The cabinet is constructed in typical Stenheim fashion. It uses solid aluminium panels over a critically braced, internal chassis, CNC machined from solid billet aluminium. The sheer quantity of aluminium employed is impressive, ensuring that these cabinets are sonically inert and will not flex, no matter how loud the music gets. Beneath the sleek outer panels, each driver is mounted in its own chamber to minimise interference from the others.
Like all the Reference Line models, the Reference Ultime Two is a full d'Appolito design, with a symmetrical driver layout conferring significant sound dispersion advantages. It uses a pair of 30 cm (12-inch) forward-firing woofers to provide deep bass from 25 Hz. Control and bass extension is further enhanced through a pair of rear-facing, laminar flow, reflex ports similar to those used so successfully in the award-winning Alumine Five. These have the advantage of reducing the turbulence that can occur with traditional ported designs giving better transie...
Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- Stenheim designs and manufactures speakers featuring robust aluminum enclosures, achieved through precision CNC machining and internal bracing, to minimize cabinet resonance and maximize internal volume.
- These speakers uniquely combine traditional driver materials like coated silk-dome tweeters and pulp-cone woofers with the modern, high-rigidity aluminum cabinets, providing a balance of warmth, detail, and dynamic expression.
- They are intentionally designed with high sensitivity and a stable impedance, making them relatively easy to drive with a wide range of amplifiers, including low-powered tube amplifiers.
- Stenheim emphasizes a strategic collaboration with driver manufacturers like PHL, allowing them to precisely tailor driver specifications, mechanical characteristics, and surface coatings to meet their desired sonic signature.
