PETP-Film diaphragm compression driver
- Sophisticated computer modeling was used to optimize the magnetic and acoustic design ofthese 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 polyamide-insulated, copper-clad aluminum voice coil is edge-wound on a glass fiber former resulting in 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 low distortion performance while improving the lower mid-band response.
