SA-Series v.2 18" Subwoofer
1250 Watts RMS / 2500 Watts Peak Dual 2 or 4 ohm voice coils Vented magnetic gap Aluminum 2.75” voice coil former for superior heat dissipation Innovative high-velocity vented frame spacer ring Large aluminum Faraday ring for smooth acoustic response Patented high-strength cast aluminum frame High-temperature voice coil wire Spring-loaded terminals Stitched-on double “XL” tinsel lead wires 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 us
