The MADRAS M18 is an active, optimally vented subwoofer with integrated controller and Electro-Voice EVX180B woofer.The integrated controller with 124 Hz, 24dB/octave and Linkwitz-Riley characteristics and the electronically balanced XLRF-type connectors allow easy installing an active 3-way system configuration using active top-parts like for example the MADRAS M18 (in mid-high position). Frequency and phase responses of the MADRAS M18 also provide the possibility for direct parallel operation with suitable full-range cabinets. Achieving this is possible by simply feeding the MADRAS M18 Sub with a line level audio signal from a separate mixer output. Balance between MADRAS M18 Sub and top-parts can be established from the mixing console.An 800W high-efficiency class-H power amplifier provides ample power. Consequential use of class-H technology reduces power dissipation, power consumption as well as the power amp�s weight noticeably. The power amplifier is convection-cooled, resulting in no disturbing noise from running fans.
