Goals

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.
  

  
  


• 
  

  -  Fullsize 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,
  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.
