DESCRIPTION
A 3-way full range system in a vented, slant-baffle enclo-
sure. Includes 2x 12-in woofers, 2x 7-in midrange cones and
a 1-in exit compression driver on a Wave Guide Plate™. Pow-
ering mode is switchable: passive (3-way crossover) or
biamplified (passive MF/HF crossover). The woodframed cloth
grill is attached with threaded fasteners.
APPLICATIONS
The DS223e is engineered for exceptional high output per-
formance in the nearfield from overhead mounting positions.
True 3-way design dramatically improves the quality of vocal
reproduction. A very effective tools in permanently installed
distributed systems. Comprehensive 3/8"-16 mounting/sus-
pension points. Six Year Warranty.
Applications include:
MultiMedia
Chapel
Dance Club
Live Music Club
Restaurant

ARCHITECTURAL SPECIFICATIONS
The three-way full range loudspeaker systems shall incorpo-
rate 2x 12-in LF transducers, 2x 7-in cone MF transducers
and a 1-in exit compression driver HF transducer.
The LF driver shall be mounted in a vented enclosure tuned
for optimum low frequency response. The MF drivers shall be
mounted in separate sealed subenclosures. The HF drivers
shall be loaded on axis-symmetrical wave guide plates with
a combined nominal coverage pattern of 70°(h) x 100°(v).
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 45 Hz to 19 kHz measured on axis. In passive mode,
the loudspeaker shall produce a Sound Pressure Level (SPL)
of 99 dB SPL on axis at 1 meter with a power input of 1
Watt, and shall be capable of producing a peak output of
132.8 SPL on axis at 1 meter. It shall handle 600 Watts of
amplifier power (AES Standard) and shall have a nominal
impedance of 4 Ohms.
In biamped mode, the passive mid/high frequency section
shall meet all passive mode performance criteria. In addi-
tion, the low frequency section in biamped mode shall pro-
duce a Sound Pressure Level (SPL) of 100.5 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 low frequency section in biamped mode shall handle
700 Watts of amplifier power (AES Standard) and shall have
a nominal impedance of 4 Ohms.
The loudspeaker enclosure shall be rectangular in shape. The
loudspeaker enclosure’s front baffle shall be slanted 20°to
facilitate overhead mounting. It shall be constructed of 3/
4-in medium density fiberboard (MDF) with the exception of
the baffle which shall be of 15mm thickness void-free cross-
grain-laminated Baltic birch plywood. The enclosure shall
employ extensive internal bracing. It shall be finished in
black catalyzed polyurethane. Input connectors shall be a 2-
terminal barrier strip and one Neutrik NL4 Speakon. The sys-
tem shall include a switch allowing it to be operated in biamp
or passive powering mode. A total of twelve 3/8"-16 threaded
mounting/suspension points (4 on top, 3 per side and 2 on
back) shall be provided. The front of the loudspeaker shall
be covered with wood-framed cloth grill.
The three-way full range loudspeaker shall be the EAW model
DS223e.
