Overview of PSI Audio A21-M

The PSI Audio A21-M is a high-precision, active studio monitor designed for critical listening applications in both nearfield and midfield settings. Known for its powerful output and transparent sound reproduction, the A21-M delivers an extensive frequency range from 38 Hz to 23 kHz, capturing detailed lows, mids, and highs for accurate mixes. It features PSI’s proprietary analog technologies like Compensated Phase Response (CPR), which ensures phase coherence, and Adaptive Output Impedance (AOI) to minimize distortion. Each monitor has Class G/H amplifiers that provide 120W to the woofer and 50W to the tweeter, resulting in a max SPL of 108 dB. Built for professional studios, the A21-M's bass reflex design and room-friendly roll-off adjustments make it versatile for various setups. However, its premium price and precision features are typically targeted at professional audio environments rather than casual or home studios.
