The Sound Chisel multiplies the sonic cone of the high- and midrange speaker of normal hi-fi speakers.

The result is a better auditory impression in a larger area of the room.

The big advantage to 360-degree-speakers is the much lesser scattering of the sound. So normal amplifiers are suited for the Sound Chisel too.
