The HP horn series is a refinement of the concept of “con-
stant directivity,” which, in 1974, EV was the first to intro-
duce. For the first time, horn coverage angles were truly
uniform over a wide frequency range. In the HP series,
unique beamwidth-control vanes within the horn throat
form a waveguide that eliminates the narrowing of cover-
age angle – beaming – that occurs in other 2-inch-throat

horns. EV’s patented Transplanar™ design provides excep-
tionally smooth frequency response. HP horns or variants
thereof are used throughout the EV speaker system lines.
Each HP horn features an integral die-cast metal throat
encapsulated in the fiberglass sidewalls. This unitized con-
struction provides very high strength and low weight.

• Large-format two-inch horns
• The ultimate in dispersion

control, with control of rated
dispersion angle down to
500 Hz, both horizontally and
vertically

• Directivity control to 500 Hz

maximizes vocal intelligibility
and musical clarity in difficult
acoustic environments

HP420

HP1240

• Medium-format two-inch horns
• Vertical dimensions have been

reduced, for use when space
constraints preclude the use
of large-format horns

• Horizontal directional control

maintained to ~500 Hz

• Vertical control to ~1,500 Hz

HP64
HP66
HP94

• Small-format two-inch horns
• Use as primary HF horns in

compact sound systems

• Beamwidth control to ~2,000 Hz

HPT64
HPT94

• Very-small-format one-inch

horns

• Use in three- and four-way

systems with DH3 driver for
tweeter and supertweeter
applications

• Directional control to 3,000 Hz
