CBT 70J-1-WH - Jbl Loudspeaker Line Array Column White

Purpose-Designed Extension for CBT 70J-1 Line Array Column Speaker. With stronger grille. When connected to a CBT 70J-1 line array column speaker, the CBT 70JE-1 Extension provides extended bass response, extended pattern control, and increased sound output levels. The combined array system provides Constant Beamwidth Technology(TM), 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.
