Sundown Audio SA v2 18 Single 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: (1) Sundown Audio SA-Series v.2 18" Subwoofer
The SA v.2 18" is a top-down upgrade of the original SA series, handling 1250 watts RMS / 2500 watts peak. Its 2.75" aluminum-former coil punches above its weight, outperforming many 3" coils without the added mass while allowing a wider spider. A large magnet shorting (Faraday) ring reduces distortion for smoother response across the spectrum, and a vented magnetic gap and pole piece keep the coil cool. The motor and coil mate to a robust multi-layer spider with doubled-up XL tinsel leads, a competition-grade paper cone, strong foam surround, and cast-aluminum frame. With ~19mm of one-way linear excursion and a 37mm x-mech limit, the 18" uses a larger-diameter motor to drive its higher mass.
Features
- Aluminum 2.75" voice coil former for superior heat dissipation
- Vented magnetic gap and pole piece
- Magnet ID Faraday ring for smooth acoustic response
- High-velocity cast-aluminum vented frame spacer ring
- Spring-loaded terminals with stitched-on double XL tinsel leads
