Commentary
Horn type tweeter provided with an elliptical opening.
Phase characteristics and amplitude-frequency characteristics are exactly flattened by the combination of an elliptic aperture exponential horn and phasing plug.
The phase relationship with the woofer is considered to be equal when the baffle is mounted.
