*To ensure a valid warranty, Polk loudspeakers must be purchased through an Authorized Polk home or car loudspeaker Dealer (such as Amazon.com). (If you’re not sure a dealer is “authorized,” call Polk at 1-800-377-7655, and ask us.) The warranty is not transferrable, that means it applies only to the original purchaser. If you purchase your speakers from a private individual, that product is considered “used” and has NO factory warranty, no matter what the seller implies. The warranty is VOID if the serial number of the speaker has been removed or defaced. If you have any questions about your warranty coverage, or you think you need service, call Polk Customer Service at 1-800-377-7655. We’re here to help you get the most from your new speakers!
