CD-151Fe/PT – Compression driver

The Beyma CD-150Fe/PT is a next-generation, high-performance 1” compression driver designed for superior sound quality and efficiency. It features Deplocex® technology for enhanced thermal dissipation, reduced power compression, and higher power handling, along with a 1.5” copper-clad aluminium voice coil on a Kapton former, delivering up to 140 W program power above 1.8 kHz with 110 dB sensitivity. Incorporating VPEQ® technology and an Advanced Polyester annular ring design optimized via F.E.M. analysis, the driver achieves a linear, extended frequency response with minimized resonances. Additionally, a copper shorting cap ensures low distortion and consistent performance, while the F.E.M.-optimized ceramic magnetic circuit provides precision and reliability for professional audio applications.
