How do I clean my speakers?
Use a dust free cloth (such as a micro fiber cloth)
or a soft brush to remove dust from your speakers.
Do not spray any kind of cleaning agent on or in
close proximity to the drivers.
Could you suggest a list of suitable elec-
tronics and cables ideal for MartinLogan
speakers?
We have no favorites and use electronics and
cables quite interchangeably. We would suggest
listening to a number of brands—and above all
else—trust your ears. Dealers are always the best
source for information when purchasing additional
audio equipment.
Will exposure to sunlight affect the life
or performance of my speakers?
We recommend against placing any loudspeaker
in direct sunlight. Ultraviolet (UV) rays from the sun
can cause deterioration of cabinet, speaker cones,
etc. Small exposures to UV will not cause a prob-
lem. Filtering of UV rays through glass will greatly
reduce the negative effects.
Should I use a 4, 6, or 8 Ohm rated
amplifier with my speakers?
All of our Motion®series speakers are compatible
with 4, 6 or 8 Ohm output audio amplifiers and
receivers. Many of the most popular brands of AV
receivers and amplifiers with 4, 6 and 8 Ohm out-
put ratings have been thoroughly tested with all of
our products and we have found no compatibility
issues except under extreme listening conditions.
For the best performance and sonic purity when
using our Motion®series products use of an ampli-
fier or AV receiver with either a 4 or 6
Ohm output is recommended!

er, directly beneath the binding posts. The serial
number may also be found on the product carton.
SERVICE
Should you use 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 coun-
try in accordance with its applicable warranty.
2 Should a MartinLogan product require ser-
vicing 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 distribu-
tor’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.
