aintenance of the subwoofer
Although subwoofer systems normally only require very limited maintenance there are several things you can do to
ensure that your Mach system sounds as good 3 years after installation as on the day you bought it:
Never overload your system – stay within the specified limits for power handling.
Always keep the speaker clean and dry.
As with any electrical product, currents will accelerate corrosion of metal surfaces. Therefore, it is recommended to
check the terminals for corrosion at regular intervals, especially if the speaker is mounted in a hostile environment
(high humidity, airborn salt, etc.).
