The Beyma CD151FE/PK is a compact, high-performance compression driver featuring a 1″ (25.4 mm) throat and a 1.5″ (38.1 mm) voice coil. Built with an advanced Polyimide diaphragm, it offers excellent high-frequency reproduction, extended bandwidth up to 20 kHz, and improved durability under high power conditions compared to polyester-based diaphragms. With Deplocex® and VPEQ® technologies, the driver provides enhanced thermal management, reduced distortion, and a more linear response. Offering a sensitivity of 110 dB (2–7 kHz on TD-164 horn) and program power handling of 140 W, the CD151FE/PK is ideal for two-way and multi-way professional loudspeaker systems.
