The d&b audiotechnik B4 is a compact cardioid subwoofer engineered for precise, controlled low-frequency reinforcement from a single amplifier channel. Its innovative hybrid design pairs a forward-firing 15-inch driver in a bass reflex chamber with a rear-firing 12-inch driver in a bandpass chamber. The result is impactful, musical bass to the audience with markedly reduced spill on stage and behind the cabinet, helping keep open microphones cleaner and stage wash to a minimum. Operating effectively from around 40 Hz to typical crossover points, the B4 delivers fast, articulate response and excellent directivity. NL4 connectivity ensures straightforward integration into professional touring and installed rigs. This listing includes one B4 subwoofer supplied with a hooded flight case, providing robust protection in transit and quick access on site—ideal for busy rental houses and touring packages where dependable turnaround matters. A strong choice for live music, theatre, corporate events and houses of worship, the B4 offers high output, consistent coverage and well-managed sub-bass where it counts.
