PDFCeiling 209 Spec Sheet (pdf)

The Electro-Voice® 209 is a high-quality 8", 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. To ensure long-term reliability in installations, the 209-8A is designed to handle 10 watts continuous power (40 watts peak) of shaped white noise signal for eight hours per EIA RS-426-A 1980.


  • 8" Full-Range Ceiling Loudspeaker
  • 22-gauge stamped steel frame
  • Available with a 4 watt transformer(209-4T)
  • The 209-4T allows connection to 25/70/100-volt line, with taps of 0.5 to 4 watts
  • The 209-4TWB offers the same performance as the 209-4T and includes a premounted ceiling grille

Architectural and Engineering Specifications

The loudspeaker shall be a dual-cone loudspeaker with a nominal diameter of 20.6 cm (8.1"), an over depth of 7.0 cm (2.75"), and shall weigh no more than 1.0 kg (2.2 lb). The voice coil shall have a nominal diameter of 2.54 cm (1.0") and depth of 7.6 mm (0.3") 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") free-edge cone attached to the apex of the low-frequency device and protected from dust by a dome fastened to the low frequency cone.

The loudspeaker shall exhibit a sensitivity (SPL, 1 watt at 1 meter 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 kHz 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 DC 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.
