Cleaning

The cabinet surfaces of the M1 Active are covered with a vinyl laminate. Clean these
surfaces when necessary with a lint-free cloth dampened in warm soapy water. USE
ONLY A DRY CLOTH ON THE BACK PANEL OF THE POWER AMPLIFIER. Do
not attempt to clean the cabinet with a brush (which may damage the surface) or a
sponge (which may leave small crumbs in the texture).
Do not attempt to clean either of the drivers.
The M1 Active/Surround speakers require no periodic maintenance.
