10 Watt 4-Inch Full-Range Ceiling Loudspeaker with 8-Watt, 70.7 Volt Transformer


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.

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.

The 209-4T includes a transformer, allowing 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.
