DIFFUSORI PAVIMENTO KEF MUON

There can be few projects in this World where the central aim is to create an ‘ultimate’. But this was precisely the goal when KEF combined their state-of the-art acoustic technology with the sensual, organic forms of visionary designer Ross Lovegrove.

The Muon loudspeaker is fabricated from super-formed aluminium, which uses a similar moulding process to vacuum forming. The concept uses malleable sheets of heated aluminium to achieve otherwise impossible shapes. The eventual form of the loudspeaker was the result of a careful convergence between Ross Lovegrove’s design aesthetics and the physics of sound. The process by which they were conceived meant that, in effect, Ross Lovegrove was sculpting the sound by ‘skinning’ the technology with purposeful form – the final shape was created through an evolutionary process that ensured it could only be the form that it is.

Since its production, KEF engineers have explored new ways of extracting even more detail and refinement from key KEF technologies in their continuing quest to discover innovative and superior ways of reproducing music with realism and vitality. With the emergence of another iconic KEF model, Blade, KEF engineers were presented with an excellent opportunity of enhancing the technological prowess of Muon even further, namely through the use of the latest iteration of KEF’s landmark innovation, the unique Uni-Q ‘point source’ driver array, and a completely redesigned crossover incorporating all of KEF’s latest thinking to seamlessly integrate all of the drive units.

The effects of this careful re-engineering are impressive, and result in outstanding dynamics, precision and delivery of clearly defined, sonic imagery over a listening area no conventional speaker can rival. Now, even more so than when launched, Muon remains arguably the world’s most extraordinary audio speaker ever conceived and produced, not to mention a truly contemporary art form appropriate for 21st century living. Limited to an edition of just 100 pairs, Muon is unequivocally at the apex of speaker design and technology.
