209 Series
8 inch Full-Range
Ceiling Loudspeakers
COMMERCIAL
General Product Description
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.
Architects’ and Engineers’ Specifications
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
lb). 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.
