Product Description
The DS 16F loudspeaker is a 16-watt, ported loudspeaker system utilizing one 2.25" (57mm)
full-range driver. The loudspeaker is designed for installation in ceilings up to 20ft (6.1m) high. An
optional pendant-mount accessory allows the loudspeaker to be hung from open ceilings.
The loudspeaker has a nominal ratedimpedance of 8 ohms and is wired in parallel with a line
voltage matching (step-down) transformer with a selector switch appropriate for various output
taps. The loudspeaker input connections allow for direct connection to either 70V, 100V or low-
impedance amplifiers.
Exposed cosmetic surfaces of the loudspeaker are paintable, and the acoustically transparent
grille component is formed of powder-coated steel.
Each loudspeaker has a bandwidth of 90 Hz – 16 kHz and a maximum continuous acoustic
output of 96 dB-SPL, referenced to a full bandwidth pink noise input at 1 meter at the
loudspeaker’s rated power.
The input connection consists of a three-position barrier connector with a pre-wired ceramic
connector. The loudspeaker meets numerous standards for combination music and evacuation
systems around the world.
Power settings available are: 1W, 2W, 4W, 8W, 16W @ 70V; 2W, 4W, 8W, 16W @ 100V; and
16W @ 8½ (when referenced to IEC noisefor 100 hours). The nominal dispersion is 140°conical
coverage pattern at -6 dB (average 1 – 4 kHz).
