Your Stage speaker is 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 cover-
age you need to complete and return the Certificate of 
Registration, included with your speaker, 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 Stage speaker you cannot be assured of having 
received new units. If this is the case, please contact your 
authorized MartinLogan dealer.

Stage’s serial number is located near the binding posts.
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 country other than the one in which it was origi-
nally purchased, the end user may seek to have repairs 
performed by the nearest MartinLogan distributor, sub-
ject to that distributor’s local servicing policies, but all 
cost of repairs (parts, labor, transportation) must be 
borne by the owner of the MartinLogan product.
3 If, after owning your speaker for six months, you
relocate to a country other than the one in which 
you purchased your speaker, your warranty may be 
transferable. Contact MartinLogan for details.
