Your Success Story with the A23-M

Only you know where your story begins, and who knows where it will take you? But with the A23-M, you are prepared for everything. You can even rotate the tweeter and midrange driver to fit your studio perfectly!

Then there is the sound that has earned PSI Audio the respect of sound professionals all around the world. Building on the renowned A25-M, PSI Audio has created a more compact A23-M that retains the outstandingly accurate, mastering-grade audio reproduction. Assess the entire frequency range effortlessly even without a subwoofer – although you can opt to enhance the A23-M with a Sub A225-M, of course. Whatever story you need to tell, the A23-M helps you along the way – and once you have heard it, you certainly will not go back.
“There is nothing other than first-place with the A23-Ms. I highly recommend them.”

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.

Picture
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.

A23-M Studio – Who is it For?

The A23-M is the perfect 3-way active studio monitor mainly dedicated to mixing, thanks to its ultimate transparency and accuracy. The midrange frequencies are easier to place in the mix thanks to its own dedicated handmade driver.

Though it can be used for any applications, most of our customers use the A23-M for mixing, producing, mastering or in post-production.
Picture
“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.
”

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.
