Your Grotto subwoofer is provided with an automatic Limited
90 Day Warranty coverage.
You have the option, at no additional charge, to receive
Limited 3-Year Warranty coverage. To obtain the Limited
3-Year Warranty coverage you need to complete and return
the Certificate of Registration, included with your subwoofer,
and provide a copy of your dealer receipt, to MartinLogan
within 30 days of purchase.
For your convenience MartinLogan also offers online warranty
registration at www.martinlogan.com.
MartinLogan may not honor warranty service claims unless
we have a completed Warranty Registration card on file!
If you did not receive a Certificate of Registration with your
new Grotto subwoofer you cannot be assured of having
received a new unit. If this is the case, please contact your
authorized MartinLogan dealer.
Service
Should you be using your MartinLogan product in a country
other than the one in which it was originally purchased,
we ask that you note the following:
1 The appointed MartinLogan distributor for any given
country is responsible for warranty servicing only on units
distributed by or through it in that country in accor-
dance with its applicable warranty.
2 Should a MartinLogan product require servicing in a
country other than the one in which it was originally
purchased, the end user may seek to have repairs per-
formed by the nearest MartinLogan distributor, subject
to that distributor's local servicing policies, but all cost
of repairs (parts, labor, transportation) must be born by
the owner of the MartinLogan product.
3 If, after owning your subwoofer for six months, you relocate
to a country other than the one in which you purchased
your subwoofer, your warranty may be transferable.
Contact MartinLogan for details.
