FX20-PRO
600 W EVX 180B transducer
30–150 Hz (-10 dB)
High-efficiency planar waveguide design
Voice coil tracking protection
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 non-
controlled 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.
