Running-in period

The drivers used in the loudspeaker are complex mechanical devices and require a run-in period before they deliver their
best performance. They must get adapted to the temperature and humidity conditions of their environment. This breaking-in
period depends on the encountered conditions and can last several weeks. In order to shorten this period, we advise you
to let your loudspeakers operate for about twenty hours at medium level, playing standard musical programmes, but with
a large amount of bass.
Once the components of the loudspeakers are completely stabilized, it is possible to enjoy the real performance of your
loudspeakers.

Specifications

energy transfer. Aluminum / Magnesium dome with Poron surround reveals outstanding performance thanks to a more
®
dynamic and softer tweeter.

proportioning of glass leaf, new foam thickness.
