  • Regular price $41.00


The Electro-Voice 209 is a high-quality 8 inch, full-range loudspeaker for distributed sound systems. An acoustically transparent dome encloses a small, centrally mounted free-edge cone which is used to improve high-frequency dispersion. The 209 is suitable for use in applications requiring highly intelligible speech or smooth musical reproduction. The 209-4TWB offers the same performance as the 209-4T and includes a premounted ceiling grille.The loudspeaker shall be a dual-cone loudspeaker with a nominal diameter of 20.6 cm (8.1 in.), an overall depth of 7.0 cm (2.75 in.), and shall weigh no more than 1.0 kg (2.2 Lbs.). The voice coil shall have a nominal diameter of 2.54 cm (1.0 in.) and depth of 7.6 mm (0.3 in.) and shall operate in a gap of not less than 1.0 T (10,000 Gauss). High frequencies shall be reproduced by 5.7 cm (2.2 in.) free-edge cone attached to the apex of the low-frequency device and protected from dust by a dust dome fastened to the low frequency cone. The loudspeaker shall exhibit a sensitivity (SPL, 1 W at 1 m (3.28 ft) averaged 200 - 4,000 Hz) of no less than 94 dB on axis maintaining an essentially flat frequency response with 3 dB-down points at 115 Hz and 12,000 Hz in a 12-cubic-foot sealed box in a free field. The half-space reference efficiency shall be 1.9%. The nominal impedance shall be 8 ohms and the do resistance shall be 6.5 ohms. The loudspeaker shall be capable of handling a continuous 10-watt (8.6 volts true RMS) shaped white-noise signal (as per EIA RS-426A 1980) with a 6 dB crest factor for eight hours.The loudspeaker shall be the Electro-Voice model 209-8A. When fitted with a transformer that allows connection to 25/70.7/100-volt systems of 0.5 to 4 watts, the loudspeaker shall be referred to as the Electro-Voice model 209-4T and the 209-4TWB with transformer and grille.
