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.

How this package ships
- Two separate deliveries. Your subwoofer ships from JS Ultimate Sounds and usually arrives first.
- Separate tracking numbers. You will get one for each delivery, so a tracking link showing only part of your order is normal.
- The enclosure is built to order by Basshead Supply and ships direct from them in about 2 to 3 weeks.
- The subwoofer is not pre-installed. You mount it in the enclosure once both have arrived.
- The enclosure arrives bare and sanded, ready for you to finish however you like.
