A & E SPECIFICATIONS
The two-way full range loudspeaker systems shall incorpo-
rate 2x 5.25-in LF transducers and a 1-in soft dome tweeter
HF transducer.
All drivers shall be magnetically shielded allowing the sys-
tem to be used in immediate proximity to video monitors.
The LF drivers shall be mounted in a vented enclosure tuned
for optimum low frequency response. An internal passive fil-
ter network shall provide fourth order acoustical crossover
and system equalization.
System frequency response shall vary no more than ±3 dB
from 98 Hz to 17 kHz at 4 Ohms or 111 Hz to 17 kHz at 16
Ohms measured on axis. The loudspeaker shall produce a
Sound Pressure Level (SPL) of 91 dB SPL on axis at 1 meter
with a power input of 1 Watt, and shall be capable of pro-
ducing a peak output of 119.4 SPL on axis at 1 meter. The
loudspeaker shall handle 175 Watts of amplifier power (AES
Standard). The system shall include an impendance switch
allowing the user to choose between 4 and 16 Ohm opera-
tion (nominal impedance). The system shall have nominal
coverage angles of 120° (h) x 80° (v).
The loudspeaker enclosure shall be asymmetrically tapezoidal
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 dual
Neutrik NL4 Speakon. 2x 3/8"-16 threaded mounting/sus-
pension points (1 each top and bottom) plus 4x 1/4”-20
threaded mounting/suspension points to accept Omnimount
Series 75 shall be provided. 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 two-way full range loudspeaker shall be the EAW model
JF50S. (Specify left or right.)
