ARCHITECTURAL SPECIFICATIONS
The two-way full range loudspeaker systems shall incorpo-
rate a 12-in LF transducer and a 2-in exit compression driver
HF transducer.
The LF driver shall be mounted in a vented enclosure tuned
for optimum low frequency response. The HF driver shall be
loaded on constant directivity horn with a nominal coverage
pattern of 60
°
(h) x 45
°
(v). In passive mode, an internal
passive filter network shall provide fourth order acoustical
crossover and system equalization.
System frequency response shall vary no more than
±
3 dB
from 66 Hz to 18 kHz measured on axis. In passive mode,
the loudspeaker shall produce a Sound Pressure Level (SPL)
of 98 dB SPL on axis at 1 meter with a power input of 1
Watt, and shall be capable of producing a peak output of
131 SPL on axis at 1 meter. It shall handle 500 Watts of
amplifier power (AES Standard) and shall have a nominal
impedance of 8 Ohms.
In biamped mode, the low frequency section shall meet all
passive mode performance criteria. In addition, the high fre-
quency section in biamped mode shall produce a Sound Pres-
sure Level (SPL) of 106 dB SPL on axis at 1 meter with a
power input of 1 Watt, and shall be capable of producing a
peak output of 135 SPL on axis at 1 meter. The high fre-
quency section in biamped mode shall handle 200 Watts of
amplifier power (AES Standard) and shall have a nominal
impedance of 12 Ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 15mm thickness void-free cross-grain-
laminated Baltic birch plywood and shall employ extensive
internal bracing. It shall be finished in black catalyzed poly-
urethane. Input connectors shall be dual Neutrik NL4 Speakon.
The system shall include a switch allowing it to be operated
in biamp or passive powering mode. The following mount-
ing/suspension hardware shall be provided: five three-posi-
tion flytrack (2 each top and bottom, 1 back); ten 3/8"-16
threaded mounting/suspension points (3 each top and bot-
tom, 2 each per side), four threaded points (back) to mount
an Omnimount Series 300; a recessed cup to accept a
standmount pole (bottom).The front of the loudspeaker shall
be covered with a vinyl coated perforated steel grill backed
with open cell foam to protect against dust.
The two-way full range loudspeaker shall be the EAW model
JF260e.
