Exceptional quality in a compact format

With the Alumine Three, Stenheim has distilled the exceptional quality of its world-renowned Alumine Five speaker into a compact housing, creating an even more accessible music experience for audiophiles and music lovers. Made in Switzerland, the new Alumine Three speaker is the product of many years of research and unparalleled knowledge of audiophile technology.

Its design takes inspiration from the Alumine Five, Stenheim multi-award-winning speaker. Like its predecessor, it is an all-aluminium model and shares its core technical specifications, including extremely high efficiency. It can also be combined with high-quality low power amplifiers. However, the Alumine Three’s more compact housing sets it apart, enabling extremely high performance at a lower price point.

Some manufacturers focus on the senses, others on technology. Stenheim’s approach combines the two because we understand the impact of physical constraints on subjective listening quality.

The Alumine Three adopts cutting-edge technology specifically for the benefit of musicians and music. It plunges you into the heart of music as if you’re listening to it live. Listen to the notes vibrate, detect every nuance of the voice, touch or bow movement and feel all of the musician’s feeling and emotion. The Alumine Three has been designed for you to bring music to life.

This is reflected in its timeless, refined design with clean lines and light, neutral shades. Ignoring fleeting trends, the Alumine Three is built to last and, above all, to rediscover listening pleasure.

Press reviews

  • “On Solacium, Trio Mediaeval sings sacred-sounding lullabies in a manner that merges ancient and contemporary modes of expression. The Alumine Threes excelled at reproducing the purity and lively everberant character of Trio Mediaeval’s vocals. Acoustic bass notes were rendered in quick, taut, accurate tones. The Pass Lab-Stenheim combo presented Solacium as a beautiful work of human – scale art, radiant and reverent”

  • “The Stenheim Alumine Three did this more frequently, and do a greater degree that any other loudspeaker I’ve had in my home. The Three is a compact, exceptionally built, and easy to drive loudspeaker that fits into real rooms, with the heart of a large horn system and touches of electrostatic transparency thrown in for good measure. At, or near the top of finest compact loudspeakers available today, and one that joins the small club of products I’d recommend going out of your way to experience”


  • “(…) when I listen attentively , I find that the analytical power of Alumine Three is absolutely superior among the speakers of the same price, because not only the change of music, but also the sound of the pianist’s breathing, and the ultra-thin sounds that are triggered when the keys of the piano move have all manifested themselves.”
