The Horn Loudspeakers Blumenhofer Acoustics Gran Gioia 2x10"
Working on a new horn concept to have a smaller full horn loudspeaker, it developed to become a proficient loudspeaker in a certain kind of coaxial configuration: the two woofers working in the same horn mutate to one only loudspeaker. Therefore it is a Coax a 'la Blumenhofer' with a compression driver horn in the middle.
