This low-mid frequency transducer offers three main points of interest: a high efficiency (5.1 %), an extremely linear frequency response and a low harmonic distortion. These characteristics make it 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 transducer 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 12 MI100 reaches a considerable power handling (450 WAES).

Key features:
  • Very high efficiency (5.1 %)
  • Extremely linear frequency response
  • Low harmonic distortion
  • 3 edgewound aluminium voice coil with polyimide fiber glass former
  • Large magnetic assembly to provide efficient heat dissipation
  • Designed for high quality mid-frequency reproduction
