DFX-20 Subwoofer box

The 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. The housing is made of 15 mm birch plywood and coated with a very robust textured paint. The front grille is made of powder coated steel. 4 casters and 4 ergonomic handles provide simple handling.
