DESCRIPTION
EAW’s LS432 line source loudspeaker system brings the clas-
sic column speaker up-to-date. Sophisticated frequency shad-
ing and all-pass filtering integrates the 4x 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 1000Hz. Even at 500 Hz, the
vertical pattern is still 80
°
. 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
LS432 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 26-in tall, 6.25-in wide enclosure fits nicely on archi-
tectural 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. The LS432 is available as the LS432-SLT with a 15
°
downward angle to the front baffle, letting the system be
mounted near a higher ceiling without sacrificing coverage.
