Stage Ultra

The ZELLATON Ultra speakers are a truly bespoke speaker design with three models in the range. The Stage is the company’s first and most physically compact offering, designed for smaller listening spaces.

The drivers used in the Ultra series are extremely costly and take a very long time to manufacture. The manufacturing process is elaborate and requires utmost precision and skill. For example, the diaphragms are baked for two to three weeks with precise timing. Even after each production phase is completed, there is a high rejection rate as the specific requirements for these drivers is at a standard which even utilising the most modern manufacturing methods, is difficult to achieve. ZELLATON’s triple-layer, full cone, sandwich diaphragms are one of a kind and perhaps the most obvious feature that differentiates them from other loudspeaker manufacturers. The purpose of using a three-layer sandwich design is to reduce the sound of the material. The hardened foam consists of millions of various sized, small air bubbles. In fact, 80% of the foam is actually air and that gives the cones their desired lightness and stiffness. Another benefit to this design is the reduction of distortion.

Another somewhat unconventional aspect of the Stage’s design is the crossover. There’s no tuning of the crossover to linearize the speaker. This is instead done with the drivers themselves which consequently eliminates phase shifting issues. After an extensive testing process, ZELLATON selected Duelund’s new proprietary CAST capacitors made at Duelund’s new factory. Everything inside the speaker is connected with Duelund wiring and all internal connections are hardwired. Mundorf M-Connect Silver plated copper binding posts are used on the back of the speaker. These binding posts provide excellent grip when using cables terminated with a variety of spade lugs.

Due to the Zellaton driver technology, the midrange driver is capable of handling a far greater bandwidth than in conventional designs. Therefore, the tweeter is crossed over much higher up the frequency range and the bass driver is crossed over much lower down the frequency range. This means that one driver handles most of the sonic presentation with no crossover in the path of the most critical frequencies. When the cross over does come into play, it is one of the most sonically invisible crossovers that we have ever heard, so the effect is that you are listening to a super high performance wide-bander with top and bottom augmentation. The resulting cohesion, speed and accuracy is simply stunning. This is one of Zellaton’s prime philosophies – make the most capable drivers and use the least amount of them as necessary. This is impossible to do unless you have a driver that is extremely light, stiff and distortion free.

Cabinet fit and finish is nothing less than spectacular. The Stage are finished in the finest quality lacquered piano finish ever used on a speaker. The cabinet design is seamless with no joins, seems, nuts or bolts in sight, a sculpture that anyone would be proud to place in their home. The Stage cabinet is made of a complex sandwich design that incorporates many different layers of materials that result in an unbelievably inert cabinet. Each cabinet is individually measured and tuned. You can tell that the know how to create this level of enclosure has taken generations of development to get to this level. Coupled with serious internal bracing, cabinet vibrations are virtually non-existent. ZELLATON uses a special Laser Doppler vibrometer to measure the speaker’s vibrations down to the square centimetre. ZELLATON eschews conventional philosophy of spiking speakers and prefers instead to use coupling in concert with energy draining.

The ZELLATON Stage Ultra breaks new ground in bringing you closer to the feeling of unfiltered, unadulterated sound. There’s an incredible purity, a reach-out-and-touch-you transparency and remarkable timbral realism through music’s entire range. It also expresses nuanced detail along with the structured, propulsive, macro-dynamic architectural elements of music. There’s presence and three-dimensionality with instruments, voices and spatial cues appearing more fully fleshed out. It is uncoloured, coherent and pure, particularly in the critical midrange where they have a rare ability to convey music that simply sounds like the real thing. All veils are removed between you and the performer.
