d&b B22 Sub-Bass Loudspeaker

The d&b B22-SUB is a ground-stacked subwoofer housing two long-excursion 18-inch neodymium drivers in a bandpass horn cabinet, built for large-format sound reinforcement. Standard mode runs from 37 to 90Hz, while INFRA mode extends down to 32Hz to complement other d&b subwoofers. Deployed in multiples of three, cabinets can be arranged as a Cardioid Subwoofer Array to cut low-frequency energy radiating behind the system.
