“The quality and fundamental accuracy of the psi a21-m extends all the way through the audio band. Voices and acoustic instruments sound just as they should. Stereo imaging is really sharply focussed and precise. The new tweeter is a success also…”

– Phil Ward, Sound on Sound

Design and Production Like No Other

Stereo is more than just volume differences between the left and right channels. Phase relations are paramount to determine the accurate position of a signal in the acoustic space – and hence equally important in the development of PSI Audio speakers. The accurate phase alignment provided by PSI Audio CPR technology recreates the vivid spatial listening experience as it was intended.

Instrument placement, reverb envelopes, even compression artefacts are easy to identify with the phase-corrected reproduction of PSI Audio speakers.

The active crossover, with integrated “CPR”, gives the psi A21-M unprecedented impulse behaviour – with excellent stereo imaging. The crossover is also optimized for maximum phase coherence, projecting a wide horizontal and vertical ideal listening area.

The powerful bi-amplified output stages feature the unique “AOI” output stages and has a protection circuit, which can be monitored via the red LED on the front panel.

The electronics are housed in a unit mechanically isolated from the speaker cabinet to avoid resonance at high sound pressure levels.
