Stenheim Alumine Five SE

The Stenheim Alumine Five SE is a reference-grade floorstanding loudspeaker that builds on the success of the acclaimed Alumine Five and elevates it even further. By preserving the clarity, coherence, and musical communication that define the Alumine line, the Five SE delivers greater scale, deeper insight, and a more immersive connection to the music.

Building on a proven foundation

Visually and technically, the Alumine Five SE carries the unmistakable Stenheim DNA. Its elegant thin-wall aluminum cabinet, clean proportions, and absence of visible fixings immediately signal its heritage. However, this shared design language goes far beyond appearance and directly shapes the speaker’s exceptional sonic performance.

Advanced three-way architecture

The Alumine Five SE uses a refined three-way design with treated pulp cone bass and midrange drivers paired with a sophisticated fabric dome tweeter. Although the system is more complex than its smaller siblings, the crossover is meticulously engineered to maintain phase coherence and a non-reactive, amplifier-friendly load. As a result, the speaker remains easy to drive while delivering higher efficiency and wider bandwidth.

Precision aluminum cabinet construction

The cabinet is precision-machined from solid aluminum plates and reinforced with internal braces and baffles to maximize rigidity. In addition, carefully radiused twin slot ports reduce air turbulence, while multi-layer damping treatments suppress mechanical resonance. Consequently, stored energy and coloration are kept extremely low, allowing music to emerge with clarity and speed.

Special Edition crossover refinement

What truly defines the Alumine Five SE is its cost-no-object crossover. By using the finest components from boutique suppliers such as Mundorf, Jantzen, Audyn, Myflex, and Jupiter, Stenheim unlocks a higher level of resolution and transparency. Therefore, textures become richer, timing more precise, and dynamics more natural and expressive.

Scale, control, and musical freedom

With twin 10-inch bass drivers and thin-wall cabinet construction, the Alumine Five SE behaves acoustically like a much larger speaker. It delivers deeper bass, greater dynamic range, and faster transient response, yet remains agile and controlled. Moreover, its flat impedance and high sensitivity allow amplifiers to perform at their best, preserving micro-dynamics and emotional nuance.

Optimized placement and stability

Independently loaded bass drivers and slot ports provide excellent in-room behavior and bass control. Stainless steel spikes and footers ensure stable placement while allowing precise adjustment of height and angle. As a result, setup becomes more accurate, and the speaker’s full performance potential is easier to realize.
