A21-M

“Of particular note though is the remarkable step response, which is presumably helped by PSI Audio’s “Compensated Phase Response (CPR) system”. This accurate time response is very rare in this type of speaker but here, PSI Audio has proven that it is possible.”

– Keith Holland from Resolution Magazine, UK

Product Description

The A21-M high power near / mid-field precision monitor covers a broad frequency spectrum, allowing the user to be in full control of their audio production. Its unique and highly optimised assets make it perfect for near, mid-field and surround sound applications where ultimate precision is required.

The powerful bi-amplified output stages features the unique “AOI” output stages and has a protection circuit, which can be monitored via the red LED on the front panel.
The active crossover, with integrated “CPR”, gives the A21-M unprecedented impulse behavior – with excellent stereo imaging. The crossover is also optimized for maximum phase coherence, projecting a wide horizontal and vertical ideal listening area.

The electronics are housed in a unit mechanically isolated from the speaker cabinet to avoid resonance at high sound pressure levels.

Designed to work in harmony with the full range of A series monitors the A21-M also makes ideal front speakers in a surround sound setup, or can be developed in to a more powerful system by adding the A225-M sub – thus protecting your investment.
