JBL CBT 50LA-1 Line Array Column Speaker with Constant Beamwidth Technology
for Music or Speech Applications
The JBL CBT 50LA-1 line array column loudspeaker features JBL's patent-pending Constant Beamwidth Technology™ that provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing.
The JBL CBT Series line array column speakers with Constant Beamwidth Technology™ break new ground in performance, versatility, and affordability. This 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. 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.
The CBT 50LA-1 can be switched between Music and Speech settings, making it perfect for performance or dialogue. The Music setting provides flat frequency response, while the Speech setting produces a mid-range presence boost to provide clear, intelligible speech even at the longest throw distances. The CBT 50LA-1 also includes Dynamic SonicGuard™, which minimizes distortion at high drive levels by limiting low-frequency excursion dynamically. This maximizes clarity at high drive levels while protecting the drivers from damage due to overpowering.
The slim, compact design fits well into virtually any architectural decor. The combination of superb sound quality, excellent pattern control, and compact design make CBT 50LA-1 ideal for retail stores, conference rooms, lecture halls, or any large area where you need clear, full-coverage, balanced sound.
