We at CSS are so sure you’ll love our speakers and subwoofers that we offer a full 30 day return period on all products, regardless of whether they have been used or not. That means if you put together one of our crossovers and you don’t like the speaker, you can send it in for a full refund within 30 days the date your product was delivered.


For finished speakers, we offer a full 30 trial with free returns if you aren't happy with our product. We'll send you a shipping label and you ship us the items. Once the item is received and verified to be undamaged, you will receive a full refund including the original shipping cost.

For drivers and kits, if you aren’t happy with the product you’ve received for any reason, just ship it back to us. Once we receive the item and inspect for damage, you’ll receive a refund for the original purchase price, minus any shipping charges. For things like crossovers, we won’t consider soldered components damaged as long as the parts all function correctly. Any damaged non-working items will be deducted from the refund price. This offer does not apply to custom work.


All CSS branded items carry a 1 year warranty for defects. If you order a CSS branded component that is out of spec or malfunctioning, you can return it for a replacement or refund within 1 year of the original purchase date.
