JBL Professional CBT 100LA-1 Constant Beamwidth Line Array Speaker – Black

Description Constant Beamwidth Technology™ Line Array Column Loudspeaker with Sixteen 50 mm (2 in) Drivers. With improved mounting bracket for enhanced aiming flexibility. The CBT 100LA-1, 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 of JBL Professional CBT 100LA-1 BlackPatent-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 protectionSwivel (pan)/tilt wall bracket included.Built-in 70V/100V transformer, plus 8 ohm direct capability.Applications of JBL Professional CBT 100LA-1 BlackLecture Halls / AuditoriumsIts constant beamwidth technology provides consistent vertical coverage, which helps maintain intelligibility even in tall, reverberant spaces.The speaker’s switchable voicing (speech vs music) makes it ideal for spoken word (lectures) and occasional musical or multimedia presentations.Conference RoomsThe narrow or medium vertical dispersion options (switchable between ~15° and ~40°) help direct sound precisely across tables or audience areas, minimizing reflections.Clean, controlled speech delivery is enhanced by the “speech” voicing mode, which boosts mid-range presence for clarity.Transit Centers / Public SpacesIn places like train stations or transit hubs, you often need long-throw and even directivity to reach distant areas. The 15° mode allows for long-throw PA usage.The slim form factor lets the speaker blend into architectural elements rather than being visually intrusive.Cathedrals / Houses of WorshipHard surfaces in such spaces often lead to long reverb times. By using tight vertical control and distributing columns, you can improve speech intelligibility without exciting the reverberant field too much.Its compact, tall design is less visually intrusive and more elegant for historic or architecturally sensitive environments.Multipurpose Rooms / Multi-Use SpacesSince the speaker supports both speech and music modes, it’s suitable for spaces that host varied events (meetings, performances, presentations). JThe switchable vertical coverage gives flexibility depending on seating arrangement or room configuration.In-Wall or Recessed InstallationsIts slim shape and mounting options (with many M6 inserts) make it possible to install in-wall or recessed without drastically altering aesthetics.This is particularly useful for installations in corporate offices or architectural projects where visual integration matters.Outdoor / Semi-Outdoor InstallationsWhile primarily designed for installed sound, the CBT 100LA-1 is built with weather-treated drivers and a fiberglass-reinforced ABS cabinet, so it can handle some outdoor or semi-outdoor environments.Stainless steel screws and a rust-resistant aluminum grille make it more robust in harsher conditions.Distributed Sound Systems (100V / Constant-Voltage Systems)It supports transformer taps (70 V / 100 V) 8Ω direct drive, which is very useful for distributed PA systems in large buildings, malls, or transportation hubs.This makes it ideal for paging, background music, or voice alarm systems where many speakers are spread across zones.Specifications of JBL Professional CBT 100LA-1 BlackDriversSixteen 50 mm (2 in) Full-RangeFrequency Range (-10dB)80 Hz – 20 kHzCoverage AngleVertical: Switchable, Narrow Mode: 15° (±10°), Broad Mode: 40° (±10°), Horizontal: 150°(±20°)SensitivityNarrow: (speech mode) 96 dB (2 kHz – 14 kHz )(music mode) 93 dB (300 Hz – 18 kHz)Broad: (speech mode) 93 dB (2 kHz – 14 kHz)(music mode) 90 dB (300 Hz – 18 kHz)Impedance8 ohms (in Thru mode)Power Rating325 W (1300W peak), 2 hrs200 W (800W peak), 100 hrsMaximum SPL (1m)Narrow: (speech mode) 121 dB cont ave (127 peak)(music mode) 118 dB cont ave (124 peak)Broad: (speech mode) 118 dB cont ave (124 peak)(music mode) 115 dB cont ave (121 peak)Transformer Taps120W, 60W, 30W (15W at 70V only), and 8Ω thru, via switchEnclosureFiberglass reinforced ABS cabinet, painted aluminum grilleOutdoor CapabilityIP-55 rated, per IEC529, when installed with optional MTC-PC2 panel cover.
