Frequently Asked Questions

How do I clean my subwoofer?
Use a dust free cloth or a soft brush to clean your
subwoofer. We recommend a specialty cloth (available
through the Xtatic shop at www.martinlogan.com) that
cleans better than anything else we have tried.
Is it safe to set things on my subwoofer?
While your subwoofer is designed with a durable, stain-
resistant surface, we advise you not to set anything on
your subwoofer—especially containers holding liquids.
Is there likely to be any interaction between
my subwoofer and the television in my Audio/
Video system?
Yes. The subwoofer doesn't use a shielded driver. We
recommend 3 feet between the subwoofer and video
components that are susceptible to magnetic fields.
Plasma, LCD, and LED television are not susceptible to
magnetic interference.
Will my electric bill go 'sky high' by leaving my
subwoofer plugged in all the time?
No. When the power switch is set to 'Auto' the subwoofer
will draw about 15 watts when idle and only 10 watts in
standby mode.
Should I unplug my subwoofer during a thun-
derstorm?
Yes, or before. It's a good idea to disconnect all of your
audio/video components during stormy weather.

Hums or Unusual Sounds
