The Stenheim Alumine Three SE follows the same core design principles as the standard Alumine Three and is hand-built in Switzerland.. It uses a thin-walled aluminium billet cabinet that maximises internal volume while keeping compact outer dimensions. As a result, the high-efficiency, cellulose-based drivers deliver speed, impact, and a soundstage that feels far larger than expected.
Distinctive design & engineering
Like the standard model, the Alumine Three SE stands apart through its solid aluminium construction and timeless proportions based on the golden ratio. In addition, the cabinet supports a three-and-a-half-way topology, allowing the speaker to combine scale, control, and musical ease across many listening spaces.
Advanced cabinet & driver configuration
Two large bass drivers work with different suspension systems. One focuses on deep bass extension, while the other preserves speed and clarity in the upper bass. Consequently, the speaker delivers wider bandwidth, higher efficiency, and effortless dynamics without sacrificing tonal balance.
Special Edition upgrades
The Alumine Three SE adds carefully chosen refinements that raise performance beyond the standard model. For example, upgraded internal wiring from a boutique supplier improves signal purity and low-level detail. At the same time, the crossover uses premium, no-compromise components selected through extensive listening tests.

Reference-grade components
The crossover now features high-quality parts from leading audiophile brands, including Mundorf, Jantzen, Audyn, Myflex, and Jupiter. As a result, the speaker reveals finer textures, clearer spatial cues, and stronger micro-dynamic expression with greater depth and focus.
Enhanced connectivity & flexibility
The binding posts are upgraded to the same Reference-grade terminals found on flagship Stenheim models. Furthermore, dual terminals support bi-wiring and bi-amping, offering greater system flexibility and a clear upgrade path over time.
The ultimate Alumine Three
By combining the proven foundation of the standard Alumine Three with focused Special Edition upgrades, the Alumine Three SE achieves higher resolution and insight. Above all, it maintains natural musical flow while delivering a more open, detailed, and immersive listening experience.
