CD-171Fe/PT – Compression driver
This next-generation high-performance 1” (25.4 mm) exit compression driver delivers exceptional efficiency and power handling for professional audio applications. Featuring Deplocex® patent-pending technology, it offers improved thermal dissipation, reduced power compression losses, and reliable high-power performance. The driver is equipped with a 1.75” (44.4 mm) copper-clad aluminium voice coil on a Kapton former, capable of handling 160 W program power above 1.4 kHz, and provides a high sensitivity of 109 dB (1 W / 1 m). Its exclusive high-temperature polymer dome and surround are FEM-optimized for a linear, extended frequency response with minimized resonances, while a copper shorting cap reduces distortion and ensures linear inductance. The FEM-optimized ceramic magnetic circuit and robust aluminium cover complete a design focused on durability, clarity, and consistent high output.
