“This loudspeaker seems to be capable of effortlessly making audible the strong emotional expression in music… I think it is indeed the precision of the A25-M that can present musical creativity and technical perfection in productions as a distinguishing feature with its fine dynamics. “

– Fritz Fey, Studio Magazin Germany

Design and Production Like No Other

The A25-M offers you three ways to your goal; three ways to perfection. And if you need to put your speakers on their sides, the tweeter and midrange driver can be rotated to accommodate your preferences.

Then there is the sound that has earned PSI Audio the respect of audio professionals all around the world. Imagine the musicians, the instruments, the notes themselves coming to life right before your eyes, so vividly that you can almost see them, touch them, smell the wood of the guitar, feel the vibration of that string. The A25-M works very hard to make your work easy. Become one with the music through the most accurate monitor speakers on the market.

The release of the PSI Audio A25-M boasts an entirely new midrange driver. The Extended Dome Driver (EXD) combines dome and cone constructions, effectively offering the best of both worlds in the process.

The new driver system is still mounted to a rotatable baffle to enable vertical or horizontal speaker placement at optimum dispersion. Combined with proprietary PSI Audio technologies like the Class G/H amplifiers, CPR, AOI and ALG, the EXD in the all-analogue A25-M achieves the most precise sound reproduction possible.

PSI Audio’s EXD midrange driver developed for the A25-M combines a 4-inch, latex-and-graphite-infused paper cone membrane with a light polypropylene dome, where both are directly connected to the voice coil. With the dimensions and weight ratio of coil and membranes optimised in this way, our EXD offers higher SPL at lower distortion, pushing the new A25-M even closer towards perfect accuracy. Additionally, the new driver is built directly onto the rotatable baffle with no basket at all.

The new A25-M (2021) delivers an incredible 122dB max SPL per pair and reaches as low as 28Hz.
