JBL CBT 1000E Extension for CBT 1000 Column Speaker – Black
The JBL CBT 1000E is a purpose-built low-frequency extension module that transforms the CBT 1000 column speaker into a full-range system capable of deep, controlled bass output. This fiberglass-reinforced enclosure pairs seamlessly with the CBT 1000 via included coupler plate, delivering the low-end extension needed for larger venues and demanding applications without compromising the column's compact form factor.
