JBL CBT 70J-1 Passive Column

The CBT 70J-1, with Constant Beamwidth Technology™, represents a breakthrough in pattern control consistency, utilising 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.

• Improved mounting bracket for enhanced aiming flexibility
• Comes with stronger, improved grille
• Swivel (pan) / tilt wall bracket included
