GENERAL DESCRIPTION
This 6"1/2 is an improved version of the former 6 MI80. It is mounted with a cast aluminium basket that reduces
mechanical vibrations and increases thermal dissipation. It has been especially designed for high quality sound
reinforcement systems, mid and mid bass applications.
FREQUENCY RESPONSE AND DISTORTION CURVES                            FREE AIR IMPEDANCE CURVE
Note: on axis frequency response measured with loundspeaker standing
on infinite baffle in anechoic chamber, 1w @ 1m.
FREQUENCY RESPONSE OUT OF AXIS                               POWER COMPRESSION LOSSES
Note: These losses are calculated from a five minutes AES power test
applying band limited pink noise (100-5000 Hz). The loudspeaker is
free-air standing.
