Architectural and engineering specifications:
The loudspeaker shall be a surface mount, dual-driver
system. The loudspeaker shall consist of two 10" (254
mm) woofers, with a weather resistant poly propylene
cone, and a 2" (51 mm) voice-coil.
The loudspeaker system shall meet the following
performance criteria: Power handling, 400 W of IEC
60268-5 continuous pink noise (6 dB crest factor);
Frequency response, 33 Hz -500 Hz (-10 dB from rated
sensitivity); Sensitivity, 94 dB at one watt, 50 Hz - 150
Hz at one meter; Impedance, two 8 Ohm nominal in
stereo mode, or one 4 Ohm nominal in mono mode.
The finish shall be paintable black (RAL 9004) or
paintable white (RAL 9003). The grille shall be zinc
plated, and powder coated for corrosion resistance.
The loudspeaker shall be designed for floor
installations and shall allow for it to be flown using
