FC100
Compound
Diffraction Horn
General Product Description
The Electro-Voice FC100 consists of two horn sections for
use with 1828C or 1829 model drivers to form a wide-range,
integrated system.
The folded construction of the rear horn coupled with the
smaller dimensions of the front horn, present a 1,000 Hz
acoustic crossover. This separation of frequencies provides
a more extended frequency response and cleaner sound.
The 150 degree horizontal by 110 degree vertical dispersion
pattern is beneficial in many applications requiring a wide
coverage pattern. Fur thermore, excellent loading is
maintained to a low-frequency cutoff of 260 Hz.
Architects’ and Engineers’ Specifications
The horn shall be the compound diffraction type with outer
housing of fiberglass, a zinc diecast front horn and phenolic-
constructed inner horns.
The low-frequency horn will be 52.0 cm (20.5 in.) high by
26.5 cm (10.5 in.) wide and 51.0 cm (20.0 in.) deep, not
including a driver. Net weight (less driver) shall not exceed
4.9 kg (10.8 lb).
A separate high-frequency horn shall be provided, capable
of individual rotation. The acoustical crossover shall be 1,000
Hz.
