Moteur à Compression Beyma SMC-280ST
[SMC280ST-8] Avis/Critiques

This 1" compression driver features a lightweight mylar diaphragm that provides an excellent high frequency response with low harmonic distortion. Other key features of this model are its excellent sensitivity (105 dB) and its high power handling (50 w AES above 1.5 kHz). By the other hand, the coil-diaphragm assembly is easily field without soldering.
