Model Summary
EVID™ FM4.2
The Electro-Voice® EVID FM4.2 flush-mounted loudspeaker system is a
complete two-way in-wall loudspeaker package. The package consists 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 EVID FM4.2 utilizes a transformer that offers a selection of 1.75,
3.75, 7.5, 15 or 30 watts delivered to the loudspeaker system using ei
-
ther 70-V or 100-V lines. The wattage is selected via a convenient switch
on the front baffle. The unit can also be operated as an 8-ohm speaker
via the same front panel selector switch.
The perforated grille is finished in semi-gloss white powder-coated enam
-
el. The baffle and bezel is constructed from heat resistant ABS. 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 disper-
sion, high-efficiency, high-maximum output, ease of installation, and
wide-range reproduction of music or voice.
