Our unique Patent Pending polycylindrical design will effectively treat the sound waves situated between 600 Hz and 5 kHz . They are fully effective at the close proximity of only a couple of inches , unlike other type of diffusor that need a few feet of distance to be fully effective ( usually 6 feet or more of distance to be fully effective ) .
Our diffusor will also not colour the sound waves , they have no audible sonic signature .
