Sonus Faber

The Sonus Faber Gravis III subwoofer is made according to the classical scheme in a closed rectangular (almost cubic) case with a 10-inch driver on the side wall. This ultra-long-range speaker, with which the Gravis III showed a lower limit of 25 Hz, received a three-layer sandwich diffuser reinforced with a spatial honeycomb structure.

This model is equipped with a low-frequency driver with a diameter of 8 inches with a very large amplitude of the diffuser movement. The bass unit is located on the bottom panel of the subwoofer and is aimed at the floor, which ensures an even distribution of bass in the listening room.

The subwoofer is equipped with a 10-inch woofer with a diffuser made of impregnated paper. The diffuser is mounted on a wide rubber suspension, which ensures its rapid movement with a large amplitude. The bass is loaded onto a passive radiator. The radiator on the front panel of the subwoofer is covered with a removable safety net.
