PSI Audio A21-M (studio red)

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.
