A triumph of form marrying function, MUON is perhaps the most extraordinary loudspeaker ever conceived.

MUON is the result of KEF engineering prowess combining with world-class industrial design by Ross Lovegrove. The Muon is limited to an edition of 100 pair.

A KEF Concept designed by Ross Lovegrove

The MUON project is ambitious to say the least. Visionary designer Ross Lovegrove was tasked with turning the finest acoustic engineering into the ultimate loudspeaker by combining form and function with manufacturing integrity. The MUON loudspeaker is fabricated from super-formed aluminium to create a shape that is devoid of sharp edges and extremely stiff. It combines Ross Lovegrove's design aesthetics with KEF's finest engineering. The process by which MUON was 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 makes it perfectly suited to its purpose.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
