Electro-voice HPS64 DATASHEET

General Product Description

The Electro-Voice® model HP64 is a wide-range,
flat-front, high-frequency, constant-directivity horn.
Furthermore, excellent loading is maintained to a low
frequency of 1200 Hz.

The flat-front design makes the HPS64 suitable for all
modern boxed and clustered systems. A special vaned
waveguide throat detail gives the HPS64 unusually
good high-frequency control, vertically, when compared
to similar 1.4-inch-throat horn designs.

Architects’ and Engineers’ Specifications

The horn shall be of the constant-directivity type. It shall
produce a horizontal nominal beamwidth (6 dB-down
angle) of 60 degrees. It shall produce a vertical nominal
beamwidth of 40 degrees. it shall provide useful
acoustic loading at all frequencies above 1200 Hz.

The horn shall be of hybrid fiberglass-and-zinc
construction. The driver-mounting flange and initial
throat section shall be constructed of die-cast zinc and
shall be integrally laminated into the fiberglass portion
of the horn.
