Warranty and Registration
Your EFX speakers are provided with an automatic Limited 90 Day
Warranty coverage. You have the option, at no additional charge,
to receive a Limited 5 Year Warranty coverage. To obtain the
Limited 5 Year Warranty coverage you need to complete and
return the Certificate of Registration, included with your speak-
ers, 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 EFX, speak-
ers you cannot be assured of having received new units. If this
is the case, please contact your authorized MartinLogan dealer.
Serial Number
EFX's serial number is located near the binding posts. Each individ-
ual unit has a unique serial number.
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 accordance
with its applicable warranty.
2 Should a MartinLogan product require servicing in a coun-
try other than the one in which it was originally purchased,
the end user may seek to have repairs performed by the near-
est MartinLogan distributor, subject to that distributor's local
servicing policies, but all cost of repairs (parts, labor, trans-
portation) must be born by the owner of the MartinLogan
product.
3 If, after owning your speakers for six months, you
relocate to a country other than the one in which you
purchased your speakers, your warranty may be transferable.
Contact MartinLogan for details.
