PSI Audio of Switzerland has been developing and manufacturing loudspeakers since 1977. The goal has never been to make a nice sound but to reproduce sound perfectly.

Artists and sound engineers spend a lifetime improving their art and designing the best possible sounds for others to enjoy. Therefore they only want to transform the electrical signal into an acoustic signal as accurately as possible so that the listener can hear and appreciate all the beauty and details. This involves:

• Flat frequency response
• Linear phase response
• Controlled membrane (driver) movement
• Reproduction of a square wave - all speakers are time aligned above 150 hz
• 100% analog technology
• Individual calibration of each loudspeaker
