General Description:
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 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
either 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
enamel. 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 dispersion, high-efficiency, high-maximum output, ease of
installation, and wide-range reproduction of music or voice.
