This Listing Includes: (1) Sundown Audio SA-Series v.2 10" Subwoofer
The SA v.2 is a top-down upgrade from the original SA series, built around a 2.75" aluminum-former coil that punches above its weight and outperforms many 3" coils without the added mass. Sundown balanced the moving mass, motor force, and suspension stiffness for the intended power level, and added a large magnet shorting (faraday) ring to reduce distortion and smooth response across the acoustic spectrum. The coil mates to a robust multi-layer spider with fully tied-on, doubled-up XL tinsel leads, while a competition-grade paper cone, foam surround, and cast aluminum frame complete the build. With ~19mm of one-way linear excursion and a 37mm x-mech limit before coil bottom, it is nearly bottomless at 1250W RMS (2500W peak). Authorized Sundown Audio dealer at JS Ultimate Sounds. Free shipping on orders $99+.
