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 enclosure is built to order by Basshead Supply and ships direct from them in about 2 to 3 weeks.
- The subwoofers are not pre-installed. You mount them in the enclosure once both have arrived.
- The enclosure arrives finished in a gray stain, ready to install.
