The Electro-Voice® EVID FM4.2 flush-mounted loudspeaker system is  
a complete two-way in-wall loudspeaker package. The package con-  
sists of a bezel assembly, grille, rear enclosure, 4” two-way loudspeaker  
coupled with a 4” passive radiator and an internal line-matching  
transformer. The loudspeaker features 4” low-frequency cone and  
high-temperature voice-coil assembly along with a 4” long excursion  
passive radiator and titanium coated dome tweeter. The EVID FM4.2  
loudspeaker utilizes a crossover network, centered at 3,600 Hz, that  
provides 16-dB-per-octave tweeter protection outside of its operating  
range. In addition the EVID FM4.2 features a comprehensive protection  
circuit to shield the woofer and tweeter drivers from excessive power  
levels.

The rear enclosure is constructed from zinc-plated, steel. The rear  
enclosure provides an optimum internal volume, ensuring extended low-  
frequency performance. It is constructed from heavy-gauge, rugged  
steel. The steel rear enclosure was optimized using FEA to virtually  
eliminate panel resonance. The entire enclosure is less than 4” deep  
providing an easy installation into nearly any tight wall or ceiling space.  
A rear cover, with provisions for a junction box fitting, provides access  
to a 4-pin terminal block that allows direct connection to the speaker  
and provides pass through to additional speakers. FM4.2 loudspeakers  
provide wide dispersion, high-efficiency, high-maximum output, ease of  
installation, and wide-range reproduction of music or voice.
