PSI Audio | Sub A125-M

Their subwoofers are designed to seamlessly extend the frequency of any PSI Audio monitor. This means that the monitors, with roll- off, and subwoofers are perfectly in phase and that the total frequency response is flat.The SPL of the A125-M is adapted to work with PSI Audio’s smaller monitors such as A14-M, A17-M (see photo) or even the A21-M. Two of them will also work in stereo with the larger models such as A21-M and A25-M.
