Important recommendations
First of all, check the space available for fitting the speaker drivers (refer to the plans on the packaging) then proceed with the cutting required. If mounted in the factory location, check that there is sufficient space between the speaker driver and the protective grille.

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.
