Line Array Column Loudspeaker with EN54:24 Certification

Line Array Column Loudspeaker with with Sixteen 50 mm (2 in) Drivers and EN54:24 Certification

The CBT 100LA-LS, with Constant Beamwidth Technology™, represents a breakthrough in pattern control consistency, utilizing complex analog delay beam-forming and amplitude tapering to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor column speakers.


·       Patent-pending Constant Beamwidth Technology™ provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing.

·       EN54-24 Compliant (when installed with included MTC-PC2 panel cover).

·       Vertical pattern coverage switchable between 40° for medium-throw coverage and 15° for long-throw applications.

·       Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode.

·       Dynamic SonicGuard™ overload protection

·       Swivel (pan)/tilt wall bracket included.

·       Built-in 70V/100V transformer, plus 8 ohm direct capability.
