This warranty is valid only for the ORIGINAL PURCHASER and is not extended to owners of the product subsequent to the original purchaser. Any applicable implied warranties are limited in duration to a period of the express warranty as provided herein beginning with the date of the original purchase at retail, and no warranties, whether express or implied, shall apply to this product thereafter.

KEEP ALL PACKAGING MATERIALS. Speakers not returned in their original packaging will be charged a repackaging fee when they are repaired and returned. Defective merchandise should be returned to teamSPB for warranty. Package all defective items in the original container or in a package that will prevent shipping damage. Failure to return the merchandise in its original packaging will result in a new packaging/handling charge being processed at the time the product is shipped back to you. Freight must be prepaid; items sent freight collect, or COD, will be refused. If the product sent for warranty service is found defective under our warranty policy, we will return the product freight prepaid to you. If the product is not covered under warranty, you will be notified of the repair and shipping costs and said costs must be paid before any service is made on the product.

Failure to follow these steps may void your warranty. Any questions can be directed to the sales department.

All of our products are capable of producing sound levels that can permanently damage your hearing! Turning up a system to a level that has audible distortion is more damaging to your ears than listening to an undistorted system at the same volume level. The threshold of pain is always an indicator that the sound level is too loud and may permanently damage your hearing. Please use common sense when controlling volume!
