Performance Optimized Wedge Sealed Dual 10" Enclosure NVX VCW10v3 · Dual 10" Sealed enclosure

The VCW10v3, yes, in either coil (VCW102v3 or VCW104v3). The baffle is cut to 9.65 in, NVX's published cutout, under the 11.06 in frame. The 6.30 inch motor clears the cabinet with 5.30 inch to spare. One cabinet serves both coils: the VCW102v3 (D2) reads Qtc 0.735 with half power at 34.5 Hz, and the VCW104v3 (D4) reads Qtc 0.680 at 42.5 Hz. Run two of the same coil so the chambers match.

Any other 10, no. The airspace is worked out from the VCW10v3's own Qts and Vas, and a different woofer that happened to drop into the hole would not see the alignment printed on this page.

1.20 cubic feet is split between the coils' Butterworth volumes (1.46 for the D2, 0.98 for the D4) on the D2 figures (Fs 27.3 Hz, Qts 0.56, Vas 24.5 liters): Qtc 0.735, half power at 34.5 Hz. One cabinet serves both coils: the VCW102v3 (D2) reads Qtc 0.735 with half power at 34.5 Hz, and the VCW104v3 (D4) reads Qtc 0.680 at 42.5 Hz.

NVX's manual and product pages are the only published source for this driver, so treat the Qtc as good to a few hundredths.

NVX rates the VCW10v3 at 1000 watts RMS per driver, so target 700 to 1000 watts RMS per driver at the final load.

A pair of VCW102v3 (D2) drivers can land on 0.5 ohm with all four coils in parallel, 2 ohms as series pairs in parallel, or 8 ohms all in series. A pair of VCW104v3 (D4) drivers can land on 1 ohm with all four coils in parallel, 4 ohms as series pairs in parallel, or 16 ohms all in series. Anything under 1 ohm, and many amplifiers at 1 ohm, is outside what the amplifier is built for; series wiring is the safe default. Confirm your amplifier's minimum stable impedance first.

The seat-side face carries a 20 degree rake that matches the lean of a factory rear seat back, so the cabinet sits flush against it and the cargo space in front stays usable. The baffle is the vertical trunk-lid-side face, so the drivers fire rearward into the trunk cavity.

The trunk acts as an acoustic extension for the sealed box, and the cabin adds real output below 50 Hz, so in-vehicle response runs deeper than the anechoic 34.5 Hz on this page.

Two drivers sharing one sealed volume load each other: each driver's compression stroke becomes the pressure the other works against, which blurs the alignment either would have alone. A bonded full-height 3/4 inch divider gives each driver its own 1.20 cubic feet and its own polyfill.

It also means a failure in one driver does not unload the other, and the alignment on this page is the alignment in each chamber, not an average across a shared box.

Anechoic F3 is 34.5 Hz per chamber on the D2, with system resonance at 35.8 Hz. Above Qtc 0.707 the response carries a small bump before the rolloff and F3 sits below fc.

Those figures exclude cabin gain. In a car the cabin's transfer function adds real output below 50 Hz, so in-vehicle response runs deeper than the numbers above.

No. Polyfill is already installed in both chambers as a light wall lining to control internal reflections, and the quantity is chosen so it does not change the acoustic volume.

Do not add more. Packing a sealed box with fill makes it behave as though it were larger, which walks the alignment away from the 1.20 cubic feet per chamber this cabinet was built to.

No driver. This is an enclosure only. You receive the cabinet finished in plush black carpet with the gloss black acrylic baffle insert, one side-mounted pre-wired terminal cup to both positions, the polyfill lining already in place, and threaded inserts pressed on NVX's published 10.24 inch bolt circle with stainless machine screws.

The pair of NVX VCW10v3 is purchased separately, and the cabinet is cut direct fit to it, not a general purpose 10 inch box.
