The Perfect Low End in Your Studio

The low frequencies are where sound becomes tactile, engulfing listeners in a full-body experience. And while sheer power can certainly create a memory, a truly lasting impact can only be achieved with precision. The A125-M offers this very precision.
Picture
PSI Audio has translated its general approach of unaltered, maximum fidelity reproduction to the bass spectrum, allowing for a riveting experience that will change the way you work. Taking the guesswork out of the bass management, the A125-M grants an accurate representation of what is really going on “down below”. Take control and create a sonic wonderland that reaches throughout the entire spectrum with no insecurities and no need to double-check your work on a different system. Get a subwoofer you can trust.
"The combination of A14-M ​​and A125-M represents an extremely compact full-range interception system with outstanding imaging properties that make listening in the studio a pleasure and promises significantly less exhausting work days."

– Fritz Fey
Studiomagazin (Germany)

This is Not a Subwoofer

At least not in the way most people think about subwoofers. In many cases, the leading questions that govern the development of a subwoofer are “how low can it go?” and “how loud can it go?” At PSI Audio, we did consider these questions, but we added a third one: “how precise can it go?” With typical subwoofers, all you get from the low end is some vague rumble. This can be impressive, but it is not particularly musical.
Picture
With the A125-M, you get the power and the depth, but you also get the punch, the transients, the speed and accuracy that you can expect from a PSI Audio product – which is why we like to think of our subwoofers as “low-frequency precision monitors”.

Add Low End with the Sub A125-M

Our low-frequency speakers are designed and calibrated to seamlessly extend the low end of any of our loudspeakers while retaining an overall flat frequency and phase response. It is not so much adding a subwoofer, but more like adding an additional low-frequency way to the speakers. The result is remarkable, especially when reproducing appropriate acoustic instruments. The tight, accurate, perfectly controlled bass unveils every last detail down to 28 Hz.

Sub A125-M – Our Most Compact Subwoofer

The Sub A125-M was designed with two applications in mind: the typical subwoofer setup, and the bass extension setup. In a .1 stereo or surround system, the A125-M will deliver the summed low end while retaining the trademark PSI Audio precision. In a bass extension setup, one A125-M per speaker will extend the satellites’ frequency range to create outstandingly rich full-range systems with lots of power across the entire spectrum.

Sub A125-M – Who is it For?

Our low-frequency speakers are designed to perfectly complement our entire speaker range, making the A125-M the perfect addition to our smaller speakers A14-M, A17-M or A21-M.

Even with the larger systems, the A125-M can extend the low end and relax the main speakers, increasing overall performance. Basically, the A125-M is meant to support our monitor speakers when the bass needs more power and precision.
