The CBT 50LA-1, 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.The slim, compact design fits well into virtually any architectural decor. The combination of superb sound quality, excellent pattern control, and compact (53 cm [20.8 in] tall by 10 cm [3.9 in] wide) design makes CBT 50LA-1 ideal for a wide variety of applications, such as retail stores, concourses, transit spaces, fill applications, conference rooms, architectural spaces, audio for video, lecture halls, and other applications where such a combination is desired.
