Architects’ and Engineers’
Specifications
The loudspeaker will be a 16 watt, ported loudspeaker system
utilizing one 2.25" (57 mm) full-range driver. The loudspeaker
shall be designed for installation in ceilings up to 20 ft (6.1
m) high. An optional pendant-mount accessory allows the
loudspeaker to be hung from open ceilings.
The loudspeaker shall have a nominal rated impedance of 8 ohms
and shall be wired in parallel with a line voltage matching (stepdown) transformer with a selector switch appropriate for various
output taps. The loudspeaker input connections will allow for
direct connection to 70 volt, 100 volt or low-impedance amplifiers.
Exposed cosmetic surfaces of the loudspeaker shall be paintable,
and the acoustically transparent grille component shall be formed
of powder-coated steel.
Each loudspeaker shall have a bandwidth of 95 Hz – 17 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 shall consist of a
three-terminal barrier strip. The loudspeaker shall meet numerous
standards for combination music and evacuation systems around
the world.
Power settings available shall be: 1, 2, 4, 8, and 16 watts at
70 volts; 2, 4, 8, and 16 watts at 100 volts; and 16 watts at 8
ohms (when referenced to IEC noise for 100 hours). The nominal
dispersion shall be 140° conical coverage pattern at -6 dB
(average 1 – 4 kHz).
The loudspeaker shall be the Bose® FreeSpace® DS 16F
