Architects' & Engineers' Specifications
The loudspeaker shall be a 100 watt, ported loudspeaker system utilizing one 2.25" (57 mm) mid-high frequency driver and a separate 5.25" (133 mm) woofer. The loudspeaker shall be designed for installation in ceilings up to 32 ft (10 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 (step-down) transformer with a level selector 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 75 Hz – 18 kHz and a maximum continuous acoustic output of 105 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 with a pre-wired ceramic connector. The loudspeaker shall be plenum-rated for use in air handling spaces. The loudspeaker shall meet numerous standards for combination music and evacuation systems around the world.
Power settings available shall be: 12.5, 25, 50, and 100 watts at 70 volts; 25, 50, and 100 watts at 100 volts; and 100 watts at 8 ohms (when referenced to IEC noise for 100 hours). The nominal dispersion shall be 160° conical coverage pattern at -6 dB (average 1 – 4 kHz).
The loudspeaker shall be the Bose® FreeSpace® DS 100F loudspeaker.
