TD-164 CONSTANT DIRECTIVITY HORN KEY FEATURES • Designed to be used with 1 inch compression drivers • Coverage angles of 60? 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 60? 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. TECHNICAL SPECIFICATIONS Throat diameter 25.4 mm. 1 in. Horizontal beamwidth 60? (+10?,-5?)
