SOUND QUALITY PERFORMANCE 92/100
Bass
92/100
Manufacturer specs show a 240 mm (9.4") woofer and a -6 dB low-frequency limit of 34 Hz, which implies deep and controlled extension for a stand-mount/large bookshelf monitor. Given the driver size and ported/vent info not stated, the 34 Hz bandwidth and high SPL capacity justify an above‑excellent 'for its size' bass rating.
Mid
92/100
Three-way design with a dedicated mid driver (172 mm / 6.8") and reported SPL tolerances of ±1.5 dB indicate very accurate, well-controlled midrange reproduction. Specs (crossover at 620 Hz and tight tolerances) point to authoritative timbre and vocal presence suitable for critical studio work.
Treble
91/100
27 mm (1.06") tweeter and a -6 dB high-frequency limit of 23 kHz support extended, detailed treble. Dispersion spec (85 x 40 deg) and phase tolerances imply refined high‑frequency behavior with minimal harshness when used in a professional nearfield setup.
Soundstage Imaging
90/100
Three-way architecture, controlled dispersion (85° horizontal) and phase tolerances (±45 deg) point to precise image focus, good depth and stable staging in typical studio placement. The monitor's dimensional and driver layout favor coherent imaging for mixing and critical listening.
Dynamics
93/100
Generous amplifier power allocation (310 + 120 + 55 W) combined with high max SPL figures (continuous 108 dB; peak short-term 111 dB; peak max 122 dB) indicate excellent macro and micro dynamic capability and headroom for demanding material.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
92/100
Substantial net weight (18 kg) and professional-grade specifications (XLR input, 5+1 year warranty) suggest robust construction and studio-focused engineering. Tight SPL/phase tolerances also imply careful calibration and quality control in design and crossover implementation.
Features Connectivity
86/100
Balanced XLR input (1 x XLR F / 3P) is standard for pro studio use and ideal for noise‑free connections; lack of additional digital/USB or consumer wireless I/O keeps the interface straightforward but limited. Score reflects professional connectivity but not broad consumer-feature breadth.
Value for Money
82/100
Price was not provided; the A23-M's pro-grade three-way design, deep extension and high SPL capability indicate a premium positioning. Without explicit pricing or comparative review language, the unit appears to offer strong performance but likely at a higher-than-consumer price, so value is rated conservatively.

“Swiss speaker gurus PSI Audio have never failed to impress us with their technical innovations, and their latest model is no exception!
The natural details of female voices and higher‑pitched acoustic instruments, if they have survived the tracking and mixing processes, are reproduced spectacularly. And if they haven’t survived the tracking and mixing processes, the problems are obviously revealed.
