JBL CBT 70J

The CBT 70J, 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-ofcoverage 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-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, 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
•	Wall bracket included.
