Break-in period
Sud 10 and Sub 12 drive units use the very latest components, in the
classic format. To ensure such complex mechanical elements work in
harmony with each other, they must be allowed to function correctly
in this environment. Changes in temperature and humidity are
regarded as very hostile. In order to get the best of your subwoofer,
a running-in period must be respected to ensure they are ready for
this. We recommend that, once the system is ready for listening,
the drive units should be run-in with medium volume setting, with
music that has the full bandwidth of frequencies (sub-bass through
treble). This running-in period should last for a few weeks, to gain
the full potential. After which the excellent performance of your
Subwoofer can be fully appreciated.
