The JBL's CBT50LA LS is a line array column loudspeaker with Constant Beamwidth Technology employs analogue delay beam forming and amplitude tapering to achieve consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are common with passive column speakers with a straight form factor. The sleek, compact shape blends perfectly with almost any architectural style. This public address system has the combination of excellent sound quality and pattern control, as well as its compact design, makes it suitable for a wide range of applications.
