The DiamondBoxx Enclosure
Limited Warranty
If you need service on your DiamondBoxx:
To obtain service worldwide please e-mail
DiamondBoxx at
[e-mail]
All warranty returns should be sent to DiamondBoxx in the original packaging (so it doesn't get more
damaged on its way to us) accompanied by proof of purchase (a copy of the original sales receipt).
Warranty expiration on products returned without proof of purchase will be determined from the
manufacturing date code. Non-defective items received will be returned COD. Customer is
responsible for shipping charges and insurance in sending the product to DiamondBoxx. Shipping
damage on returns is not covered under warranty, USE ORIGINAL PACKAGING
The enclosure is made from Medium Density Fiberboard (MDF). This is what most great sounding
are made from. No plastic. As such, it is difficult to manufacture any crazy curvy shapes as
possible with, but it SOUNDS better. Isn't that the point? The DiamondBoxx enclosure is sealed
using DURATEX speaker coating that will provide years of protection. If it should ever get
damaged beyond your liking by knocking it into things, dropping it, scratching it and such, all is not
lost. You can send it to us in the ORIGINAL PACKING or equivalent and we can replace the
enclosure for a small fee. As they are all hand built and rolled it is normal for there to be slight
inconsistencies in the finish. Consider them like beauty marks, specific to your DiamondBoxx. To
clean just wipe down with a water dampened cloth.
Happy Listening!
