General Product Description

The Electro-Voice®model HPT64 is a wide-range, flat- front, constant-directivity super-tweeter horn. Both horizontal and vertical angles are controlled from 3 kHz to 20 kHz with unusual precision and adherence to the intended angle. Furthermore, excellent loading is maintained to 1,600 Hz. The flat-front design makes the HPT64 suitable for all modern boxed and clustered systems.

Architects’ and Engineers’ Specifications

The horn shall be of the constant-directivity type. It shall produce a horizontal beamwidth (6-dB-down angle) of 60 degrees, deviating no more than 20 degrees from this angle over the frequency range 3 kHz to 20 kHz. It shall produce a vertical beamwidth of 40 degrees, deviating no more than 20 degrees from this angle over the frequency range 3 kHz to 20 kHz. In addition, it shall provide useful acoustic loading at all frequencies above 1.6 kHz.

The horn shall be of hybrid fiberglass-and-zinc construction. The initial throat section shall be constructed of die-cast zinc and shall be integrally
