JBL CBT 70JE-1-WH Extension for CBT J-1 Speaker - White (Each)
When connected to a CBT 70J-1 line array column speaker, the CBT 70JE-1 Extension provides an 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, utilizing complex analog beamforming 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.
