Looking like they've just jetted off the latest Doctor Who set, Bang & Olufsen's pair of cone-shaped speakers may not be able to climb stairs but they do a mean job of handling anything your stereo may care to throw at them.
The conical contortionism is all down to the BeoLab 9's extraordinary ability to cast balanced sound from anywhere in the room.
In the base lie the 10in bass, and 5in and 4in mid-range units, each in their own dedicated pressure chambers. Meanwhile, atop each set, surveying the vista is a treble tooting Acoustic Lens.
By focussing the sound, the 'lens' is able to project its precious treble in a 180-degree horizontal arc. That has the double bonus benefit of hearing a constant timbre from anywhere in front of the speakers while also reducing troublesome distortion from floor and ceiling reflections.
All makes sense when you think about it, really.
