DESCRIPTION
EAW’s LS832 line source loudspeaker system brings the clas-
sic column speaker up-to-date. Sophisticated frequency shad-
ing integrates the 8x 4-in woofers and 3x 1-in soft dome
tweeters, maximizing the benefits of line source coupling
while eliminating grading lobes.
The system maintains a well behaved nominal vertical cov-
erage pattern of 20
°
to below 630Hz. Even at 500 Hz, the
vertical pattern is still 45
°
. With the enclosure baffle defin-
ing a gentle arc, the drivers form a curved line source to help
prevent the vertical pattern from collapsing in the crossover
region.
At the same time, the drivers act as direct radiators in the
horizontal plane, giving the system an extra-wide 140
°
hori-
zontal coverage pattern with response that meets profes-
sional standards for fidelity and intelligibility.
The internal passive crossover/filter network uses complex,
asymmetrical slopes to integrate the subsystems and goes
beyond merely dividing the signal to perform critical equal-
ization functions.
APPLICATION
Like the classic column speakers of the ‘50s and 60’s, the LS
Series was designed to solve speech-only installation prob-
lems in highly reverberant spaces with low ceilings and hard
floors. These might include small houses of worship, librar-
ies or other civic spaces, and transportation hubs.
The 44.08-in tall, 6.25-in wide enclosure fits nicely on ar-
chitectural columns and can be custom painted to blend in
with any decor. The enclosure includes a comprehensive sys-
tem of 1/4”-20 threaded mounting points for easy installa-
tion.
