Break-in period
The speaker drivers used in Sopra loudspeakers are complex mechanical components which require a certain
time to adapt to operate at their best and to become acclimatised to the temperature and humidity of the listening
environment. This break-in period varies depending on the climate and may last a few weeks. To reduce the
break-in period, we recommend operating the loudspeakers for approximately twenty consecutive hours. Once the
loudspeakers' characteristics have totally stabilised, you will be able to enjoy your Sopra loudspeakers' performance
to the full.
Special precautions
The only maintenance required for the Sopra loudspeakers is dusting with a dry cloth. If your loudspeaker becomes
dirty, we recommend simply cleaning it with a damp cloth.
Never use solvents, detergents, alcohol-based or corrosive products, scrapers or scourers to clean the surface of
a loudspeaker.
Keep the loudspeakers away from sources of heat.
Choosing the right amplifier
It is not an excess of amplifier power that can damage your loudspeakers and speaker drivers but a lack of power.
Moreover, if the volume is turned up too high, the amplifier saturates and generates parasite signals that may
damage the tweeter. The dynamic capacity and definition of Sopra loudspeakers are sufficient to reveal the strengths
and weaknesses of whatever amplifier is connected. Your retailer will be able to help you choose the amplifier best
suited to your tastes and budget.
