The dedicated low frequency module shall incorporate 4x 15in LF transducers. The LF drivers shall be reverse mounted in
horizontal pairs to optimize LF driver coupling. The module’s
horizontal and vertical beam profiles shall be adjustable via
complex digital signal processing. The module shall be integrated with complementary 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 appropriate to the modules use in an inner or outer array column.
Module frequency response shall vary no more than ±3 dB
from 38 Hz to 350 Hz measured on axis . The m od ule shall pr oduce a Sound Pressure Level (SPL) of 101 dB SPL on axis at 1
meter with a power input of 1 Watt, and shall be capable of
producing a peak output of 140 dB SPL on axis at 1 meter.
Each driver pair shall handle 2000 Watts of amplifier power
(AES Standard) and shall have a nominal impedance of 4
Ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 1/2-in thi ckn ess voi d-fr ee cr oss-gr ainlaminated 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 th e loudspeaker shall be covered with
a vinyl coated perforated steel grille backed with open cell
foam to protect against dust.
The dedicated low frequency module shall be the EAW model
KF930.
