The d&b audiotechnik B22-Sub is a multipurpose omnidirectional subwoofer, housing two 18-inch neodymium drivers using an efficient band-pass horn cabinet configuration.

Derived from the B2-Sub – after more than 20 years of service – the B22-Sub promises increased performance, a modern appearance and improved internal cabinet bracing. It is the largest d&b omnidirectional subwoofer, and when used in multiples of three and in CSA mode (Cardioid Subwoofer Array), exhibits high rejection towards the rear. It 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 32Hz, with an upper operating range of 68Hz, compared to the standard mode, which operates from 37Hz to 90Hz.

‘The B2-Sub needs no introduction,’ says 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.’
