The Dynacord FX20-PRO is a horn-loaded subwoofer with an Electro-Voice EVX180B 18“ high performance transducer. Nominal impedance is 8 Ohm, power handling 600 W RMS. Power amps up to 1200 W/ 8 Ohm can be used in order to have maximum dynamic range without the danger of thermal overload in noncontrolled situations. The sensitivity of the cabinet is 101 dB/1 W/1 m, the maximum SPL is 135 dB. The driver is protected by a “Voice Coil Tracking” system called protection circuitry which prevents overheating. Recommended crossover frequencies are 80 to 140 Hz depending on the application.
