Only you know where your story begins, and who knows where it will take you?
With the A21-M, you certainly know what you hear: a precise replica of what the sound was intended to be.

PSI Audio New A21-M (2022)

“The quality and fundamental accuracy of the 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

Perfect Stereo Image

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.

Expand the bottom end

While the A21-M already reaches down to 38 Hz, its low end can be extended further by adding one or two subwoofers to the system. An A225-M or a pair of A125-M subwoofers will unleash the full potential of the A21-M at any listening level, translating its accurate reproduction qualities into the lowest registers.

A21-M – The perfect compact 2-way studio monitor

Sitting comfortably in between typical midfield systems and traditional nearfield monitors, the A21-M packs the punch of the larger speakers while retaining a comfortably compact size. It performs well in both scenarios, making it the perfect solution for studios who require the power of a midfield system without having the space for one.
