A top-down improvement from previous models, the SA 18-inch sub features the largest motor in the series, now delivering over 35mm of mechanical excursion. The 2.75” coil punches way above its weight, outperforming most 3” coils without adding mass. The motor also features a large magnet shorting ring (faraday ring) to reduce distortion and deliver smoother response across the entire acoustic spectrum. The motor and coil setup is mated to an extremely robust double-layer spider with fully tied-on & doubled-up “XL” tinsel leads. A competition-grade paper cone and a strong foam surround were used to complete this masterpiece.
