A loudspeaker that is extremely rare to see live – and even rarer to hear: On September 4, 2026, the KEF Muon will be our guest for a single day.
We are taking advantage of this special visit for a complete Fidelity x KEF Day. In addition to the Muon, you can expect various KEF series, active loudspeakers, and selected combinations with Hegel electronics in our listening studios.
Participation is free. Registration is valid for the entire day – there are no fixed time slots.
A whole day dedicated to KEF and Hegel
For the event day, we are preparing several of our listening rooms with a special focus on KEF and Hegel. This way, you can get to know different loudspeaker concepts and gain an impression of how broad the current KEF portfolio is.
You can look forward to, among other things:
- KEF Reference Series
- KEF R Series
- KEF LS LUXE
- KEF LS60 Wireless
- further active KEF loudspeakers
- various combinations with Hegel electronics
Thus, the day ranges from compact active solutions to large high-end systems.
The highlight: the KEF Muon
There are only 100 pairs of the KEF Muon worldwide. With a pair price of around 230,000 Euros, it is one of the most exclusive loudspeakers in the KEF portfolio.
On Thursday, our pair will be delivered, on Friday you can experience them with us – and immediately afterwards, the Muon will continue its journey as part of the Muon Tour.
We are deliberately presenting the loudspeakers in our open area. This way, as many visitors as possible will have the opportunity to see and hear the Muon up close.
Every hour on the hour, we will play the KEF Muon – presented by KEF Germany sales.
The KEF Muon is much more than just an exceptional high-end loudspeaker. It was created in collaboration with renowned industrial designer Ross Lovegrove and combines KEF's loudspeaker technology with an almost sculptural form. The housing is made of superformed aluminum and has virtually no sharp edges – a design that not only looks extraordinary but is also intended to reduce disruptive diffraction effects.
The Muon is limited to only 100 pairs worldwide and currently costs 230,000 Euros per pair. This makes it one of the most extraordinary loudspeakers in the KEF portfolio, not only technically but also in terms of manufacturing, design, and exclusivity.
Listen, compare, and ask questions
The Fidelity x KEF Day is intended as an Open House.
You can drop in anytime between 12:00 PM and 6:00 PM, move freely through our studios, listen to different systems, and, of course, explore our regular exhibition.
Staff from KEF and their German distributor GP Acoustics will also be on-site to answer questions about the loudspeakers, technologies, and various series.
There is no fixed schedule you need to adhere to. You decide when you arrive, how long you stay, and which systems you want to listen to.
Do you want to experience the Muon more intensely?
This event is about giving as many music and hi-fi enthusiasts as possible the opportunity to experience an extraordinary loudspeaker live.
An open event naturally cannot completely replace an individual high-end demonstration under optimal conditions.
If you are seriously interested in the KEF Muon and would like a more detailed personal consultation or demonstration, please contact us. We will then work together to find a suitable option.
