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.
