 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, the R+B - Router and 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.
A subwoofer for the whole range
 The Sub A225-M is the perfect addition to any PSI Audio speaker setup. No matter if you are working with the compact A17-M or the large A25-M, the A225-M will seamlessly integrate with all our monitors. Simply engage the bass roll-off on the satellites and enjoy a full-range system that extends down to 24 Hz with all the linearity in frequency and phase that you are used to from your monitor speakers.
