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 Sundown Audio InHuman is a limited-edition 18" built for extreme SPL — 6th-order bandpass demo builds and competition walls. It rides a quad-stack 330 mm ferrite-and-neo motor on Sundown's patented tooled frame, with a custom-tooled carbon fiber cone and a 5" eight-layer flat-wound aluminum voice coil.
At nearly 190 lb it requires motor support in the enclosure.
