The low-mid frequency Beyma 12MI100 driver offers very high efficiency of 5.1%, an extremely linear frequency response and a low harmonic distortion. These characteristics make Beyma 12MI100 suitable for high quality sound reinforcement systems, especially for live applications. Moreover, its versatile design allows it to be used as the low-mid loudspeaker in a two ways system or as an strictly mid-frequency driver in a three ways system. Beyond its frequency response advantages, this loudspeaker offers more: it takes profit of the improvements achieved in our low frequency-high power transducers. Thus, it incorporates a high quality voice coil and a large magnetic assembly to provide efficient heat dissipation. Thanks to this design concept of strongness, the 12MI100 reaches a considerable power handling (450W AES).
