Commentary
Flat front biradial horn developed as a small and lightweight type.
The 2370A has a throat diameter of 25 mm and a coverage angle of 90 ° x40 °.
The vertical directivity gradually narrows as the frequency increases, which helps to keep the horizontal characteristics constant and to correct the driver characteristics.
It can be flash-mounted in a speaker cabinet or used for compact cluster configurations.
The directional control in the horizontal plane is designed with precision to prevent narrowing in the mid-range and beaming in the high-range.
Furthermore, by stacking multiple horns, it is possible to control the orientation of a vertical plane comparable to that of a large horn.
Because the overlap of the horns is minimal, you can eliminate the effects of roping and comb filters.
