Pon-Tunes are like no other vibration device. Most vibration control devices are variations of the same theme of spikes,cones,mats, and pads.
They all have basically affect the sounding same limited and often negative ways, such as when multiple materials layers lead to phase and temporal incoherence issues. The importance of the chassis to move slightly in response to impinging sound waves or floor born vibrations rather the absorb the wave into its interior. Rolling feet enable the chassis to move ever so slightly in response to sound waves or in response to vibrations coming up through the equipment rack.
True emotional involvement with the music comes mainly from temporal information. It was the benefits gained in this area that prompted the final product.
