Performance that honors the performance.

The Reference Ultimate Two is the most compact speaker in the Reference line, but it is still considerably bigger than the Alumine Five and built to a different scale. It is designed for larger spaces and to accommodate more powerful systems, to fill big rooms with dynamic, captivating sound that covers the full bandwidth, providing deeper bass than is possible with a smaller cabinet design. 

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 chamber to minimise interference from the others.  

Like all the Reference Line models, the Reference Ultime Two is a design by Appolito, 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 are 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 transient response, which is crucial for reproducing fast and dynamic musical passages. This speed and attack underlie the exceptional clarity and dynamism with which Stenheim is synonymous. 

The five drivers – two woofers, two midrange, and a tweeter - are kept to the minimum, in common with other Stenheim designs, enabling the crossovers to be simpler than they otherwise might be. Nonetheless, they are the fruit of many hours of listening in the development phase and painstakingly designed to ensure that every driver is working in its optimum frequency range. The passive crossovers are constructed from the very finest electrical components available. This is part of the Reference Line brief, to produce the most captivating music irrespective of cost, and allows us to make our component selection without compromise. 

The Reference Ultimate Two is a room-friendly design that demands considerably less space between it and the rear wall to perform well. Performance in any given room can be optimized using the room control back panel. This enables the highs, mids, and bass to be individually dialed in, allowing the Reference Ultimate Two to be fine-tuned to provide the best possible sound.  

Whilst the Reference Ultimae Two is an imposing speaker, it possesses a classical, slim elegance that enhances multiple décors. It shares the same form factor as its bigger brothers in the Reference Line and the same design philosophy, but looks more at home in smaller rooms. Available in the standard colours of Light or Dark Grey, it can also be ordered in the custom colours of Ivory, Mocha, or Full Black. The metal trim parts that visually divide the cabinet can also be ordered in several colours to match the owner’s system or furnishings. These can also be retro-fitted should your décor change in the future, and you would still like your Reference Ultima Twos to complement it. 

Like all Stenheim speakers, it is hand-built to order in our manufacturing in Switzerland and is designed to deliver captivating music for decades. The Reference Ultimate Two delivers audio performance that honours the musical performance, a listening experience that captures the energy and atmosphere of a live concert and live audience. 

Solid aluminium platform
For Reference Ultima Two 

Reference Platforms are designed to extract the very best from your Reference speakers, be they the Reference Ultimate Two or the Reference Ultimate Three. The platform provides additional height, adjustment, and stability to Stenheim Reference speakers, with the end result being even better sound rendition.

Made from solid aluminium, the Platform configuration creates a much larger footprint that provides more excellent stability to the loPlatformrs. Each arm of the platform is supported by spike that can be height adjusted using a large knob on the top. These knobs require no tools to turn them and so it is very easy to adjust the spikes by hand in tiny increments to find the perfect set-up. Setting the precise height is very important to compensate for floor irregularities, and he speakers can safely be adjusted for tilt fore and aft to obtain a perfect orientation. The platform enables a significant range of adjustment, + or – 2.5cm (2 inches in total), ample for receiving sound.

The Platform also makes it easy to switch from the wheels, which will allow an owner to find the best location for the speakers in the room, to the spikes, which will provide the definitive coupling of the speakers to the ground. It is delivered with three different types of spikes to accommodate various sorts of floors. In addition to standard spikes with their protective shoes, there are long spikes which are designed to penetrate deep pile carpets, as well as steel domes to protect delicate floors. All provide an excellent platform on the ground.

The Platform also provides increased mass, which lowers the centre of gravity and improves the mechanical interface with the floor. This benefits the bass, which is deeper and more detailed, as well as contributing to a bigger and more precise soundstage. The overall impression is that of an even more detailed sound where every nuance can be heard.

The Reference Platform is the perfect partner for Stenheim Reference loudspeakers and allows them to perform at their best.
