Line Array Column Loudspeaker with Eight 2" Drivers and EN54:24 Certification
The JBL CBT 50LA-LS is a very compact 50 cm high column that utilizes a straight line of eight 2-inch drivers. It contains low-saturation transformers, so it can be used on 70V/100V distributed speaker lines or as low impedance speakers.
JBL’s CBT Series column loudspeakers were the first loudspeakers to incorporate JBL’s newly introduced and patented Constant Beamwidth Technology, using passive beam-forming components to deliver a narrow vertical beamwidth and constant directivity coverage from a passive column, resulting in high intelligibility in difficult acoustical venues and consistent frequency response at every listener location.
In addition, the CBT speakers provide Dynamic SonicGuard overload protection circuitry, which reduces distortion at high drive levels, along with user variable voicing which allows for selecting a flat frequency response or a midrange presence peak for, especially clear speech intelligibility.- Features
