Beyma CD1S - 1" 8ohm 106dB 30W Ferrite compression driver

Featuring a 1 3/8 inch screw-in design and fitted with a ferrite magnet and lightweight voice-coil, the Beyma CD1S compression driver delivers professional treble performance. This driver boasts a 2,000 to 20,000 Hertz frequency range, which couples with a polymer diaphragm and 106 decibel sensitivity level to result in efficient acoustic power supported by a flat response and low harmonic distortion. Once installed, the CD1S guarantees an AES power output of 30 Watts at 8 Ohms.
