About JBL

The JBL CBT 50LA-1-WH Line Array Column Loudspeaker (White) features Constant Beamwidth Technology, so it's well-suited for use in lecture halls, transit centers, conference rooms, cathedrals, multipurpose spaces, architectural spaces, in-wall recessed locations and more. This technology reduces the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor passive column speakers.

This flexible, compact speaker is built for indoor and outdoor usage and has controls for switchable voicing (music or speech). This model features an improved mounting bracket, which when used affords greater flexibility in aiming the speaker.

JBL Features

  • 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
