PETP-FILM DIAPHRAGM COMPRESSION DRIVER
(ACTPRO-1515 HD)
• Optimized acoustic and magnetic design achieves outstanding
clarity and reliability
• A one-piece, PETP film diaphragm and surround optimizes
energy transfer for greater efficiency
• Patented clamping system yields low distortion performance
while improving the mid-band response
• Polyimide-insulated, copper-clad aluminium voice coil is
edgewound on a glass-fiber former producing lower distortion
and superior power-to-weight ratio
• A matched wave front phase corrector produces a coherent
sound wave at the horn throat, yielding detailed and dynamic
mid and high frequency response
