JBL CBT 70JE-1
Best low-frequency extension for professional line array sound systems.
This extension cabinet is the essential partner for achieving true full-range depth in a line array setup. By anchoring the low end down to 45 Hz, it transforms a mid-focused column into a powerhouse, though you will need to account for the extra vertical footprint in your installation.
