GENERAL DESCRIPTION
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
(350 WAES).
FREQUENCY RESPONSE AND DISTORTION CURVES                            FREE AIR IMPEDANCE CURVE
Note: on axis frequency response measured with loudspeaker standing
on infinite baffle in anechoic chamber, 1w @ 1m.
PREDICTED LOW FREQUENCY RESPONSE                              POWER COMPRESSION LOSSES
Note: Bass-reflex cabinet, Vb=30 l, fb=94 Hz  Note: These losses are calculated from a five minutes AES power test
applying band limited pink noise (120-3500 Hz). The loudspeaker is free-air
standing.
