The CLA37 is an economical solution for exceptional delity in
speech reinforcement and background music applications. It
is especially suited for small to mid-sized spaces with excessive
reverberation or problematic sound reections. The drivers and
system voicing are designed to maximize vocal range clarity
and speech intelligibility without compromising the broadband
frequency response required for pleasing music reproduction.
The CLA37 uses sophisticated, frequency shading to progressively
shorten its acoustic length with increasing frequency. The result is
a well-behaved nominal vertical beamwidth of 30° to below 1 kHz
that eliminates troublesome lobing. In the horizontal plane, the
drivers act as direct radiators. A waveguide loads the three center
drivers to maintain the nominal 120° beamwidth at
high frequencies.
The included bracket allows setting the enclosure’s vertical angle
for both wall-mounting and suspension. An optional input panel
is tted with an integral transformer for 70 V or 100 V distributed
applications. The cross-ply laminated birch enclosure is available
in either black or white nish and the powder coated steel grille is
foam-backed to hide the drivers from view. The entire loudspeaker
is fully tested at the time of manufacture and is warranted to be free
from defects in materials and workmanship for a period of ve years
from the date of purchase.
