PSI Audio A226-MAIN and A326 D-REX: the full main-monitoring experience

Yverdon-les-Bains, 18th November 2025 – PSI Audio has recently introduced its first main monitor, the A226-MAIN. With the additional extension A326 D-REX, the system reaches a whole new level of impressive audio reproduction.

The full experience: big main monitoring from PSI Audio

The A226-MAIN is PSI Audio’s first foray into main monitor territory, now enhanced even further with the A326 D-REX extension. Mounted on top of each other, or side by side, these speakers provide the classic main monitor experience – but with PSI Audio style Swiss precision. The entire range of the spectrum is reproduced perfectly, with flawless dynamics and outstanding transparency. Combined, the system reaches up to 132 dB, more than enough for even the most demanding situations. This is the winning combination, the ultimate in studio monitoring – the real thing.

Power and precision redefined: A226-MAIN

The first PSI Audio main monitor A226-MAIN is an active, all-analogue, three-way speaker with symmetrically configured 10-inch woofers. It combines the renowned EXD midrange driver with a specifically developed aluminium coil tweeter and the double woofers to cover the entire spectrum from 20 Hz to 23 kHz. More importantly, it covers that frequency range with the utmost accuracy, reproducing the signals exactly as they were intended – a feat arguably more difficult with growing speaker size. The exact acoustic alignment of all involved drivers is one of PSI Audio’s most praised qualities, and the A226-MAIN is a showcase for the manufacturer’s proficiency in handling phase: from an impressive 100 Hz upwards, all frequencies are perfectly aligned.

Extending bass reality: A326 D-REX

Since PSI Audio has mastered the art of aligning phase between multiple drivers, the idea of adding more woofers to the system was quite obvious. The result is the A326 D-REX, which stands for Dynamic Range EXtender. As the A226-MAIN already reaches all the way down to 20 Hz, the term “subwoofer” cannot be reasonably applied to the A326 D-REX. Instead, the three additional woofers support the main speaker in the low frequencies, granting the system a more powerful and hence more dynamic bass response, bringing extra clarity and precision. In tandem, the A226-MAIN and the A326 D-REX become utterly exciting in their remarkably exact audio reproduction. For LFE use, the A326 D-REX offers a special mode that opens its frequency band upwards to 160 Hz – perfectly flat, of course.

Absolute accuracy from the smallest to the largest systems

This commitment to sonic accuracy is not new for PSI Audio. In fact, all speakers from the Swiss manufacture adhere to the ideal of uncoloured, true-to-life sound reproduction. As a result, all models are sonically compatible with each other, making it possible to mix and match speakers of different sizes to build more extensive setups, especially immersive installations. The combination of A226-MAIN and A326 D-REX for the main stereo set can easily be enhanced with another A226-MAIN in horizontal configuration as a center speaker, a few A21-M as surrounds and A17-M as ceiling speakers – and all these speakers will work together just fine, creating one homogenous sound field.

Swiss-precision craftsmanship

This level of compatibility between various models can only be achieved with very narrow tolerances in manufacturing the speakers. All PSI Audio studio monitors are handcrafted by skilled specialists at the company’s own workshop in Yverdon-les-Bains, Switzerland. To underline this commitment to quality, every single speaker is measured and calibrated in the anechoic chamber, and it comes with its very own measuring protocol.
