Stenheim To Premiere Reference Ultime Passive At High End

Stenheim’s world renowned Reference Ultime just got a whole lot more accessible and you can experience it in Atrium 4.1 / E106 at this years High End Show in Munich says the Swiss company’s recent press release.
Built entirely in Switzerland, the Reference Ultime Passive embodies the same external low-frequency crossover configuration as the original active model, but by adopting a passive network, it halves the amplification requirement and significantly lowers the cost of owning this loudspeaker system.

Building on the established cabinet and driver technology developed for the active version, the Reference Ultime Passive shares the same precision machined, critically damped aluminium cabinet, with its six, separate, sealed chambers, D’Appolito driver array and rear facing, bi-polar radiating bass-units. It also shares the massive MTM sub-baffle, complete with optional motorized toe-in adjustment, allowing precise adjustment of the toe-in axis for the midrange and high-frequency units, despite the 240kg/530lb mass of each speaker.

Rather than opting for exotic materials and « buzz-word » technologies, Stenheim has chosen to rely on established materials, highly evolved and coupled to powerful motor systems : proprietary multi-layer cones are paired with textile surrounds, a specially coated silk dome tweeter and a ribbon UHF unit, ultimate expressions of traditional driver technologies.
