When B&O celebrated its 90th birthday with the £54k BeoLab 90 loudspeaker [HFN Dec ' 16] it made a very personal statement about the future of high-end speaker design. Each monumental 137kg polyhedron features 18 drive units and 18 Class D power amplifiers while custom internal DSP integrates the output of the drivers, allowing its directivity to be controlled over 'narrow', 'wide' and 'omni' soundfields to suit the assembled listeners. In addition, a proprietary 'Active Room Compensation' technology uses the same DSP, and external microphone, to optimise its bass performance in-room.
