SWISSONOR LOUDSPEAKERS

A CAREFULLY HANDCRAFTED LINE OF HIGH SENSITIVITY LOUDSPEAKERS

DESIGNED AND BUILT WITH GREAT CARE AND ATTENTION TO DETAIL

TRUE TESTIMONIES OF THE SWISS TRADITION OF TIMELESS DESIGN AND UNCOMPROMIZED QUALITY

HAND MADE - PRODUCT OF SWITZERLAND

The basic idea was the design of a high-efficiency loudspeaker combining several contradictory requirements allowing reproduction of living music as vector of intense emotions

 

  • Relaxed listening of all music styles, from very low to very high levels.

  • The use of amplifiers covering all power classes, explosive dynamics even with tube amplifiers with power as low as 8 W per channel. A second input allows use of solid state (transistor) amplifiers without loss of damping.

  • Reproduction of infinite details, without projection, due to use of a single point source. This feature brings better spatial reproduction fidelity, too. A simple equalizing network improves linearity without adding phase shift.

  • Full size panoramic sound (horizontally and vertically). The controlled directivity results in a smooth polar diagram in both planes.

  • Good dynamics thanks to high efficiency combined to correct power rating. That’s the only way to avoid the audible thermal compression of classic loudspeakers.

  • Easy placement, near a wall or even a corner. The 2 π environment is integral part of the loudspeaker design. The fine-tunable bass reflex opening allows optimized integration in rooms of different size, adsorption rates and listening distances.

  • Less excitement of room resonance and echoes due to controlled directivity and high efficiency. This can be explained by the (to easily forgotten) physical law of energy continuum.

  • Long term reliability and value conservation due to oversized long-life components. All parts have been selected by numerical simulation, measuring and during hundreds of listening hours using objective and subjective quality criteria.
