ZV6-15 D1

The ZV6-15 D1 is a 15-inch ultra-high-excursion subwoofer rated 3250W RMS and 6500W peak, sitting one step above the X v.3 series and replacing the Z v.5. Xmax is 35mm one-way measured at 70 percent BL, and the motor has enough clearance for over four inches of peak-to-peak travel before mechanical bottom.

That motor is a quad-stacked 240mm structure with a 100mm total magnet stack and a hyper-extended pole. Both the top and back plates are thicker than the X v.3, and the top plate is another 5mm thicker than the outgoing Z v.5, which adds magnetic strength and excursion potential. It moves a 3" black aluminum 8-layer flat wire voice coil, an upgrade from the 4-layer coil in the v.5 that raises motor force and output.

Cooling comes from a high-velocity pole vent, a heavily vented magnetic gap, and machined channels in four places around the pole piece, plus a cast-aluminum vented frame spacer ring. The patented custom-tooled basket, Mega-Roll v.2 surround, ultra-linear spider packs, large aluminum Faraday ring, and stitched-on XL tinsel leads round out the build.

The Z v.6 targets the lowest bass extension possible from a small ported box while keeping distortion low. Recommended volume is 4 cu ft with 60 sq in of port area tuned to 32Hz, and it will also work in an enclosure up to 50 percent larger for more extension. A sealed box is not recommended. Mounting depth is 12.93" with a 13.93" cutout, and dual 1-ohm coils wire to a 0.5-ohm or 2-ohm load.
