B22 Subwoofer

The B22 SUB is a high-performance subwoofer designed by d&b audiotechnik to deliver substantial low-frequency output for professional audio systems in large-scale environments. Built around two high-excursion 18-inch drivers housed within a bandpass horn enclosure, the B22 SUB provides significant sound pressure levels and an extended frequency response. This makes it particularly well suited for concert venues, outdoor events, touring applications, and fixed installations requiring powerful and consistent low-end performance. The B22 SUB can also operate in INFRA mode, enhancing sub-bass extension when integrated with other d&b subwoofers, thereby broadening the overall system’s frequency range. For environments requiring controlled directivity, multiple B22 SUB units can be arranged in a cardioid configuration, significantly reducing rearward sound dispersion and minimising noise pollution behind the array. The robust enclosure is constructed from marine-grade plywood and finished with a weather-resistant paint to endure demanding professional use. Protective design features, including a rigid metal grille, stacking recesses, transport handles, and rear wheels, ensure durability and efficient handling during setup and transport. As part of the d&b system approach, the B22 SUB integrates seamlessly with d&b amplification and control infrastructure, supporting optimal performance and system coherence. The B22 SUB is a reliable solution for professionals seeking precise, high-impact sub-bass performance across a wide range of sound reinforcement scenarios.
