Description

SA v.2 15" Subwoofer

RMS 1000 watts

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

This 12” SA v.2 is a top-down upgrade. The 2.75” coil punches way above its weight, outperforming most 3” coils without adding weight. 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 & 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.
