1 K

State of the Art

The Reference 1 K - the current flagship of our Reference K family! The best speaker we have ever built - we are mighty proud of that. With this imposing and at the same time noble floorstanding speaker you make a statement in your home. Your performance is as serene as it is self-confident in all nuances of sound and at all levels. In order to meet even the most extreme dynamic demands, the 3-way bass reflex speaker is equipped with our best drivers: the powerful 308 mm woofers with aluminum-ceramic tungsten cones provide in the double pack for incomparable dynamics with unbridled drive and enormous low frequency response. With the large cabinet volume behind it and the new "Bass-Guide" bass reflex system, the Reference 1 K delivers truly impressive low-frequency reproduction down to below 20 Hertz. However, thanks to the low-loss wave surrounds that sandwich the midrange and woofer, and the superbly resolving ceramic tweeter, the Reference 1 K shine with excellent fine dynamics even at low volumes. The acoustically optimized cabinets with their characteristic bow shape and organically curved side walls set standards in terms of radiation behavior, stability and low resonance.

Technology at its best

Both technically and structurally, we put an enormous amount of effort into the Reference 1 K. Consequently, the Reference 1 K cannot be shaken by anything and impresses with its enormous weight of 134 kilograms per speaker. In the solid, multi-stiffened cabinets made of multilayer laminate, our best loudspeaker drivers with aluminum-ceramic tungsten and aluminum oxide ceramic cones, heavyweight, sound-optimized crossover components and the highly effective base construction with Bass Guide ensure the highest possible fidelity. The Reference 1 K is equipped with a high-quality biwiring/ biamping connection terminal, allowing the woofer and mid-high range to be driven separately with different amplifiers or with specialized cables. 24 carat gold-plated, stable screw terminals with a capacity for cable cross-sections up to 10 mm2, ensure optimum signal transmission. The levels for the midrange and treble can be finely adjusted at the connection terminal, depending on personal preferences or room acoustic conditions.

Attention to detail

We develop and manufacture the loudspeaker systems of our Reference K Series in our factory in Weilrod in the Taunus region. This is the only way we can maintain the necessary quality standards, minimize tolerances, eliminate any errors, and keep the high sound requirements for our top products. The Reference 1 K cabinets are made of high-quality 50 millimeter multilayer laminate. In an elaborate special process, the characteristic bow shape of the speaker is milled from solid material. The noble, high-gloss surface finish "Piano Finish" is applied, sanded and elaborately polished in twelve work steps. It gives the Reference 1 K cabinet an overwhelming sense of depth. Acoustically optimized two-piece fabric covers, which are elegantly held in place on the baffle by magnetic fasteners, round off the elegant appearance.

A good choice

For a perfect connection with your amplifier(s), the CantoLink 600 speaker cable is a good choice, available in our online store. It is a high-end speaker cable, developed by our partner in-akustik, which tickles the best possible sound quality out of the Reference 1 K. Experience your music in a whole new way via the Reference 1 K and enjoy perfect sound in a classic stereo setup. If you're looking for the ultimate home theater experience: we can help you there, too. Simply combine the Reference 1 K with other models from the Reference K series and immerse yourself in an unparalleled sound adventure.
