JBL CBT 50LA-1
Compact Line Array Column Loudspeaker, Black

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.  
 
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.
•  Swivel (pan) / tilt wall bracket included.
