Sundown Audio NS-10 V.3 D2 10" 2500W RMS Dual 2-Ohm Nightshade V3 Series Subwoofer

The Nightshade v.3 is the premium 3 inch coil "ultra-high excursion" subwoofer in our lineup. The 10, 12, 15, and 18” models feature our custom tooled and patented frames. Sundown only offers the Nightshade v.3 with our custom tooled 18” frame as it is too heavy for the traditional 6-spoke frame to reliably support.

We mate these new platforms to a QUAD stacked 250mm (9.84”) diameter motor structure featuring a hyper-extended pole and extreme clearances (allowing up to 4" p-p travel before mechanical bottom). The Nightshade features an enormous 45mm (1.77”) thick top plate to ensure the coil is always well within the magnetic gap. This motor drives a 3" diameter 4-Layer Flat Wire Aluminum Coil with an extremely long winding (3.15” long winding) wound on a thick aluminum former to incredible levels of excursion. We use 100% American made voice coils & build each unit in-house here in North Carolina as ordered.

The Nightshade v.3 features the longest coil of any 3” coil speaker we have made to date. We leveraged the advantage of the huge motor of the Nightshade v.3 so we could take advantage of an extremely long 4-layer coil – the 4-layer coil keeps the mass and inductance down while allowing us to use such a long coil for incredible linear x-max while the huge motor allows us to achieve the level of BL we desired.
