The D&B B4 Subwoofer is an actively driven cardioid subwoofer that houses two long-excursion neodymium drivers in an integrated cardioid arrangement. This setup features a 15-inch front-facing driver in a bass-reflex design alongside a 12-inch rear driver housed in a two-chamber bandpass configuration.
The resulting cardioid dispersion pattern eliminates unwanted low-frequency energy behind the system, which significantly minimizes the reverberant field and ensures exceptional accuracy in low-end reproduction. Engineered exclusively for ground-stacked setups, the B4 subwoofer is an ideal rental option for clubs, theatres, and DJ performances.
