GENERAL DESCRIPTION
This 2” throat entry horn has been designed in order 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 simplified. To ensure freedom of resonance, this flare is
constructed of high-density rigid polyurethane foam, with flat front finish to facilitate flush mounting, and an aluminium
adapter for precise pattern control.
