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.

Recommended Connections
The 209 is a nominal 8-ohm impedance loudspeaker with a
10-watt input capability. However, it is also available with
transformer, the 209-4T, and with transformer and grille, the
209-4TWB.
The 209-4T utilizes a 4-watt, 25/70.7/100-volt universal line
matching transformer with power taps ranging from 0.5 to 4
watts as indicated in the table below. The transformer is
mounted to the frame and the primary winding is accessible
for the user to select any of the power taps indicated in the
table below.
All wattages marked for the various taps refer to the load on
the amplifier, with the insertion loss of the transformer being
less than 2 dB.
Recommended Enclosures and Baffles
209-8A and 209-4T are designed to fit on standard 8-inch
ceiling speaker baffles. Additionally, the 209 series
loudspeakers will accommodate the use of any standard back
enclosure with a diameter of 8.6 inches or greater and a depth
of at least 3.5 inches.
Larger back volumes will increase the lowfrequency output.
The frequency response of a 209 in a typical 0.25-cubic-foot
and 1.8-cubic-foot back enclosure are shownon page 4.
Mounting
The 209 may be front- or rear-mounted against either surface
of its mounting flange and requires a 18.4 cm (7.25 in.)
diameter cutout and a 19.5 cm (7.68 in.) bolt circle. Normal
fasteners up to 5 mm (0.20 in.) will fit through the eight holes
in the frame. The 209 is designed for mounting on standard
ceiling speaker baffles.
