DESCRIPTION

A 2-way full range passive system in a vented slant-baffle
enclosure . In clu d es a 12-in woo fer an d a 1-in exit compres­sion driver on a 90 x 45 constant directivity horn. The
woodframed cloth grill is attached with threaded fasteners.

APPLICATIONS

The DS122e is engineered for exceptional performance in
the nearfield from overhead mounting positions. A very ef­fective tools in permanently installed distributed systems.
Comprehensive 3/8"-16 mounting/suspension points let it
be aimed in the horizon tal and verti cal planes. Six Y ear W ar­ranty.

Applications include:

MultiMedia
Chapel
Dance Club
Live Music Club
Auditoriums
Restaurant

ARCHITECTURAL SPECIFICATIONS

The 2-way full rang e loudspeaker systems shall in corporate a
12-in LF transducer 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 HF driver shall be
loaded on a constant dir ectivity h orn with a n ominal cover­age pattern of 90° (h) x 45° (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 79 Hz to 15 kHz measured on axis. 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. The loudspeaker shall handle 500 Watts of amplifier
power (AES Standard) and shall have a nominal impedance
of 8 Ohms.

The loudspeaker en closure’s fr on t baffle shall be angled 20°
to facilitate overhead mounting. It shall be constructed of
15mm thickness void-fr ee cross-grain-laminated Balti c birch
plywood plywood. The loudspeaker enclosure shall employ
extensive intern al bracing. It shall be finish ed in black cata­lyzed polyurethane . Input connectors shall includ e both a 2­terminal barrier strip and d ual N eutrik NL4 Speakon conn ec­tors. A total of twelve 3/8"-16 threaded mounting/suspen­sion points shall be provided (six on the top, two on each
side and on e each bottom and back). The front of the loud­speaker shall be covered with a wood-framed cloth grill se­cured with threaded fasteners.

The 2-way fullrange loudspeaker shall be the EAW model
DS122e.
