The d&b audiotechnik B4 is a compact cardioid subwoofer engineered for precise, controlled low-frequency reinforcement from a single amplifier channel. Its clever hybrid design couples a forward-firing 15-inch driver in a bass reflex chamber with a rear-firing 12-inch driver in a bandpass chamber, delivering strong, musical punch to the audience while significantly reducing energy on stage and behind the cabinet. Expect fast, articulate response from around 40 Hz up to common crossover points near 100–150 Hz, helping keep open microphones and stage wash under control. Standard NL4 connectivity ensures seamless integration with professional touring and installed systems. This listing includes a hooded flight case for robust protection in transit and quick access on site, ideal for busy rental operations. The B4’s high output, excellent directivity and consistent, repeatable performance make it a smart choice for live music, theatre, corporate events and houses of worship where impactful, well-managed sub-bass is essential. Supplied as a single B4 subwoofer with a protective hooded flight case for efficient transport and deployment.
