The JBL CBT 100LA-1 Line Array Column Loudspeaker utilizes 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.
The slim, compact design fits well into virtually any architectural decor. The 39.4" tall line array height provides consistent pattern control throughout the intelligibility band, making the CBT 100LA suitable for challenging acoustic environments. The combination of excellent sound quality, pattern control, and compact design makes CBT 100LA suitable for applications such as lecture halls, transit centers, conference rooms, cathedrals, multipurpose spaces, architectural spaces, and in-wall recessed locations.
The innovative coverage adjustability allows switching between broad and narrow vertical coverage settings to allow matching the coverage and throw requirements of the application. Coverage can be easily switched in-venue with the speaker already installed. This allows a single loudspeaker model to perform in a wide variety of project types.
The voicing can be set to match the application through the Music/Speech switch. 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 shielded drivers feature dual neodymium magnets to cut down the weight. Copper capped pole pieces lower the driver inductance and flux modulation, resulting in increased high frequency extension and reduced distortion at high drive levels. Butyl rubber surrounds provide long life even in high humidity environments.
Dynamic SonicGuard 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. A wall-mount bracket is included, plus ten M6 inserts on the back panel accommodate third-party mounting brackets, or can be utilized to suspend the speaker using forged shoulder steel eye bolts, providing installation versatility.
The CBT 100LA-1 Loudspeaker can be installed either indoors or outdoors. The drivers are weather-treated, and the fiberglass reinforced ABS cabinet is excellent for outdoor applications. The stainless steel external screws and the painted aluminum grille resist rusting in harsh conditions.
