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

unifor

m 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 hor

n features an integral die-cast metal throat

encapsulated in the fiberglass sidewalls. This unitized con-

struction provides very high strength and low weight.

HP9040

• 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

HP640

HP940

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
