Supertweeter Horn
General Product Description
®
The Electro-Voice model HPT94 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 HPT94 suitable for all modern boxed and clustered
systems.
