Care and cleaning tips
Caution!
Improper handling of the speaker may result in damage.
• Always unplug the speaker before cleaning it!
• Before recommissioning, make sure that all connections are cor-
rect, that there are no short circuits and that the speaker is com-
pletely dry.
• Never use strong cleaning agents or solvents such as petrol, spir-
it or similar!
Enclosure
We recommend commercial window cleaner sprayed onto a cotton
cloth. This allows almost all fingerprints and dust to be easily re-
moved. Alternatively, you can also use window active foam.
We advise against the use of microfibre cloths! These can cause
mini scratches in the surface.
Diaphragms and Speaker Chassis
To remove dust from a loudspeaker chassis, a lint-free cotton cloth
is sufficient to wipe the membrane lightly with very little pressure.
The tweeters of all Nubert loudspeakers are equipped with a pro-
tective grille so that they can also be wiped off with low pressure. If
the dust cannot be completely removed, a make-up brush from the
drugstore is suitable.
