Constant Beamwidth Technology™ Line Array Column Loudspeaker

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 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. The voicing can be set to match the application through the Music/Speech switch, conveniently located on the side of the cabinet. The Music setting provides flat frequency response, while the Speech setting produces a mid-range presence boost to provide clear, intelligible speech even at the longest throw distances. The drivers feature dual neodymium magnets for light weight. Copper-capped pole pieces lower both the driver inductance and the flux modulation. This increases highfrequency extension and reduces distortion at high drive levels. Butyl rubber surrounds provide long life even in high humidity environments. The drivers are shielded. Dynamic SonicGuard " minimizes distortion at high drive levels by limiting low frequency excursion dynamically. This maximizes clarity at high drive levels while protecting the drivers from damage due to overpowering. A swivel (pan) / tilt wall-mount bracket is included and ten M6 inserts on the back panel fit the spacing of common mounting brackets, or can be utilized to suspend the speaker using M6 forged shoulder steel eyebolts, providing versatility of installation. CBT 50LA-1 can be installed either indoors or outdoors. The drivers are weathertreated, the fiberglass reinforced ABS cabinet with UV resistant paint is excellent for outdoor applications, external screws are stainless steel, and the painted aluminum grille resists rusting in the harshest conditions.

  • Patented Constant Beamwidth Technology™

Electronics can be large, heavy, and expensive and you probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.
