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.

The SA 8-inch is the pinnacle of low-distortion ported-box subwoofer technology, completely custom tooled with a full 16mm of one-way linear excursion and mechanical capacity exceeding double the linear limits for durability and low distortion. A large aluminum faraday ring smooths acoustic response while the low-distortion motor handles 600W RMS (1200W peak) across dual 2 or 4 ohm coils. The v.3 update adds a new surround with linear geometry and improved thermal performance via 16 chamfered gap vents that keep high-velocity air flowing over the voice coil.
