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.

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.

Sub A225-M – Who is it for?

Designed to complement our large three-way systems, the A225-M packs a lot of power to support full-range listening without compromise. It can also extend a smaller system, of course, or even mixed setups like in surround applications as the LFE. The A225-M is at home wherever low frequencies need to be monitored reliably, like in mixing, mastering and post-production.

Extend the low frequencies and add power

Ranging down to 56 Hz, the A14-M already impresses with a lot of transparent bass reproduction for its size. By adding one of our subwoofers, you can turn a pair of A14-M into a proper full-range system with all the clarity and precision you desire.
