A loudspeaker horn having side wall members which converge to a throat and then diverge at a controlled horizontal dispersion angle allows horizontal dispersion from a bass driver to be maintained up to 4 KHz, permitting higher crossover frequencies and therefore use with lighter and more responsive

A loudspeaker horn having side wall members which converge to a throat and then diverge at a controlled horizontal dispersion angle allows horizontal dispersion from a bass driver to be maintained up to 4 KHz, permitting higher crossover frequencies and therefore use with lighter and more responsive high frequency units.
