HPT94
Constant-Directivity
Supertweeter Horn
General Product Description
The Electro-Voice
®
model HPT94 is a wide-range, flat-
front, constant-directivity super-tweeter horn. Both
horizontal and ver tical angles are controlled from 3 kHz
to 20 kHz with unusual precision and adherence to the
intended angle. Fur ther more, excellent loading is
maintained to 1,600 Hz. The flat-front design makes
the HPT94 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
90 degrees, deviating no more than 15 degrees from
this angle over the frequency range 3 kHz to 20 kHz. It
shall produce a ver tical beamwidth of 40 degrees,
deviating no more than 20 degrees from this angle over
the frequency range 4 kHz to 20 kHz. In addition, it
shall provide useful acoustic loading at all frequencies
above 1.6 kHz.
The hor n shall be of hybr id fiberglass-and-zinc
c o n s t r u c t i o n . T h e i n i t i a l t h r o a t s e c t i o n s h a l l b e
constructed of die-cast zinc and shall be integrally
laminated into the fiberglass por tion of the horn.
Specifications:
The following specifications are in accordance with or

The horn shall possess a throat of 2.36 cm (0.93 in.)
diameter and shall be provided with a 1-3/8"-18
threaded hole for mounting of a compression driver.
The horn shall be 13.3 cm (5.3 in.) high, 13.3 cm (5.3
in.) wide, and 10.1 cm (4.0 in.) long. It shall weigh no
more than 1.8 kg (4.0 lb).
The horn shall be the Electro-Voice model HPT94
constant-directivity horn.
Construction:
Polyester resin and glass-fiber laminate integrally
molded to a die-cast zinc throat section. This hybrid
construction assures a rigid driver mount, accurate,
loss-free throat-wave transmission and low total weight
compared to horns of similar size.
Mechanical Connection of Driver:
1-3/8"-18 threaded hole
Recommended Driver:
DH2010A, DH2T
Weight:
1.8 kg (4.0 lb)
