Warranty & Repair
All OSD Audio speaker products have (5) year Limited Warranty against defects in materials and
workmanship. Proof of purchase must accompany all claims. During the warranty period OSD
will replace any defective part and correct any defect in workmanship without charge for either
parts or labor.
OSD Audio may replace returned speakers with a product of equal value and performance. In such
cases, some modifications to the mounting may be necessary and are not OSD’s responsibility.
For this warranty to apply, the unit must be installed and used according to its written instructions.
If necessary, repairs must be performed by OSD. The unit must be returned to OSD at the owner's
expense and with prior written permission. Accidental damage and shipping damage are not
considered defects, nor is damaged resulting from abuse or from servicing performed by an
agency or person not specifically authorized in writing by OSD.
OSD Audio sells products only through authorized dealers and distributors to ensure that custom-
ers obtain proper support and service. Any OSD product purchased from an unauthorized dealer
or other source, including retailers, mail over dealers and online sellers will not be honored or
serviced under existing OSD warranty policy. Any sale of product by an unauthorized source or
other manner not authorized by OSD shall void the warranty on the applicable product.
Damage to or destruction of components due to application of excessive power voids the warranty on
those parts. In these cases, repairs will be made on the basis of the retail value of the parts and labor. To
return for repairs, you must email customer service at RMA@osdaudio.com for a Returned Merchandise
Authorization (RMA) number# then the unit must be shipped to OSD at the owner's expense, along with
a note explaining the nature of service required. Be sure to pack the speaker(s) in a corrugated container
with at least 3 inches of resilient material to protect the unit from damage in transit.

Damage caused by abuse, accident, misuse, negligence, or improper operation (installation) • Any
products that have been altered or modified • Any product whose identifying number of decal,
serial #, etc. has been altered, defaced or removed • Normal wear and maintenance.
