JBL CBT 70J-1-WH Line Array Column Loudspeaker (White)

Product Overview

The JBL CBT 70J-1-WH is a two-way passive line array column loudspeaker for installed-sound rooms that need high output and consistent coverage from a compact enclosure. It combines sixteen 25 mm tweeters and four 125 mm low-frequency drivers in a coaxial arrangement with JBL Constant Beamwidth Technology for even vertical coverage and reduced out-of-coverage lobing. Asymmetrical vertical coverage and switchable 45°/25° patterns let integrators tune throw for medium- or long-distance applications. Finished in white, it suits houses of worship, auditoriums, and multi-purpose rooms.

Product Description

The CBT 70J-1 uses complex analog delay beam-forming and amplitude tapering to deliver smooth, consistent vertical coverage that straight passive column speakers cannot match. Its asymmetrical vertical coverage directs more energy toward the rear of the room to even out front-to-back levels. A switchable voicing control offers flat response for music or a midrange presence peak for speech. Vertical coverage is switchable between 45° for medium throw and 25° for long-throw applications. Dynamic SonicGuard overload protection guards the high-frequency devices under sustained output, and the included swivel (pan)/tilt wall bracket allows precise aiming. The 70J-1 can be paired with the CBT 70JE-1 extension for added low-frequency output and pattern control. Explore related models in our JBL Professional installed audio collection.
