The CBT 70JE-1 Extension is an add-on module designed for use with the CBT 70J-1 line array column speaker. It features a reinforced baffle and, when connected to the CBT 70J-1, extends the bass frequency response, enhances pattern control, and increases overall sound output levels. The combined system employs Constant Beamwidth Technology, which uses analog beamforming and amplitude tapering to achieve consistent vertical coverage across the listening area. This technology minimizes narrow vertical beaming and out-of-coverage lobing commonly observed in passive column speakers.
