JBL CBT Series

JBL CBT Series

Ushering in a new era for passive column speaker technology, based on years of extensive research conducted by Harman engineers, the JBL CBT Series line array columns with Constant Beamwidth Technology breaks new ground in performance, versatility, and affordability. Designed for venues that would typically use larger point-and-shoot speakers, the CBT models incorporate technical advancements that allow them to vastly outperform competitive systems,
with a level of user-friendliness that virtually eliminates the challenges of delivering great sound.

CBT 50 LA

The CBT 50LA, 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.
Full fidelity bandwidth.
Dynamic SonicGuard™ overload protection
Built-in 70V/100V transformer, plus 8 ohm direct capability.

CBT 100 LA

The CBT 100LA, with Constant Beamwidth Technology™, represents a breakthrough in pattern control consistency, utilizing complex analog delay beam-forming and amplitude tapering to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor column speakers.

Features :

Patent-pending Constant Beamwidth Technology™ provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing.
Vertical pattern coverage switchable between 40° for medium-throw coverage and 15° for long-throw applications.
Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode.
Dynamic SonicGuard™ overload protection
Wall bracket included.
Built-in 70V/100V transformer, plus 8 ohm direct capability.
