ARCHITECTS AND ENGINEER SPECIFICATIONS
The speaker shall be 4'%" square and shall have a sensitivity of 92 dB (SPL at 4 ft.
from 1 Watt) measured on axis. The loudspeaker shall have a nominal impedance of
8 Ohms and a pov/er rating of not less than 10 Watts with the frequency response
uniform over the range of 60 to 15,000 Hz. Free air resonance shall not be higher
than 70 Hz.
The voice coil shall have a diameter of 1" and shall operate in a magnetic field of at
least 10,250 gauss derived from a magnet of Indox V having a weight of 1% lbs. The
speaker terminals shall be of the solder lug type. The speaker shall weight 2% lbs. and
shall be able to perform efficiently in a volume as low as 0.1 cubic feet. It shall have a
solid, welded construction and water resistant cone (to prevent distortion in high humidity
areas).
Any loudspeaker not meeting these requirements shall not be acceptable under this
specification.
The loudspeaker shall be Altec Lansing Model 405A.
