPlate extended pole piece for heat dissipation, and Kicker's high-strength suspension. It's built on the same platform philosophy as the Solo-Baric L7 line, using the same core technologies scaled to fit a round subwoofer designed for musical output.
The 0.80 cubic foot net volume matches Kicker's own recommended minimum sealed enclosure and produces a Qtc of 0.63 based on bench-measured T/S parameters. This is an extended musical alignment that gives the Comp VX 10 room to breathe, delivering deep low-end reach with excellent midbass articulation. Predicted F3 lands at 65 Hz, with strong cabin gain typical of trunk installations extending that meaningfully lower in-vehicle.
Construction is the full Proline X Performance Optimized platform: ShopSabre CNC-cut Langboard Elite MDF stack-fab layers, all four corners radiused 3" viewed top-down, precision-milled magnet cavity for volume tuning and voice-coil cooling, perimeter cross-bracing, and a double-layer 1.5" front baffle (two 3/4" MDF sheets bonded) for maximum baffle rigidity and driver isolation. Wedge geometry angles the cone rear-firing into the trunk at ~20° from vertical for optimum cabin loading. Terminal cup is our Proline X ABS/carbon-fiber composite pre-wired with 12 gauge OFC.
Bring your own Kicker Comp VX 10 — mount cutout is direct-fit for either the 50CVX102 or 50CVX104.

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.
