The Electro-Voice model HP64 is a wide-range, flat-front, high-frequency, constant-directivity horn. It offers economy of space, where geometry is “just big enough for the job.” A horizontal angle is controlled over a frequency range of 1.7 kHz to 20 kHz and the vertical angle is controlled from 1.8 kHz to 20 kHz, both with unusual precision and adherence to the intended angle. Furthermore, excellent loading is maintained to a low frequency of 650 Hz. The HP horn series (U.S. Patent #4,629,029) represents the latest development in “CD” horn design, employing the same principles which EV engineers developed and used to design the world’s first constant directivity horns in 1974. The flat-front TransPlanar™ design makes the HP64 suitable for all modern boxes and clustered systems. A unique, integral fiberglass-and-zinc construction gives a strength-to-weight ratio superior to that of conventional fiberglass horn construction, resulting in exceptional strength in the throat area and elimination of acoustically induced wall vibrations. Lastly, a special vaned waveguide throat detail gives the HP64 unusually good high-frequency control vertically, when compared to similar 2-inch throat horn designs.

The Electro-Voice model HP94 is a wide-range, flat-front, high-frequency, constant-directivity horn. It offers economy of space, where geometry is “just big enough for the job.” A horizontal angle is controlled over a frequency range of 1.2 kHz to 20 kHz and the vertical angle is controlled from 2.1 kHz to 20 kHz, both with unusual precision and adherence to the intended angle. Furthermore, excellent loading is maintained to a low frequency of 800 Hz.
