VERTUS CLA was created with the thought
of integrating professional line array

technology in an extremely compact and
elegant speaker column.

Compared to the traditional two-way speakers,
the sound is distributed much more evenly
throughout the audience, both in outdoor
and in indoor environments acoustically difficult
or reverberating as well. The CLA cylindrical
wave front boasts the pleasant effect of present
and precise forwardly projected sound. Even
acoustic feedback towards microphones is
reduced.
VERTUS CLA is a light and compact modular
line array system created for both live and fixed
installations, comprised by two products:

- CLA 604a: bi-amp two-way active column
speakers 400 + 100W RMS

- CLA 208Sa: active subwoofer 600W RMS

CLA604a is an extruded aluminum
column speaker fitted with 6 x 4” custom
woofers and 4 x 1” dome tweeters, each
coupled to a wave guide. The internal Class D
amplification, 400W for woofers and 100W

for tweeters with switch mode power supply

and DSP processor with 4 equalization
presets provide unexpected dynamics in a
system of these dimensions.
The rapid latching system with pins allows
for the expansion of the system, doubling­up CLA608a modules to form a unified
column with an absolute and coherent source
integration and increase of SPL and low­frequency directivity control.

CLA 208Sa is a 2 x 8” active subwoofer in
bass-reflex design and birch ply enclosure. The

internal Class D amplifier delivers 600W and
is matched with a switch mode power supply
and a DSP processor with filtering functions,
equalization and speaker protection. Created

with the idea of extending the CLA608a’s
low frequency performance in live
applications, the CLA208Sa serves as the base

support for the CLA608a column speaker which
can either be frontally mounted to the sub, as
well as fixed upon the optional stand through
the M20 socket on the upside of the sub.
The CLA208Sa subwoofers are modular as well,
and they can be stacked to enlarge and increase
the maximum SPL.
