Line Array Column Loudspeaker with with Eight 50 mm (2 in) Drivers and EN54:24 Certification
The CBT 50LA-LS, with Constant Beamwidth Technology™, represents a breakthrough in pattern control, utilizing analog delay beamforming 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. This loudspeaker is EN 54-24 Compliant for life safety applications.
