The white CBT 70J-1 from JBL is a 2-way line array column loudspeaker, ideal for use in auditoriums, lecture halls, stadiums, theme parks, and more. The unit features four 5" high-power low frequency drivers and sixteen 1" soft dome tweeters to provide plenty of power and a wide frequency response. The asymmetrical vertical coverage provides consistent front-to-back sound levels, while the patent-pending Constant Beamwidth Technology provides constant directivity and reduces out-of-coverage lobing. The vertical pattern coverage is switchable between 45° and 25°, allowing you to choose the best use for medium-throw or long-throw applications. Switchable voicing provides a flat response in music mode and a mid-range presence boost in speech mode to accommodate music and speech programs. Built-in SonicGuard technology provides overload protection for HF devices. This model includes an improved mounting bracket that affords enhanced aiming flexibility and a stronger grille.
