Sundown Audio SA Series 15″ Dual 2-Ohm VC Subwoofer 2000 Watt Peak SA-15-V2-D2

We started with a larger, more powerful motor to drive the larger 2.75″ coil and stronger soft parts; this maintains the perfect balance of the original SA series while also increasing the power handling to 1000-watts RMS. FEA optimized motor & coil design capable of 19mm of one-way linear excursion by 70% BL and just over 35mm of x-mech. This motor & coil setup was then mated up to an extremely robust double-layer spider with fully tied-on & doubled-up XL tinsel leads (84-Strands of Conductor per lead), an SPL competition grade paper cone, and a strong foam surround. The motor also features a large magnet ID shorting ring (faraday ring) to reduce distortion causes by inductance & inductance variation over stroke. This system allows our 2.75″ coil to match and exceed the thermal performance of many competing 3″ coil drivers on the market without requiring the usage of a much heavier voice coil.
