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

Constant Beamwidth Technology Line Array Column Loudspeaker with Sixteen 1-Inch and Four 5-Inch Drivers - Black The CBT 70J-1, with Constant Beamwidth Technology, represents a breakthrough in pattern control consistency, utilizing complex analog delay beam-forming and amplitude tapering to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor column speakers.Features: Asymmetrical vertical coverage sends more sound toward far area of room to make front-toback sound levels more consistent. Components: Sixteen 25 mm (1 in) soft dome tweeters and four 125 mm (5 in) high-power LF drivers, arranged coaxially. Patent-pending Constant Beamwidth Technology provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing. Vertical pattern coverage switchable between 45 for medium-throw coverage and 25 for long-throw applications. Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode. Dynamic SonicGuard overload protection of HF devices Swivel (pan) / tilt wall bracket included.
