JBL CBT 70J-1 Constant Beamwidth Technology™ Two-Way Line Array Column with Asymmetrical Vertical Cove
The CBT 70J-1, with Constant Beamwidth Technology™, represents a breakthrough in pattern control consistency, utilizing complex analogue 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. (shown with included grille removed)
- Asymmetrical vertical coverage sends more sound toward a far area of a room to make front-to-back sound levels more consistent.
- Components: Sixteen 25 mm (1 in) soft dome tweeters and four 125 mm (5 in) high-power LF drivers,
- 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
- 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.
