The most accurate 3-way studio monitor ever

A brand new and innovative midrange driver entirely developed and manufactured in-house brings the A25-M even closer to absolute perfection. Imagine hearing sound as naturally as in real life. The speakers disappear, you trust what you hear and let your ears work with total confidence. That’s what you get with the A25-M!

Your success story with the A25-M

Only you know where your story begins, and who knows where it will take you? 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 – you can just move through the natural sound stage and manipulate its elements, always in full control of what you are doing. Become one with the music through the most accurate monitor speakers on the market.

The power of EXD

Our Extended Dome Driver (EXD) keeps the advantages of both dome and cone construction types while eliminating the disadvantages.

When applied to the midrange, dome drivers tend to become either unstable in the middle of the dome, or too heavy due to more rigid material being used, and they can only ever offer a very limited bandwidth in the low end. Cone drivers, on the other hand, pose a relatively large weight in their composition of membrane, dust cap, spider and suspension, which limits SPL and can cause distortion. They also restrict airflow with heavy basket designs. Even the dust cap can add distortion to the reproduction.

Our EXD midrange driver developed for the A25-M, however, combines a 4-inch, latex-and-graphite-infused paper cone membrane with a light polypropylene dome, both of which 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. To further improve its performance, the new driver is built directly onto the rotatable baffle with no basket at all.
