The correct choice of the ampliﬁer, its settings and design prolong 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 on medium power. If, during operation at maximum volume you feel strange

smell, you should make the volume of the subwoofer low and cool the device down at a low volume.

Recommended settings of the ampliﬁer and HU: Volume of HU should not exceed 80%. The ampliﬁer sensitivity is 50%,

subsonic ﬁlter frequency (Subsonic) is 5 Hz below the port settings. For example, if you conﬁgure the port at 30 Hz, Subsonic is

should be 25 Hz. The low pass ﬁlter LPF (the ﬁlter that cuts all frequencies above those set for the ﬁlter) 63-80 Hz, bassboost to 0.
