TD-194
CONSTANT DIRECTIVITY HORN
KEY FEATURES
•   Designed to be used with 1 inch compression drivers
•   Coverage angles of 90? in the horizontal plane and
40? in  the vertical plane
•   Precise directivity control in the pass band
•   Square and compact design, providing versatile mounting
options.
•   Cast aluminium construction
GENERAL DESCRIPTION
This horn has been designed to work  especifically  with 1 inch compression drivers, providing  uniform on and off-axis response.
The constant directivity characteristics of  this model  ensure  the ability to cover 90?  width horizontally and 40? width vertically,
at  virtually any frequency within its operational range. To ensure freedom of resonance, this horn is constructed of cast
aluminium, with flat front finish to facilitate flush mounting. Its square shape allows to easily rotate the horn without any need for
modification in the cabinet.
