GENERAL DESCRIPTION
This low-mid frequency transducer offers three main points of interest: a high efficiency (6 %), 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 15 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=75 l, fb=70 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.

Voice coil: edgewound aluminium wire with high
temperature bonding strength. Polyimide fiber glass
former able to withstand high temperatures.
Cone: light and stiff paper cone to provide good midfrequency response.
Surround: treated cloth to equalize mechanically
the frequency response.
Spider: cotton spider.
Metal parts: anti-corrosion coated back plate
designed to resist aggressive environmental
conditions.
Basket: specially designed die cast aluminium basket to avoid disturbing resonances.
Magnet: high Curie temperature ferrite.
Notes:
* The power capacity is determined according to AES2-1984 (r2003)
standard. Program power is defined as the transducer's ability to handle
normal music program material.
** T-S parameters are measured after an exercise period using a
preconditioning power test. The measurements are carried out with a
velocity-current laser transducer and will reflect the long term parameters
(once the loudspeaker has been working for a short period of time).
