PKO Studios, PSI Audio A23-M

“Swiss speaker gurus PSI Audio have never failed to impress us with their technical innovations, and their latest model is no exception!
The natural details of female voices and higher‑pitched acoustic instruments, if they have survived the tracking and mixing processes, are reproduced spectacularly. And if they haven’t survived the tracking and mixing processes, the problems are obviously revealed.
Phil Ward, Sound on Sound UK

Handmade tweeter + midrange driver

The handmade tweeter used on the A23-M has already made the success of our biggest 3-way studio monitor, the A25-M.
To achieve the ultimate precision for this compact 3-way, it was also necessary to build our own midrange driver.
After more than 2 years of analyses and development, we are proud to release the current version: the most accurate and transparent mid that you can find on the market.
Tri-powered with our own analogue amps (Class G/H for bass + midrange driver and Class A/B for the tweeter), the A23-M is the top of the art active compact 3-way studio monitor. It is dedicated to music recording, mixing and mastering, broadcast and post production.

Extend the low frequencies and add power

When used with one of our subwoofers, the A23-M transforms into an amazing 4-way system with ultra-precise control on all the frequencies, from the very low end up to the highest notes.

Add our compact Sub A125-M (two units are required to match the maximum SPL of the A23-M) or our full range Sub A225-M.
