The PSI Audio Sub A125-M is a compact and precise subwoofer, engineered to fulfil the demanding requirements of professional audio environments. Its innovative acoustic design enables it to serve as a mono subwoofer or LFE in surround setups, or as a bass extension in stereo systems. Harmonising seamlessly with all speakers from PSI Audio's range, the A125-M delivers power with exceptional accuracy.

At the core of studio perfection, the A125-M excels in rendering the low frequencies where sound becomes a tangible, full-body experience. Beyond mere power, this subwoofer's precision creates a lasting impact, offering an exact reproduction of low tones. PSI Audio's commitment to unaltered, high-fidelity sound extends to the bass spectrum, ensuring a gripping experience to revolutionise your studio work. The A125-M eliminates the uncertainty in bass management, providing a trustworthy representation of the lower frequencies, thus enabling complete control and confidence in your production.

Redefining the concept of a subwoofer, the A125-M moves beyond the usual queries of depth and volume to prioritise precision. While standard subwoofers often produce a non-distinct rumble, the A125-M combines power and depth with punch, transients, speed, and accuracy, redefining it as a 'low-frequency precision monitor'.

This innovative approach continues in its design. The A125-M is engineered to extend the low end of PSI Audio loudspeakers while maintaining a flat frequency and phase response. It's not merely an addition of a subwoofer but an expansion of the low-frequency capabilities of the speakers. The result is astounding, particularly with acoustic instruments, revealing every nuance down to 28 Hz with tight, controlled bass.

The Sub A125-M's compact form factor suits typical subwoofer setups and bass extension configurations. A .1 stereo or surround system delivers summed low frequencies with PSI Audio's hallmark precision. Alternatively, paired with each satellite speaker, it extends its frequency range, creating rich, full-range systems with robust power across the spectrum.

Compatible with PSI Audio's entire speaker range, the A125-M is an ideal companion for smaller speakers like the A14-M, A17-M, or A21-M, and even enhances the performance of larger systems by extending the low end and easing the load on the main speakers.

Every unit of the A125-M is handcrafted in Switzerland with meticulous attention to detail. This manual manufacturing process allows for the fine-tuning of components, ensuring optimal performance and quality. From the selection of wood to the final paintwork, every cabinet is crafted with the utmost care, embodying PSI Audio's dedication to excellence in professional audio equipment.
