d&b audiotechnik B22-SUB – High-Performance Subwoofer

The B22-SUB is a robust, high-performance subwoofer designed for ground-stacked applications. It features two 18” long-excursion drivers housed in a bandpass horn cabinet, delivering impressive sound pressure levels and extended frequency response. Perfect for large-format sound reinforcement, the B22-SUB excels in delivering powerful, precise low-end performance in demanding environments.

In INFRA mode, the B22-SUB seamlessly complements other d&b subwoofers by extending the system’s frequency range, providing deeper, more accurate bass. When used in multiples of three, the B22-SUB can be arranged in a Cardioid Subwoofer Array, achieving impressive directivity control and significantly reducing unwanted rearward sound energy, enhancing clarity and precision in large venues.

Built to last, the B22-SUB features a rugged marine plywood cabinet with an impact-resistant finish, ensuring durability and reliability in any setting. The front of the enclosure is protected by a rigid metal grille backed with acoustically transparent foam for added protection and sound transparency. For ease of transport and setup, the B22-SUB includes four ergonomic handles, rear-mounted wheels, and two runners on the bottom panel to protect the enclosure from scratches. The top panel is designed with recesses to securely stack units, preventing movement during setup.
