The B6 SUB is a professional-grade subwoofer developed to deliver powerful and controlled low-frequency reinforcement in ground-stacked loudspeaker systems. Designed with a single high-excursion 18-inch driver in a bass-reflex configuration, the B6 SUB is engineered to meet the demands of large-scale sound reinforcement in touring, rental, and fixed installation environments. Its primary role is to extend the low-frequency response of full-range systems, enhancing overall audio performance in applications where precision and output are essential.

A notable application of the B6 SUB is in cardioid subwoofer arrays, where groups of three or more units can be configured with one cabinet facing rearwards and operated in CSA mode. This setup achieves a focused forward sound projection while significantly reducing unwanted low-frequency emissions to the rear, offering greater control over on-stage and off-stage sound dispersion. Constructed from marine-grade plywood and protected with a durable Polyurea Cabinet Protection finish, the B6 SUB is designed to withstand challenging conditions without compromising acoustic performance. Integrated transport features, including rear-mounted wheels, protective runners, and an optional lid, support operational efficiency in professional environments. The M20 threaded flange allows for pole mounting when required, further increasing deployment flexibility. In demanding live sound and fixed installation contexts, the B6 SUB stands out as a reliable and precise low-frequency reinforcement tool.
