TD245 constant directivity horn
TD245 key features general description 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 60o in the horizontal plane and 40o in the vertical plane straightforward mounting in compact enclosures thanks to its plane mouth finish and minimised horn depth this 1? throat entry horn is constructed of cast aluminium, and is 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 60 wide horizontally and 40 wide vertically, at virtually any frequency within its operational range. since the response remains essentially constant, equalisation is easily simplified. its flat front finish facilitates flush mounting. technical specifications dimension drawings throat diameter 25 mm. 1 in. horizontal beamwidth 60o (+21o -18o) (-6db, 1.25 - 16 khz) vertical beamwidth 40o (+36o -17o) (-6db, 2 - 16 khz) directivity factor (q) 16.6 (average 1.25 -16 khz) directivity index (di) 12.2 db (+2.4 db, -4.1 db) cutoff frequency 1.2 khz dimensions w x h x d: 230 x 170 x 92 mm. cutout dimensions w x h: 180 x 136 mm. net weight 0.8 kg. shipping weight 0.9 kg. construction cast aluminium. connection of driver by three screws on a 57 mm. diameter bolt circle. www.datasheet.co.kr datasheet pdf - http://www..net/
