Constant Directivity Horn
KEY FEATURES
•   Designed for compression drivers with 1.4’’
throat diameter
•   It provides uniform response, on and off-axis
with a neutral and natural frequency reproduction
•   Coverage angles of 80? in the horizontal plane
and 50? in the vertical plane
•   Precise directivity control in the pass band
•   Its square form provides more versatility to mount
it in the box
GENERAL DESCRIPTION
This 1.4” entry horn is designed to provide uniform on and off-axis response. The constant directivity characteristics of this model
ensure the ability to cover 80? wide horizontally and 50? wide vertically, at virtually any frequency within its operational range. To
ensure freedom of resonance, this flare is constructed of cast aluminium, with flat front finish to facilitate flush mounting.

Notes:                                    ** Horizontal response is represented by the heavy line. Vertical response is represented by the discontinuous line.
*Horizontal beamwidth is represented by the heavy line.  The  polar plots are reproduction of measurements done with single sinusoidal signal tones, at the indicated frequencies.
Vertical beamwidth is represented by the discontinuous line.  The microphone was placed 2m. from the horn, and rotation was about the centre of the emitter source.
