JBL CBT 100LA LS Column Speaker


Provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing


JBL CBT 100LA LS Column Speaker

The black CBT 100LA-LS Line-Array Column Loudspeaker from JBL contains 16 drivers (2” each) and features the Constant Beamwidth Technology which utilizes complex analog delay beam-forming and amplitude-tapering to achieve consistent vertical coverage, avoiding narrow vertical beaming and out-of-coverage lobing. The vertical pattern coverage is switchable between 40° for medium-throw coverage and 15° for long-throw applications. This EN54:24 certified loudspeaker comes with a built-in 70/100V transformer, plus 8 ohms direct capability.
