M 15

The MADRAS M15 mid/high frequency range is reproduced by an Electro-Voice ND6 neodymium driver with 3” voice-coil while an Electro-Voice EVX155 transmits the bass frequency range. The integrated power amplifier provides discrete low and high range channels, an integrated active frequency crossover (Linkwitz-Riley, 124Hz, 24dB/octave) and signal processing. Selecting “FULL-RANGE” or “MID-HIGH” operation is possible via switch button. A high-efficiency Class-H power amplifier provides the low range signal. Consequential use of Class-H technology reduces power dissipation, power consumption as well as the power amp’s weight noticeably. High range audio signal amplification is realized via a separate power amplifier. Both power amp blocks are convection-cooled, resulting in no disturbing noise from running fans. The power output capacity of 600W (460W + 140W) allows peak sound pressure levels of more than 128dB at lowest distortion rates. The achievable coverage range approximately doubles the scope of conventional passive loudspeaker systems. The wide radiation angle of 80°x 55° eliminates alignment problems inherent to narrow-angled speaker systems.
