5. MAINTENANCE AND CLEANING
The loudspeakers do not require any particular maintenance operations, just general periodic
cleaning.
It is recommended to use a soft brush to eliminate any dust that may have accumulated on
the cabinet, the front panels, and the loudspeakers themselves, taking care not to damage the
loudspeakers' delicate membranes.
It is recommended to use the supplied cloth and liquid to clean the metal and glass surfaces (where
present). Do not use aggressive strong chemical products such as acetone, trichloroethylene, acids,
abrasive agents, strong de-greasers, alcohol, lemon or wine. These measures will help you to
keep your loudspeakers' working perfectly for years to come. Time will help improve the sound by
breaking in the speakers' moving parts (membranes and suspensions), and the acoustic chamber
will become accustomed to music being played the more it is used - much like what happens with
acoustic string instruments!
