What is covered in my warranty?

DS18's 2 Year Limited Warranty protects against flaws in the initial production of their purchased good(s). Any faults or defects in materials or workmanship that present themselves during the warranty period will be corrected right away.

Faults developed under the following circumstances are not covered by DS18’s warranty:

  • Damage resulting from falls, foreign item damage, etc.
  • Damage brought on by carelessness or abuse (including injury to returned goods from inadequate or bad packing).
  • Damage brought on by incorrect installation.
  • Damage caused by utilizing the product outside of the recommended parameters (for example, by overpowering speakers or subwoofers or by operating an amplifier below a 1 ohm load).
  • Damage brought on by distortion and/or clipping (improper tuning).
  • Products that seem to have been tampered with (modified or repaired products).
  • Theft.
  • Any item acquired via a DS18 unofficial dealer.

Item Abuse is a possibility and is classified as the repetitive returning of the same item with the same injury.

DS18 meticulously checks every returned item when evaluating whether a product is covered by warranty or not. Each returned product is extensively tested by DS18’s professional audio team to identify the root of the products malfunction. Based on the criteria above, DS18 holds complete discretion in deciding whether a product is covered by a warranty or not.

If a product is returned within two years of purchase and determined to be faulty according to our warranty guidelines, it will be replaced. DS18’s Return Policy may apply differently under Products purchased within 30 days, depending on their place of purchase.

Any item(s) qualified for warranty coverage may be replaced by DS18 with a device that has been reconditioned and is of equivalent quality. DS18 maintains the right to substitute the model of product that is most comparable to the original product in lieu of discontinued items that are being replaced under warranty.

We do everything we can to make sure you receive your items as soon as possible: however, in most circumstances, the claim is resolved within 48 hours. We ask that you give us 3 to 5 business days from the date of arrival at our facility for product testing and settlement of your claim.
