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 single-ended tube amplifiers with power as low as 4 W per channel |
| - |
Reproduction of infinite details, without projection, due to the placement of the driver diaphragms in a unique coaxial and coplanar configuration. This feature brings better spatial reproduction fidelity, too. In classic coaxial designs, the high-frequency driver diaphragm is situated far behind the low-frequency driver, resulting in huge high-frequency delay. Some loudspeaker-manufacturers introduced complex time-delay networks for the low-frequency driver to compensate this inconvenient. |
| - |
Enhanced listening zone (horizontally and vertically) due to the housings diamond-shaped section, facilitating the angular placement. The controlled directivity results in a smooth polar diagram in both planes. |
| - |
Extreme dynamics thanks to the very high efficiency combined with high power rating. That’s the only way to avoid the audible thermal compression of classic loudspeakers. |
| - |
Easy placement, adjacent to a wall or even near a corner. The 2 p environment is integral part of the loudspeaker design. The fine-tunable bassreflex opening and the discrete adjustable mid- and high range allow optimized integration in rooms of different size, adsorbtion 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. |
