Stenheim Alumine Two.Five

The Stenheim Alumine Two.Five builds on the foundation of the Alumine Two, but audibly takes the concept to a higher level. Where the Two already impresses with speed and naturalness, the Two.Five adds extra scale, control and bass foundation – without losing its elegance or musicality.

As we have come to expect from Stenheim, the housing is made entirely of solid aluminum panels. This ensures an extremely stiff, low-resonance construction. The result: a speaker that responds very quickly, produces an uncolored midrange and flawlessly exposes micro dynamics. The Two.Five sounds free, open and unforced – even at higher volumes.

More scale, more foundation

The Two.Five is a 2.5-way design with a carefully tuned crossover. Compared to the Alumine Two, it offers a fuller low range and more authority in larger rooms. Yet the character remains recognizable: speed, precision and a strikingly realistic representation of voices and acoustic instruments.

Thanks to its relatively high sensitivity, the Alumine Two.Five can also be easily combined with high-quality tube or transistor amplifiers with modest power. This makes it particularly versatile in high-end systems.

Musical control

What is immediately noticeable is the balance between control and expression. The bass reproduction is tight and defined, never cumbersome or exaggerated. The midrange is transparent and rich in detail, while the highs present themselves as airy and refined – without sharpness. The spatial image is stable and deep, with natural instrument placement.

The Alumine Two.Five is therefore a speaker for the enthusiast who is looking for refinement, but also wants to experience impact. A model that effortlessly grows with the quality of the rest of the system.
