Kaiser Acoustics Kawero Minal – Flagship Loudspeakers Weighing Nearly 300 kg

German company Kaiser Acoustics has introduced the Kawero Minal, a new loudspeaker system that immediately makes it clear we are dealing with a product designed without compromise. Even from its dimensions, weight, and overall architecture, it is obvious that this is not merely an expensive pair of floorstanding speakers, but a model aimed squarely at the upper High End segment. The Kawero Minal now takes the top position in the brand’s Kawero lineup.

One of the key features of the new model is its enclosure, built around the principle of maximum mechanical stability and effective resonance suppression. At its core is the German material Panzerholz, used in the company’s proprietary multilayer sandwich construction. This wood-based composite is valued for its extremely high density, rigidity, dimensional stability, and pronounced damping properties. In a number of respects, it approaches metals, while still retaining the advantages of a wood-based composite material.

The design also incorporates a heavy damping film intended to further reduce parasitic vibrations. In a loudspeaker of this class, this is no longer just an impressive technical detail, but an essential part of the model’s engineering philosophy. The manufacturer is clearly betting on the idea that cabinet control and the suppression of unwanted resonances have a direct impact on the final sound character.

The Kawero Minal is a 3-way, 4-driver system, and its driver complement looks highly impressive even by the standards of large floorstanding loudspeakers. The configuration includes a 12-inch bass driver in a bass reflex enclosure, a 10-inch low-frequency driver in a sealed chamber, a 6.5-inch midrange driver in its own separate sealed enclosure, and a proprietary ribbon tweeter developed in-house. The latter is mounted in a waveguide whose parameters were calculated using FEM.

All drivers except the tweeter are manufactured by Audiotechnology specifically for this model. The description places particular emphasis on large voice coils, high magnetic force, and low moving mass. The driver cones are made from mineral-filled polypropylene. This approach usually indicates an effort to achieve a combination of good sensitivity, precise control, and large-scale presentation without a sense of heaviness or inertia.

The high-frequency module has also been engineered to a very serious standard. The new ribbon tweeter is fitted with a silver-foil membrane developed with the participation of Greek company Ypsilon Electronics. The crossover uses Duelund CAST Cu components, while the filter itself is described as a flat crossover with an emphasis on correct behavior in both the time and frequency domains. All of this points not only to a focus on expressive timbre, but also to precise phase coherence and a convincing recreation of soundstage space.

According to the stated specifications, the Kaiser Acoustics Kawero Minal covers a frequency range of 30 Hz to 30 kHz, has a 4-ohm impedance, and a sensitivity of around 93 dB at 2.83 V measured at a distance of one meter. The system measures 141.3 × 52.8 × 74 cm, while its weight reaches 286 kg. These figures alone show that this is not a loudspeaker intended for an ordinary living room or for general-purpose use, but for a serious system requiring space, careful installation, and suitably matched amplification.

In the end, the Kawero Minal looks like a typical representative of that High End segment where everyday convenience and versatility take a back seat to uncompromising engineering, costly materials, and an extremely ambitious execution. The new model is already on sale in Europe at a recommended retail price of 150,000 euros per pair.
