The Experience

“The sound that I heard /.../ suggests that these speakers are among the best"
Jim Hannon, The Absolute Sound

By elevating the act of listening to new heights, Estelon delivers an audio experience like no other. At the forefront of this sound revolution is our signature speaker – Extreme. The system comprises an upper and a lower module, with the former fully adjustable to best suit a room’s acoustic attributes and the listener’s personal preferences.

With its soaring, handcrafted cabinet and sleek two-tone finish, the speaker system is a statement piece, but one that doesn’t need to shout about its achievements. Indeed, the Extreme has been designed to perform a smart disappearing act when in use: instead of having your ear drawn to the speaker, the listener is immersed in sound, experiencing music afresh in all of its nuanced splendor.

The Experience

An exhilarating audio experience.

Following the success of our Rolls-Royce-inspired Extreme Legacy Edition, we have applied the same acute levels of attention to our passive series to create the Estelon Extreme Limited Edition.
A bespoke variant of our eye-catching Extreme speaker system, the Extreme Limited Edition boasts all of the technological and design advantages of our flagship model, with a heightened sensibility to detailing that is found in only the finest of luxury products.

Standing at up to two meters in height and capable of adjusting to the exact dimensions of its environment, the Extreme Limited Edition combines sculptural elegance with a quality and authenticity of performance that is second to none.
The Limited Edition is finished in Dark Silver metallic paint and features hand-polished stainless-steel rims, which encircle each of the system’s drivers. Produced in strictly limited numbers, each speaker is personally signed by Estelon’s founder and Chief Designer Alfred Vassilkov, pinpointing the degree of detail that underscores this exceptional speaker system.
