Introducing the B22: a multipurpose omnidirectional subwoofer from d&b audiotechnik. The B22-SUB houses two 18” neodymium drivers in a very efficient bandpass horn design producing high Sound Pressure Levels and an extended frequency response.
The B22-SUB is the largest d&b omnidirectional subwoofer, but when used in multiples of three and in CSA mode (Cardioid Subwoofer Array), they exhibit impressive rejection towards the rear. To increase flexibility, the B22-SUB can also be operated in INFRA mode, which extends the frequency response to supplement other d&b subwoofers. When used as an infrabass system, the B22-SUB performs down to 32 Hz, with an upper operating range of 68 Hz, compared to the standard mode, which operates from 37 Hz to 90 Hz.
“The B2-SUB needs no introduction,” said d&b Product Manager Marcus Bäumler. “Demand for the B2 has been constant since it’s launch in 1994, but cabinet design and modelling has come a long way since then. The B22-SUB exploits the high output power of the d&b D80 amplifier to the full. It has familiar B2 characteristics, but with higher performance and a modern twist.”
