ARCHITECTS & ENGINEERS SPECIFICATION

The loudspeaker system shall be a two-way multi-purpose
type consisting of a 12 inch / 300mm Duplex® loudspeaker
component with a 1.4" exit throat compression driver and
conical horn. The crossover network shall be a dual-
section, 12 dB/octave slope low pass and 12 dB/octave
slope high pass with an electro-acoustic crossover
frequency of 1,500 Hz. The loudspeaker system shall have
an operating bandwidth of 70 Hz - 16 kHz with a
sensitivity of 97 dB when measured at a distance of one
meter. The power handling capability shall be 300 W AES
(1,200 W peak). Nominal impedance shall be 8.0 ohms with
a minimum impedance of 6.1 ohms at 190 Hz. The
loudspeaker shall have nominal coverage angles of 90
degrees in the horizontal plane and 90 degrees in the
vertical plane. The unit shall be a Vented Enclosure,

constructed of 18 mm Poplar plywood painted grey or
white with a cloth covered metal grille. The cabinet shall
include integral suspension points. Forged shoulder
machinery eye bolts shall be included to facilitate the
suspension of the speaker system. The dimensions shall be
22.00 inches high by 18.75 inches wide by 15.00 inches
deep. The loudspeaker system shall weigh 55 pounds (25.0
kg). The loudspeaker system shall be the Altec Lansing
Professional model DX1012-8AG (charcoal grey) or
DX1012-8AW (white).
