Sundown Audio SA v2 12 Dual Bundle (Baltic Birch)
Many in-stock orders ship within 1-2 business days, but timing varies by item. Custom, built-to-order, oversized, special-order, and supplier-direct products may need extra processing time. Free shipping applies to qualifying orders over $99 within the contiguous US. Freight items may require delivery coordination; any shipping exceptions are shown before checkout. Approved returns may be subject to a restocking fee.
Most products are covered by the manufacturer's warranty against defects. Damage from over-powering or improper installation isn't covered — we'll help coordinate any valid claim.

This Listing Includes: (2) Sundown Audio SA-Series v.2 12" Subwoofers
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).
Features
- Aluminum 2.75" voice coil former for superior heat dissipation
- Magnet ID faraday ring for smooth acoustic response
- High-velocity cast aluminum vented frame spacer ring
- High-temperature copper voice coil wire with spring-loaded terminals
- Stitched-on double XL tinsel leads
