PSI Audio Sub A125-M – a compact, high-precision studio subwoofer featuring an 8.3" woofer, frequency response from 28 Hz to 90 Hz, a 340 W peak G/H-class amplifier, and a fully analog signal path with no DSP.
The Sub A125-M is PSI Audio’s most compact subwoofer, delivering exceptional accuracy and control across the low-frequency spectrum. Designed for both LFE applications in surround setups and bass extension in stereo systems, it integrates seamlessly with the entire PSI Audio monitor range. Each unit is individually calibrated in an anechoic chamber to ensure precise frequency and phase response, providing reliable low-end reproduction for mixing, mastering, and critical listening.
Built entirely without DSP and handcrafted in Switzerland, the A125-M offers the brand’s signature fidelity and transparency, now extended into the sub-bass region. Its efficient G/H-class amplifier ensures power and detail in a compact enclosure that fits any studio layout. This is not just a subwoofer—it's a low-frequency precision monitor that reveals every nuance down to 28 Hz, transforming your monitoring setup into a full-range system with maximum confidence and sonic integrity.
