JBL CBT-70J-1 Full-Range J-Shaped Speaker System

Constant Beamwidth Technology Two-Way Line Array Column with Asymmetrical Vertical Coverage. With improved mounting bracket for enhanced aiming flexibility and stronger grille.

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.
