JBL CBT 50LA-1 Constant Beamwidth Technology Line Array Column Loudspeaker,

Constant Beamwidth Technology Line Array Column Loudspeaker with Eight 50 mm (2 in) Drivers. With improved mounting bracket for enhanced aiming flexibility.

The CBT 50LA-1, with Constant Beamwidth Technology, represents a breakthrough in pattern control, utilizing analog delay beam-forming and amplitude tapering to accomplish consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor passive column speakers.


  • Patent-pending Constant Beamwidth Technology provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing.
  • Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode.
  • Dynamic SonicGuard overload protection
  • Built-in 70V/100V transformer, plus 8 ohm direct capability.
  • Swivel (pan) / tilt wall bracket included.
