PETP-FILM DIAPHRAGM COMPRESSION DRIVER
Sophisticated computer modeling was used to optimize the magnetic and acoustic
design of these ferrite magnet compression drivers to achieve outstanding
performance and reliability.
A matched wave front phase corrector produces a perfectly coherent sound wave
at the horn throat, for a detailed and dynamic mid and high frequency
performance.
The polyimide-insulated, copper-clad aluminum voice coil is edge-wound on a
glass fiber former resulting in a lower distortion and superior power to weight
ratio.
A one-piece, PETP film diaphragm and surround optimizes energy transfer for
greater efficiency
The unique patented clamping system contributes directly to a low distortion
performance while improving the lower mid-band response.
