HOW TO USE

The correct choice of the amplifier settings prolongs the lifetime of your subwoofer. Proper coordination of the head unit (HU) with the amplifier will provide 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 you feel strange smell during operation at maximum volume, 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%. The low pass filter LPF (the filter that cuts all frequencies above those set for the filter) should be set to 63-80 Hz.
