Performance Optimized Wedge Wide Sealed Triple 10" Enclosure | Kicker CompC10 DVC

Q: Does this fit the Kicker CompC10 DVC, and its coil versions?

Yes. Each opening is cut to 9.188 in for the 10.6875 in frame, and the 5.19 in deep motor clears the raked rear panel with 3.88 in to spare. Coil versions of the Kicker CompC10 DVC share the frame, cutout and mounting depth, so any of them drops in. The alignment on this page is computed on the CompC10 (CWCD104) parameters.Run three matched drivers, same model and same coil, so every chamber sees the alignment on this page.

Q: Why 0.985 cubic feet per driver, and what alignment does it target?

On Kicker's published Fs 34.0 Hz, Qts 0.696 and Vas 41.8 liters, 0.985 cubic feet per driver gives Qtc 1.100, system resonance 53.7 Hz and half power 40.6 Hz.The maker's minimum sealed size is 0.97 cubic feet per driver; this cabinet stops at 0.985, where Qtc reaches 1.1, so it stays compact without going past a pronounced lift near resonance, 1.8 dB above flat.

Q: What amplifier power should I run, and how should I wire it?

Kicker rates the CompC10 DVC at 250 watts RMS per driver. Recommended amplifier: 180 to 250 W RMS per driver, 540 to 750 W RMS for the full set of 3.Each CompC10 (CWCD104) has two 4 ohm voice coils, 8 ohms in series or 2 ohms in parallel. With each driver's coils in series and the three cups in parallel, the three present 2.67 ohms to a mono amplifier. With each driver's coils in parallel and the three in series, they present 6 ohms. Three drivers do not reach the round loads a pair does, so check the result against your amplifier's minimum stable impedance before powering up.

Q: Why are all three terminal cups on the back?

Each driver has its own sealed chamber, and the center chamber has no side wall to take a cup. Putting all three on the rear panel gives a matching set, one cup per chamber.Wire them at the amplifier end; there is no cross-chamber wiring inside the cabinet.

Q: What is the expected low-frequency extension?

Anechoic F3 is 40.6 Hz per driver with system resonance at 53.7 Hz.Those figures exclude cabin gain. An SUV cabin adds real output below about 50 Hz, so in-vehicle response runs deeper than the numbers above.

Q: Do I need to add polyfill or damping?

No. Polyfill is already installed as a light wall lining in every chamber, and the quantity is chosen so it does not change the acoustic volume.Do not add more. Packing a sealed box makes it behave as though it were larger, which moves the alignment away from 0.985 cubic feet per driver.

Q: Are the drivers included?

No. This is an enclosure only. You receive the cabinet finished in plush black carpet with the gloss black acrylic baffle insert, three pre-wired terminal cups on the rear panel, the polyfill lining in place, threaded inserts and stainless machine screws.Bring three matched Kicker CompC10 DVC drivers. The cabinet is cut direct fit to them, not a general purpose 10 inch box.

INSTALLER'S TAKE

Start with the size. The maker's minimum sealed size calls for 0.97 per driver; we stop at 0.985, where Qtc reaches 1.1. 0.985 cubic feet per driver puts the CompC10 DVC at Qtc 1.100, resonance 53.7 Hz, half power 40.6 Hz anechoic, a pronounced lift near resonance, 1.8 dB above flat.

Measure the base depth, not the top. This cabinet is 15.56 in deep where it meets the floor, 9.37 at the top, 40 wide and 17 tall. In an SUV the 40 has to clear between the rear wheel wells at floor height, the base depth is measured from the seat back with the seat upright and latched, and the 17 has to clear the cargo cover.

All three terminal cups are on the rear panel, and the rear panel is the face that goes against the seat back. Wire all three before the box goes in, with enough slack to slide it into place; once the raked face is against the seat you cannot reach them.

Impedance. CompC10 (CWCD104): wire for 2.67 ohms (coils in series, the three cups in parallel), the load most monoblocks are built to deliver full power into; 6 ohms is the other clean option (coils in parallel, the three in series). Work the load out before you buy the amplifier, not after.

Power. Size the amplifier for the set, not one driver: 180 to 250 W RMS per driver is 540 to 750 W RMS across all 3 at 2.67 ohms.

Kicker's Qes and Qms reproduce the printed Qts within 3 percent, so the alignment rests on a self-consistent set.

Polyfill is in as a wall lining in every chamber. Do not add more: it makes the box act larger and walks Qtc off 1.10.

Three Kicker CompC10 DVC in a 40 Inch Sealed Wedge

The wide wedge is a fixed SUV platform: 40 inches across and 17 tall, built to span a cargo floor against the rear seat. Depth is the only dimension that moves, and it is solved for the driver. Here it runs 9.37 in at the top to 15.56 in at the base.

0.985 cubic feet net per driver on Kicker's published Fs 34.0 Hz, Qts 0.696 and Vas 41.8 liters: Qtc 1.100, system resonance 53.7 Hz, half power 40.6 Hz. The maker's minimum sealed size is 0.97 cubic feet per driver; this cabinet stops at 0.985, where Qtc reaches 1.1, so it stays compact without going past a pronounced lift near resonance, 1.8 dB above flat.

Three Fully Separate Chambers

Two bonded full-height 3/4 inch MDF dividers split the cabinet into three sealed chambers of 0.985 cubic feet net, one driver each, so no driver loads another. Three pre-wired terminal cups on the rear panel, one per chamber. The center chamber has no side wall, so all three cups go on the back for a matching set.

Cargo-Floor Wedge Design

The woofers mount on the vertical face and fire rearward toward the liftgate. The raked face goes against the rear seat back.

Raked Face Matches the Seat

A 20 degree rear panel follows the lean of a rear seat back.

40 Inches Across

Built to span a cargo floor. Measure between the rear wheel wells.

17 Inches Tall

Check it against your cargo cover and rear glass before you order.

Wiring Three Kicker CompC10 DVC to Your Amplifier

Each CompC10 (CWCD104) has two 4 ohm voice coils, 8 ohms in series or 2 ohms in parallel. With each driver's coils in series and the three cups in parallel, the three present 2.67 ohms to a mono amplifier. With each driver's coils in parallel and the three in series, they present 6 ohms. Three drivers do not reach the round loads a pair does, so check the result against your amplifier's minimum stable impedance before powering up.

Kicker rates the driver at 250 watts RMS each, 750 across all three. Recommended amplifier: 180 to 250 W RMS per driver, 540 to 750 W RMS for the full set of 3.

Built in Tennessee, Backed by Audio Intensity

Cut and assembled in Tullahoma, Tennessee on our own CNC equipment. Finished in plush black carpet with the gloss black acrylic baffle insert, three pre-wired terminal cups on the rear panel, 12 gauge OFC. Polyfill wall lining installed in every chamber.

W RMS recommended

This enclosure holds 0.985 cu ft net per driver. In it the Kicker CompC10 (CWCD104) runs a system Qtc of 1.10 with half power at 40.6 Hz, and the cone reaches its 13.15 mm travel limit at 258 W per driver, above the driver’s 250 W thermal rating, so heat stops you before travel does. A 25 Hz subsonic filter adds little here: 262 W per driver against 258 W, 2 percent. The box already resonates at 54 Hz, so its own rolloff has removed most of what the filter would have stopped.

00Sizing the amplifier

Every wattage on this panel is per driver. This cabinet holds three, so the amplifier feeds all three at once.

Per driver 180–250 W RMS × 3 drivers = full set 540–750 W RMS at 2.67 ohms

Look for a mono amplifier rated 540–750 W RMS at 2.67 ohms, the load the set wires to most easily. The top is the driver’s 250 W thermal rating; with the 25 Hz subsonic set the cone still has travel to spare there, reaching Xmax only at 262 W. Below the bottom of the range it will play, just with less headroom; above the top you are buying power the drivers cannot use.

01Is it a sealed driver?

Efficiency bandwidth product places the motor before anything else is decided.

EBP = Fs ÷ Qes = 43.9

Dual 4 Ohm · EBP 43.9

EBP under 50 means a motor that wants a sealed load. The CompC10 (CWCD104) sits at 43.9, inside that band, which is why this is a sealed build rather than a ported one.

02What the box does to it

0.985 cu ft against a 41.8 L Vas.

α = Vas ÷ Vb = 1.50 · Fc = Fs√(α+1) = 54 Hz · Qtc = 1.10

Dual 4 Ohm · Qtc 1.10, Fc 54 Hz, F3 40.6 Hz

The box lifts resonance from 34.0 Hz free-air to 54 Hz and half power lands at 40.6 Hz, anechoic, before any cabin gain. Figures are Kicker’s published parameters; Qes and Qms reproduce the printed Qts. This cabinet holds three drivers in three separate sealed chambers of 0.985 cubic feet each, the volume plotted here.

03The watts that reach Xmax (in this enclosure)

Travel scales with the square root of power, so there is one wattage that puts the cone exactly on 13.15 mm, and in this alignment a subsonic filter barely moves it.

P_Xmax = 258 W per driver unfiltered → 262 W per driver with a 25 Hz subsonic

Dual 4 Ohm · 258 W, no filterDual 4 Ohm · 262 W with subsonic at 25 Hz, 24 dB/octXmax 13.15 mm one-way

Every trace touches the limit and no further, because each is drawn at the exact power that puts that coil on 13.15 mm. Unfiltered that is 258 W per driver, reached first at 41 Hz. It sits above the 250 W the driver can take thermally, so the voice coil gives up before the suspension does. The dashed traces are the same driver behind a subsonic filter at 25 Hz, 24 dB/oct, and they sit almost on top of the solid ones: 262 W per driver against 258 W. At 54 Hz the filter sits well below resonance, where the sealed alignment has already rolled the cone off at 12 dB/oct, so there is little wasted travel left for it to recover. Set it anyway to keep road rumble out of the cone, but do not size the amplifier around it.

Materials

Material

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.

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 Performance 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.
