D&B AUDIOTECHNIK B22
-
The d&b B22-SUB is a high-output, ground-stacked subwoofer designed for large-format sound reinforcement. It uses two long-excursion 18" neodymium drivers in a bandpass-horn enclosure, delivering extended low-frequency response and up to 143 dB SPL when powered by current d&b amplification. The B22 can also operate in INFRA mode for extended sub-low reproduction and can be configured in groups of three or multiples of three for Cardioid Subwoofer Arrays (CSA).
