EXP 8/27/97 SHB
The dedicated mid frequency module shall incorporate 3x
horn-loaded 10-in MF transducers. The module shall have a
nominal horizontal coverage pattern of 30°. The module’s ver-
tical beam profile shall be adjustable via complex digital sig-
nal processing. The module shall be integrated with comple-
mentary frequency-specific modules into a single acoustical
unit via complex digital signal processing.
The module shall be equipped with a switch to control an
internal passive filter network providing processing appropri-
ate to the modules use in an inner or outer array column.
Module frequency response shall vary no more than ±3 dB
from 100 Hz to 1.27 kHz measured on axis. The module shall
produce a Sound Pressure Level (SPL) of 112 dB SPL on axis
at 1 meter with a power input of 1 Watt, and shall be capa-
ble of producing a peak output of 148 dB SPL on axis at 1
meter. Each driver shall handle 400 Watts of amplifier power
(AES Standard) and shall have a nominal impedance of 8
Ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 1/2-in thickness void-free cross-grain-
laminated Baltic birch plywood and shall employ extensive
internal bracing. It shall be finished in black catalyzed
polyurethane. Input connectors shall be one each male and
female AP6. The enclosure shall include sixteen 3/8”-16
threaded mounting/suspension points (4 each top, bottom
and sides). The front of the loudspeaker shall be covered with
a vinyl coated perforated steel grille backed with open cell
foam to protect against dust.
The long throw/downfill mid frequency module shall be the
EAW model KF920.
