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. This loudspeaker is EN 54-24 Compliant for life safety applications.




  • Patent-pending Constant Beamwidth Technology™ provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing.
  • EN 54-24 Compliant for Life Safety Applications (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.
