Product Overview

Beyma 10MI100 , MI100 Series

This low-mid frequency transducer offers three main points of interest: a high efficiency (5.2 %), an extremely linear frequenc y response and a low harmonic distortion. These characteristics make it suitable for high quality sound reinforcement systems, especially for live applications. 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 10 MI100 reaches a considerable power handling (350 W AES ).
