The Alumine Five
We are building on success.

Following the critical and commercial success of Alumine Two was a challenging task. It involved building a more prominent, ambitious speaker who maintained the Two’s sense of musical articulation, coherence, and communication. That’s a severe challenge, but it’s a challenge that the Alumine Five mastered spectacularly.

Even a glance will reveal the shared DNA: the classical proportions of the elegant, thin-wall cabinet, the drivers that are just a little larger than you expect, the clean styling, and the absence of visible fixings. There’s no doubt that this is a Stenheim speaker – even before you listen to it. 

That DNA goes much deeper than the way the Alumine Five looks. It informs every aspect of its design and every element of its remarkable performance. Far more significant than the Alumine Two, the thinking and technology in the Five are almost identical. The latest treated pulp cone bass and mid-drivers are paired with a sophisticated fabric dome tweeter. The crossover relies on the same carefully engineered topology, ensuring smooth driver transitions, a non-reactive load, and the absence of damaging out-of-band artifacts. The beautifully engineered cabinet is precision machined from aluminum plates, with internal baffles and braces to increase rigidity and stainless-steel hardware further to ensure consistency. The twin slot ports and braces are carefully radiused to reduce turbulence in the enclosed air volume. The cabinet walls are treated with the same multi-layered, low-volume damping materials to kill mechanical resonance.

Even more importantly—and despite the added complexity of its three-way topology—the crossover has been exhaustively engineered and relentlessly fine-tuned to maintain the phase coherence and non-reactive, low-loss load characteristics that are the foundation of Alumine Two’s lucid clarity and naturally organized musical presentation. 

The result is a speaker that offers the same easy load, low stored energy, and low coloration levels. But it combines them with even higher efficiency and broader bandwidth – to potent musical effect. Despite being the same size as (or smaller than) its immediate competition, the advantages of thin-wall cabinet construction mean that in acoustic terms, the Alumine Five is much larger. At the same time, the twin 10” bass drivers provide a greater swept area. Together, those things add up to a massive musical advantage. A speaker that goes deeper, louder, quicker, offers more detail and dynamic range – and is easier to drive! 

You hear it in the musical scale and power the Alumine Fives can deliver. You also listen to it in their agile, responsive, and articulate performance. Their flat impedance characteristic and high sensitivity make them easy to control, giving your amplifier a far more straightforward job. That allows the system to preserve the micro-dynamic nuance and subtleties in the playing, the relationship between instruments, and the emotional range in a singer’s voice. The Alumine Fives embrace the performance and carry it alive and (when necessary) kicking right into your listening room.

Along with all that musical and acoustical power and energy, you also get responsivity. The Alumine Five’s bass drivers are independently loaded and slot-ported, offering superior bandwidth, dynamics, and remarkable control and in-room behavior. The stainless steel spikes and footers ensure stable placement,  adequate mechanical grounding, and precise control over the speakers’ height and attitude, critical factors in maximizing their performance potential.

At Stenheim, we don’t just want to know what our speakers are capable of. We want every customer to experience their full performance for themselves.  

These speakers are designed right from the start to work with your system and your room, with one goal in mind: delivering more music from your recordings – all of your recordings, all of the time. Big enough to handle the most demanding music, with a natural sense of scale and musical purpose, the Alumine Fin goes just as small and intimate as the musicians, the performance, and the recording demands. It’s not just as much speaker as many listeners will ever need – it’s more music than many thought possible.
