Performance Optimized Wedge Sealed 10" Enclosure NVX NSW10v3 · Single 10" Sealed enclosure

The NSW10v3, yes, in either coil (NSW102v3 or NSW104v3). The baffle is cut to 8.97 in, NVX's published cutout, under the 10.40 in frame. The 5.36 inch motor clears the cabinet with 0.75 inch to spare. One cabinet serves both coils: the NSW102v3 (D2) reads Qtc 0.684 with half power at 53.7 Hz, and the NSW104v3 (D4) reads Qtc 0.729 at 48.4 Hz.

Any other 10, no. The airspace is worked out from the NSW10v3'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.

0.77 cubic feet is split between the coils' Butterworth volumes (0.67 for the D2, 0.88 for the D4) on the D2 figures (Fs 38.7 Hz, Qts 0.51, Vas 17.4 liters): Qtc 0.684, half power at 53.7 Hz. One cabinet serves both coils: the NSW102v3 (D2) reads Qtc 0.684 with half power at 53.7 Hz, and the NSW104v3 (D4) reads Qtc 0.729 at 48.4 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 NSW10v3 at 500 watts RMS, so target 350 to 500 watts RMS at the final load.

The NSW102v3 (D2) wires to 4 ohms with its coils in series or 1 ohm in parallel. The NSW104v3 (D4) wires to 8 ohms in series or 2 ohms in parallel. 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 driver fires 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 53.7 Hz on this page.

The baffle is two bonded 3/4 inch sheets, 1.5 inches through. A single 3/4 inch panel flexes under the pressure a 10 inch woofer puts on it at 500 watts, which smears output and works the driver loose over time; the second layer stiffens the face and gives the mounting hardware twice the material to bite.

The outer layer is machined as a flush recess to the 10.40 inch frame, so the driver bolts to the inner layer and sits flush with the gloss black acrylic insert.

Anechoic F3 is 53.7 Hz on the D2, with system resonance at 51.8 Hz. Below Qtc 0.707 the rolloff is gentle and F3 sits above fc, which is what a damped sealed box does.

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 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 0.77 cubic feet 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, the polyfill lining already in place, and threaded inserts pressed on NVX's published 9.68 inch bolt circle with stainless machine screws.

The NVX NSW10v3 is purchased separately, and the cabinet is cut direct fit to it, not a general purpose 10 inch box.
