Improvements in the acoustic diffusion sound columns, essentially characterized by the fact that the body of the column adopts a hollow revolution cylinder structure, whose bases are covered, with the main loudspeaker providing reproduction of the low frequencies of the audible spectrum in the lower part, immediate to the base, with its axis coinciding with that of the cylindrical box and with its conicity directed towards the base, next to which, on the lateral surface of the box, there is a surrounding annular opening that allows the exit to the outside of the energy produced by the loudspeaker, so that said output is performed circularly and in all directions, completing the acoustic reproduction function with the lateral arrangement of other loudspeakers for the reproduction of the area of the medium and high frequencies of the audible spectrum.
