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.
