CBT 70JE-1-WH White 500W Extension For CBT 70J-1 Line Array Column Speaker

The CBT 70JE-1-WH extends a CBT 70J-1 column speaker (sold separately) into a taller array with deeper bass response and tighter pattern control, in a white finish that matches the white CBT 70J-1 cabinet. Four low-frequency drivers and a dedicated crossover network deliver 500 W of power handling and high sensitivity, pushing bass response down to 45 Hz when combined with the main column. Extended pattern control reaches to 400 Hz for plus or minus 20 degree directional control, and down to 200 Hz for meaningful off-axis cancellation, concentrating sound toward the far end of a room rather than spreading it thin. The tough fiberglass-reinforced ABS enclosure matches the CBT 70J-1's build quality, and an included coupler plate attaches the extension to the top of the main column for a mechanically solid, acoustically matched line array. The combined system carries Constant Beamwidth Technology through to the extended array, keeping directivity control consistent across the full cabinet height. It suits auditoriums, lecture halls, stadiums, and theme parks that already run a CBT 70J-1 and need more low-end reach and output without adding a separate subwoofer.
