YOUR SUCCESS WITH THE WORLD’S MOST PRECISE MAIN MONITORS

Our main monitors and full-range speakers are designed for professional recording studios, mixing and mastering engineers, and producers who demand absolute accuracy. These big speakers deliver exceptional precision, a very detailed soundstage, and a flat frequency response from 20 Hz up, ensuring reliable decisions at every level.

As professional loudspeakers for mixing and mastering, they reveal every nuance with confidence – from the deepest bass to the finest transient detail – making them some of the best speakers for critical listening, large control rooms, and high-end studio environments.

“These are the most accurate speakers I have heard with my own ears.
Listening to them, especially for extended periods of time, is truly a revelation. “

THE POWER OF EXD FOR A PERFECT MIDRANGE CLARITY

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 A226-MAIN 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.

TECHNICAL DATA

For studio monitors, flatness is fundamental: you don’t want “smiley-face” tuning (e.g. boosted bass and treble) that might sound pleasant but misrepresents the mix. Flat response helps you judge balance, EQ, and spatial placement properly.

Every PSI Audio monitor is individually measured and calibrated in our full-size anechoic chamber.

We fine-tune each unit by hand until it reaches the exact linear frequency response defined in our reference curves.

Your monitor ships with its personal measurement sheet — a unique fingerprint of its precision and a guarantee of uncompromising Swiss-made accuracy.

PSI Audio now offers the main studio monitor A226-MAIN with the option to externalize its electronics as the new APA-700 in 29″, 3 U. The external Analogue Power Amplifier (APA) grants easy access to all controls when the monitors are soffit-mounted.

HANDMADE IN SWITZERLAND

All our products are handcrafted in Switzerland with passion and attention to detail.

Manufacturing by hand allows to match and adjust components so that tolerances cancel each other out instead of building up, as is often the case in industrial production.

A226-MAIN – WHO IS IT FOR?

The A226-MAIN is the real thing, its immaculate reproduction easily qualifies this speaker for every application that requires absolute accuracy – particularly mastering and sophisticated mixing.

Since the A226-MAIN plays back source material with such natural clarity, it is also perfectly suited for particularly demanding personal listening environments.

Provided enough room to allow an appropriate listening distance, the A226-MAIN can be used for pretty much everything.

WHAT OUR USERS SAY

The first time I heard them, I couldn’t believe my ears. I’ve never heard such richness, such precision. When you listen to a live track, you feel like you’re there.
Everything is perfect: an unbeatable stereo image, very precise bass and a very natural midrange with great depth..
