The NS v.5 is the absolute top-tier driver in Sundown's "ultra-high excursion" sub-woofer lineup with a 3” coil. All models (10,12,15,18) feature our custom tooled and patented frames (US Patent Numbers D691596, D691597, D691598, and D741841). Our proprietary frames allow 4” or more of peak-to-peak mechanical excursion.
From here the NS (Nightshade) line diverges dramatically from our other lines. The motor is based on our patented S.A.I.N.T. (Sundown Audio Intelligent Neodymium Technology) Design (US Patent Numbers US10382874B2 and USD791740S1). As of the release of the NS v.4/v.5 series these are the only products in our line to utilize this all new and proprietary design.
The Nightshade v.5 features an enormous 45mm (1.77”) magnetic gap to ensure the coil is always under control. This motor drives a 3" diameter 8-Layer Flat Wire Aluminum Coil with an extremely long winding (3.15” long) wound on a thick aluminum former to incredible levels of excursion.
