Description
The Sundown Audio SA Series, including the Sundown Audio SA18 v.2, is Sundown Audio's top selling series! The new v.2 version features a larger, more powerful motor to drive the larger 2.75-inch coil and stronger centering - maintaining the perfect balance of the original SA Series while increasing the power handling to 1000 watts RMS.
The Sundown Audio SA18 v.2 has a linear excursion (XMAX) of 19 mm which allows slightly more than 35 mm x-mech. The motor also features a large magnetic ID shorting ring (Faraday ring) to reduce distortion caused by inductance and inductance variations across the excursion.
The 18-inch model has a larger motor than the SA-10/12/15 v2 with a diameter of 205 mm and a magnetic gap height of 60 mm. It has a large 234 mm diameter centering spider pack for a very high mechanical lifting capacity. It uses the same 2.75″ coil as the other subwoofers in the SA v.2 series for a rated output of 1000 watts RMS.
