HOW TO USE
The correct choice of the amplifier, its settings and enclosure design prolongs the lifetime of your
subwoofer. You should select an amplifier with a nominal power below the nominal power of the subwoofer.
Proper coordination of the head unit (HU) with the amplifier will provide a clean, undistorted signal fed to
the subwoofer, which prevents overheating and voice coil damage. Like any other speaker the subwoofer
has moving and stationary parts. We strongly recommend that the moving parts of the subwoofer should
be warmed up at the beginning of operation. Be extra careful when warming up the parts. Warm up the
subwoofer using musical material for 40 hours at medium power. If, during operation at maximum volume
you feel strange smell, you should lower the volume of the subwoofer and let the device to cool down at a
low volume.
Recommended settings of the amplifier and HU: Volume of HU should not exceed 80%. The amplifier
sensitivity should be set to 50%, subsonic filter frequency (Subsonic) should be set to 5 Hz below the
port settings. For example, if you configure the port at 30 Hz, Subsonic should be set to 25 Hz. The low
pass filter LPF (the filter that cuts all frequencies above those set for the filter) should be set to 63-80 Hz,
bassboost should be set to 0.
