Usually shipped within 2-3 working days
When connected to a CBT 70J-1 line array column speaker, the CBT 70JE-1-WH Extension provides extended bass response, extended pattern control, and increased sound output levels.
The combined array system provides Constant Beamwidth Technology™, which represents a breakthrough in pattern control consistency, utilising complex analogue 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 passive column speakers.
