Jbl Professional Cbt 70JE-1 Column Array Extension

Product Description

The JBL PROFESSIONAL CBT 70JE-1 is a column array extension section designed to expand the CBT 701-1 line array loudspeaker system. This passive extension adds 70 centimeters of additional column length to the base unit, increasing the effective aperture of the array and allowing for tighter vertical coverage control in installed sound applications. It is finished in black to match the base speaker assembly. Installation is handled by professional audio contractors and systems integrators working in commercial and institutional environments.

The CBT 70JE-1 is used in fixed installation settings where the CBT 701-1 column array loudspeaker is deployed and additional vertical pattern control is required. Typical applications include houses of worship, auditoriums, conference rooms, and transportation facilities where intelligibility and controlled dispersion are priorities. This extension pairs directly with the CBT 701-1 base unit to form a longer, more directive column assembly.
