PSI Audio A23-M – Compact Three Way Studio Monitor Perfection
The A23-M is a precision engineered three way active studio monitor that blends advanced analogue technology with a bespoke mid range driver for unmatched accuracy in professional audio production. Handcrafted in Switzerland with meticulous attention to detail, each unit is individually calibrated in an anechoic chamber and delivered with its own frequency response certificate.
With tri powered Class G/H amplifiers for the woofer and mid range, and Class A/B for the tweeter, the A23-M delivers robust performance: 310 W + 120 W + 55 W of power, a wide bandwidth from 34 Hz to 23 kHz, and peak sound pressure levels reaching 122 dB at one metre. The flat frequency and phase response ensure that what you hear is exactly what is in the mix, making the A23-M ideal for mixing, mastering, broadcasting, post production, or high end home listening.
The high precision handmade tweeter and mid range driver are complemented by a rotatable tweeter mid unit (swivel 90°) allowing flexible studio placement while preserving stereo imaging. Its compact dimensions (280 × 500 × 340 mm) and weight (18 kg) make it a practical choice for mid field monitoring in studios with listening distances from 1.2 to 3.5 metres.
Whether used as a standalone reference or paired with a subwoofer (such as the optional Sub A125-M or Sub A225-M) to extend low end performance, the A23-M maintains the signature PSI Audio clarity, transparency and stereo precision that professionals demand. The craftsmanship is reflected not only in sound but also in design: each cabinet is built from premium wood and available in Studio Red, Metal Black or Pure White finishes.
For audio professionals seeking true accuracy in a compact three way monitor, the PSI Audio A23-M stands out as a reference class solution that does not compromise.
