TECHNICAL SPECIFICATIONS LS832
DIMENSIONAL DRAWINGS
DIMENSIONAL DRAWING ARCHITECTURAL SPECIFICATIONS
The two-way full range loudspeaker systems shall incorpo-
rate eight 4-in LF transducers and three 1-in soft dome tweeter
HF transducer.
All eleven drivers shall be mounted in a vertical column to
create a line source. The LF drivers shall be mounted four
each above and below the three HF drivers. An internal fre-
quency shading filter set shall maximize beneficial line source
coupling while minimizing grading lobes. An internal pas-
sive filter network shall provide fourth order acoustical cross-
over and system equalization between the low and high fre-
quency sections.
System frequency response shall vary no more than ±3 dB
from 200 Hz to 20 kHz measured on axis. The system shall
produce a Sound Pressure Level (SPL) of 97 dB SPL on axis at
1 meter with a power input of 1 Watt, and shall be capable
of producing a peak output of 126.0 dB SPL on axis at 1
meter. The system shall handle 200 Watts of amplifier power
(AES Standard) and shall have a nominal impedance of 12
Ohms.
The loudspeaker enclosure shall be rectangular in shape with
a convex arc to the front baffle. 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 polyurethane. Input connec-
tors shall be two-terminal barrier strip. A total of 6x 1/4"-20
threaded mounting/suspension points (1 each top, bottom,
4 back) shall be provided. The front of the loudspeaker shall
be covered with a vinyl coated perforated steel grill.
The 2-way full range loudspeaker shall be the EAW model
LS832.
