Electro-Voice Evid FM 4.2 - Pasivna 100V zvučna kutija

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 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.
