Alumine Three 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.

Alumine Three SE

As with other speakers in the Alumine line, the Stenheim Alumine Three is also available as a Special Edition, the Alumine Three SE, with several upgrades for the most discerning audiophile. Launched at the end of 2022, this SE version builds on the already remarkable sound produced by the standard Alumine Three and gives it even more clarity and detail.


It employs the same sophisticated cabinets and drivers but the wiring connecting the internal components is custom-sourced from a boutique supplier. It features a no-expense-spared crossover, built with the finest available components. Whilst the standard Alumine Three’s crossover is already exactingly and meticulously engineered to be musically unobtrusive, it is nonetheless possible, through the selection of even higher-grade components, to release a whole new level of musical information: greater resolution, richer textures, more articulate rhythms and more natural dynamics.


 All these modifications have been arrived at through exhaustive A/B listening tests. These have led us to select the very best parts from Mundorf and Jantzen, Audyn, Myflex and Jupiter – a Who’s Who of boutique audiophile brands. The result is even greater transparency and dimensionality, even more natural separation and perspectives, micro-dynamic and harmonic resolution, a greater range of tonal colour.


Finally, the binding posts have been upgraded and doubled up. They are now the same as those used on our Reference models and allow for bi-wiring and bi-amping, giving owners the chance to further enhance the sound from their system, or giving them a possible upgrade path in the future by adding further amplifiers.


The Alumine Three SE is the best Alumine Three that we can make and the astonishing sound it produces will only go to further enhance the reputation of what, in the guise of the standard Alumine Three, is already a remarkable, award-winning loudspeaker.

Rating for [object Object]

Deliciously Crispy

Strikingly agile, room‑filling sound is the Alumine Three’s calling card, pairing authoritative, controlled bass with crystalline, natural mids. Built around a full‑aluminium cabinet and a phase‑coherent 3‑way crossover, reviewers from Best of High End and Audiophilepure praised its dynamic responsiveness, high sensitivity and phase-coherent crossover, which make a luxury speaker unusually easy to drive.

Audiophilepure

"I regard this as proof that a well-engineered speaker need not be difficult to drive."

Pros

  • Exceptional dynamic responsiveness — scales with high-power amplifiers yet remains lively with low-watt tube or class‑A amps.
  • Natural, coherent midrange and detailed treble from the dedicated 5" mid and soft‑dome tweeter, yielding stable imaging and lifelike timbre.
  • Authoritative, well-controlled bass with quoted extension to ~32Hz thanks to dual 8" woofers and a front laminar port.
  • Luxury, rock‑solid build — full aluminium cabinet, dual chambers and audiophile-grade crossover parts reflect high-end engineering and finish.

Sound Quality

93/100

Bass

93/100

Dual 8" woofers and a front laminar port with a quoted 32Hz response deliver authoritative, well-controlled lows. Reviewers did not flag lack of deep extension or need for a sub and praised low-frequency weight and control; fits the large-tower band ceiling.

Mid

94/100

Phase-coherent crossover and a dedicated 5" mid produce coherent, natural mids. Review comments ("well-engineered," engaging even with low-watt amps) point to accurate timbre and strong vocal presence through the crossover.

Treble

92/100

1" soft-dome tweeter with claimed extension to 35kHz yields refined, extended treble; reviewers report detail without horror stories of brightness or glare.

Soundstage Imaging

92/100

Phase-coherent design and reviewer impressions of engagement imply wide, well-layered soundstage with stable imaging; performs well across recordings and amp types.

Dynamics

95/100

Reviewers highlight exceptional dynamic responsiveness — scales with high-power amplifiers yet remains exciting with 25W class‑A or 22W SET. High sensitivity (93dB) supports punch and headroom.

Show Less

Build Quality

94/100

Full aluminium construction, substantial 70kg cabinet, dual chambers and high-grade crossover parts reflect luxury engineering. Reviewer notes the living-room-friendly, top-tier luxury-class finish and careful design.

Features Connectivity

80/100

Passive baseline applied. Sensitivity (93 dB) and benign impedance make these easier to drive than many exotic top-tier models; no additional connectivity features reported.

Value for Money

68/100

Performance is excellent, but the listed price (~39,800) places the Alumine Three in a rarefied luxury bracket. Review praise is strong, but steep MSRP reduces mainstream value appeal.
