Product Overview

The JBL CBT 50LA-1 is a compact passive line array column loudspeaker for small to mid-size installed-sound rooms that need clear speech reinforcement and even music coverage. Eight 50 mm drivers combined with JBL Constant Beamwidth Technology deliver consistent vertical coverage and reduce the out-of-coverage lobing typical of straight passive column speakers. Switchable music/speech voicing and built-in 70V/100V transformers make this column speaker adaptable for distributed audio in commercial spaces. Finished in black, it works well in conference rooms, multi-purpose rooms, and houses of worship.

Product Description

The CBT 50LA-1 applies analog delay beam-forming and amplitude tapering to produce smooth vertical coverage from a slim column form factor. A switchable voicing control offers flat response for music or a midrange presence peak for speech-focused applications. Built-in 70V/100V transformers plus 8-ohm direct operation allow integration on constant-voltage lines or low-impedance amplifier channels. Dynamic SonicGuard overload protection helps preserve the high-frequency section under sustained output. An improved swivel (pan)/tilt wall bracket is included for flexible aiming during installation. See related models in our JBL Professional installed audio collection.
