The d&b audiotechnik B4-Sub is a compact, high-performance cardioid subwoofer built for touring productions and fixed installations that demand precise low-frequency control. Its hybrid 15-inch and 12-inch driver arrangement delivers tight, musical bass with impressive pattern control, greatly reducing spill on stage and behind the array for cleaner mixes and better gain before feedback. Rated at 500 W RMS at 6 ohms, the B4-Sub integrates seamlessly with d&b system amplifiers and processing, ensuring optimal protection, tonal consistency and maximum output from a small footprint. NL4 connectors provide fast, reliable hook-up, while the rugged, tour-ready enclosure is engineered to withstand the rigours of the road and daily hire cycles. As a low-end partner to d&b J-, Y- and Q-Series systems, it excels in festivals, live music venues, theatre, corporate events and premium club installs where clarity, punch and predictable coverage are essential. Choose the B4-Sub when you need cardioid performance and high headroom without resorting to large sub arrays.
