Our No.5.1 loudspeaker is designed to transport you into the center of a live music experience. The concept behind this speaker is to produce music without any restrictions in terms of dynamic range, frequency spectrum or reproducibility.
Aided by the natural radiance of superbly crafted woods, this loudspeaker model enriches your living space and delivers outstanding sonic results for any type of music reproduction. The music sounds as direct and natural as when it was performed on the stage or in the studio.

In the No.5.1 loudspeaker, the midrange frequencies are reproduced using a 4” driver. The lower the mass of the driver, the faster and more accurate its response will be. The low total mass of the driver enables a seamless integration of the crucial mid frequency range with the plasma tweeter.

The bass is handled by two 8.7” long throw drivers. These can achieve a membrane displacement of +/- 22 cm. Despite its unobtrusive dimensions, the No.5.1 can produce a solid bottom end, well beyond the usual at home volume levels. The meticulously crafted enclosure with sandwiched layers is the basis for the loudspeakers outstanding audio performance. The sandwich design, with flatly glued high efficiency damping material alternated with sound absorption panels, ensures the energy radiated into the enclosure is dispersed very effectively, there is no opportunity for the cabinet to develop any resonant response of its own. A high quality bi-wiring terminal is provided on the back so that the tweeter can be acoustically matched to the room characteristics. With an efficiency rating of 91 dB, the No.5.1 model is also a very forgiving loudspeaker.
