JBLCBT50LA1B - JBL CBT 50LA 1 8x2inch Line Array Column Speaker 20degree Black Image 3

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.

Product 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.
