TD250
Constant Directivity Horn
KEY FEATURES
? Designed for compression drivers with 1"
mouth diameter
? It provides uniform response, on and off-
axis with a neutral and natural frequency
reproduction
? Coverage angles of 90? in the horizontal
plane and 40? in the vertical plane
? Straightforward mounting thanks to its plane
mouth finish
GENERAL DESCRIPTION
This 1” throat entry horn has been designed to provide uniform on and off-axis frequency response, with uncoloured
and natural sound reproduction. The constant directivity characteristics of this model ensure the ability to cover 90°
wide horizontally and 40° wide vertically, at virtually any frequency within its operational range. Since the response
remains essentially constant, equalisation is easily simplifed. To ensure freedom of resonance, this flare is constructed
of high-density rigid polyurethane foam, with flat front finish to facilitate flush mounting.
