JBL COLUMN 2 WAYS SPEAKER ME 6X6,5 LF

When connected to a CBT1000 line array column speaker, the CBT1000E 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, 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.
