walls and tight ceiling spaces.
Titanium coated tweeter gives even uniform high frequency coverage
Full bandwidth overload protection
Front baffle wattage tap adjustment allows for easy level
matching after installation.

General Description:
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” lowfrequency 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.

The EVID FM4.2 loudspeaker system shall be comprised of a
baffle/bezel assembly, front grille, rear enclosure, transformer, 4”
passive radiator, and 4” loudspeaker. The loudspeaker will feature
an 4” low-frequency cone and a high-temperature voice-coil assembly, coupled with a 4-inch passive radiator. A 1” wide dispersion titanium coated dome tweeter extends the response to 20
kHz. Frequency response, uniform from 85 Hz to 18 kHz. Pressure
sensitivity, 87 dB SPL at 1 meter (85 dB at 4 feet) on axis with
one watt of band-limited pink noise from 500 Hz to 3 kHz (ref.
20µPa). Minimum impedance, 8.2 ohms. The loudspeaker shall
be 349.9 mm (13.77 in.) by 188.3 mm (7.42 in.) and 96.5 mm (3.80
in.) deep. Weight shall be 2.9 kg (6.5 lb) each. The flush-mounted
loudspeaker package shall be the Electro-Voice model FM4.2.
