The d&b audiotechnik B4 is a compact cardioid subwoofer designed for precise, controlled low-frequency reinforcement from a single amplifier channel. Its hybrid topology combines a forward-firing 15-inch driver in a bass reflex chamber with a rear-firing 12-inch driver in a bandpass chamber, producing impactful, musical bass to the audience while significantly reducing spill on stage and behind the cabinet. Expect fast, articulate response from around 40 Hz up to common crossover points near 100–150 Hz, ideal for keeping open microphones clean and stage wash to a minimum. NL4 connectivity ensures simple integration with professional touring and installed systems.
This listing includes one B4 subwoofer supplied with a hooded flight case for robust protection in transit and quick access on site—perfect for busy rental operations and touring packages needing dependable turnaround. The B4’s high output, excellent directivity and consistent, repeatable performance make it a strong choice for live music, theatre, corporate events and houses of worship where impactful, well-managed sub-bass is essential.
