PSI AUDIO A25M

PSI Audio A25-M: Switzerland's flagship of absolute precision

The A25-M is PSI Audio's flagship three-way active studio monitor, designed for professionals and serious enthusiasts who demand the highest level of accuracy, imaging and neutrality. With breakthrough driver technology and a fully analogue signal path, the A25-M delivers sound so true to the source that the speakers seem to disappear, letting you focus entirely on your mix.

At the heart of the A25-M is an innovative Extended Dome Driver (EXD) midrange, developed and built entirely in-house by PSI Audio, combining the control of a dome with the energy and projection of a cone to deliver exceptional midrange clarity at high sound pressure levels, without distortion or coloration. This advanced three-way architecture provides a flat frequency response from 28 Hz to 23 kHz and a remarkably stable stereo image, ideal for critical listening, mastering and immersive audio work.

The listening experience

The A25-M's greatest strength lies in its bass dynamics and transparency: it faithfully reproduces both the qualities and imperfections of a recording, with no added artifice or colouration. It stays clear and emotionally engaging whether reproducing large orchestral works at high level or intimate small-ensemble recordings, and offers a remarkably stable, precise stereo image. It's a formidable working tool for hearing what's happening below 50 Hz and keeping control of low-end dynamics, which are often the first casualty of an insufficiently revealing monitor during mastering.
