The d&b audiotechnik B4 is a compact cardioid subwoofer designed for precise, controlled low‑frequency reinforcement. Its innovative configuration combines a forward‑firing 15-inch driver in a bass reflex chamber with a rear‑firing 12-inch driver in a bandpass design, delivering strong forward output while significantly reducing energy behind the cabinet. Expect tight, musical low end from around 40 Hz up to typical crossover points around 100–150 Hz, with excellent pattern control that helps keep stages and open microphones cleaner. Connectivity is via NL4, ensuring straightforward integration with professional touring and installed systems. This listing includes a hooded flight case, providing robust protection in transport and storage while allowing quick access on site. Ideal for rental companies and touring engineers who need reliable cardioid performance from a single amplifier channel, the B4 offers high output, superior directivity, and consistent results in real‑world venues. A smart choice for live music, theatre, corporate events, or any application where impactful, well‑controlled sub-bass is required.
