The perfect low end in your studio

Given enough power, going low with a speaker is not too much of a challenge. Reproducing low frequencies with precision, however, is a different matter entirely. The PSI Audio Sub A225-M brings a whole new dimension of accuracy to the low end.

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 A225-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 real trick is to simultaneously provide a pure neutral processed signal and bypass all the obstacles on the road to obtain it.

PSI Audio staff challenged laws of physics and mechanical constraints. Engineers from the company PSI Audio mastered this art.”

Add control on your surround setup or on low frequencies

If you use a surround system or are working with several different speakers, our R&B – Router & Bass management System – could save you a lot of time.

R&B is an 8 in / 8 out transparent matrix that will fit into A225-M and help you selecting the speakers you are working with.

Please note that R&B is an option for the Sub A225-M and is not included as standard.

What our users say

The Sub A225 brings a relief, a natural depth to the A21, thus making the decomposition of the plans that make up an incredibly intuitive mix.
