WARRANTY AND REGISTRATION
Your EM-ESL C 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. For 
your convenience MartinLogan offers online war-
ranty registration at www.martinlogan.com.
MartinLogan may not honor warranty service 
claims unless we have a completed warranty regis-
tration on file! Please retain a copy of your receipt. 
The receipt may be required should you require 
service in the future.
SERIAL NUMBER
EM-ESL C’s serial number is located near the 
binding posts. Each individual 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 country other than the one in 
which it was originally purchased, the end user 
may seek to have repairs performed 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 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.

of Highs’.
Lack of Bass, No Bass
•  Check your speaker wires. Is the polarity 
correct?
• Check the binding posts. Are the dirty? If so 
clean them with rubbing alcohol.
• Check the binding posts. Are the loose? Make 
sure they are firmly hand-tightened.
