KEY FEATURES
•   High power handling (250 w AES)
•   Low harmonic distortion
•   Controlled dispersion up to 3 kHz
•   2” edgewound aluminium voice coil with
polyimide fiber glass former
•   Designed for high quality mid-frequency
reproduction
GENERAL DESCRIPTION
This low-mid frequency transducer offers three main points of interest: a good sensitivity  (98 dB), a controlled dispersion up to
3 kHz and a low harmonic distortion. These characteristics make it suitable for high quality sound reinforcement systems,
especially for live applications. Furthermore, it is mounted with a cast aluminium basket that reduces mechanical vibrations and
increases thermal dissipation. This fact, added to the use of a high quality 2’’ voice-coil, increases considerably the power
handling reaching 250 w AES.

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
