Gran Gioia 2x10"

Coax Bass Horn

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.

In our workshop we can offer true-wood veneers.
Wood is a natural product and depending on several factors might have different color and structure. Color and structure variations of the surface are not to be considered flaws.
