Warranty Service on ProBox Subs

In order for ProBox subs to be eligible for warranty service, please cut or tear out the paper cone, and then provide a photo of your sub clearly showing the following:

  1. the part number on the back of the magnet
  2. that you have cut or torn out the cone
  3. the date code stamp on the rim of the basket

Once eligibility for warranty service has been confirmed, ProBox will grant a one-time replacement of the sub. The date code will be stamped with an "R" to show that it has been replaced.
