JBL CBT 1000E Purpose-Designed Extension Loudspeaker for CBT 1000 (...
Product Overview
The JBL CBT 1000E is the purpose-designed extension loudspeaker for the CBT 1000 line array column, used to increase vertical array length for greater throw and output in larger installed systems. Stacked with a CBT 1000, it extends coverage in deep rooms such as auditoriums, houses of worship, and large multi-purpose spaces. The extension shares the slim black profile of the host column for a consistent architectural appearance.
Product Description
The CBT 1000E adds transducers to the CBT 1000 array, lengthening the column to narrow vertical coverage and project further into a space while preserving the system's Constant Beamwidth behavior. It is not a standalone loudspeaker; it is intended specifically to extend a CBT 1000 host unit. The combined array operates passively and is driven by an external commercial amplifier. The slim enclosure mounts flat to walls in line with the host column. Explore related models in the JBL Professional passive PA speakers collection.
