PSI A21-M, Active Studio Monitor, Black (per speaker) PSI-A21M-BLK

The Black PSI A21-M-BLK is a near & mid-field precision monitor. The A21-M is an active, 2-way, bi-amplified monitor featuing a broad frequency spectrum. The A21-M-BLK can be complemented by adding the A225-M sub and is also suited for use in a PSI A-Series surround sound system as front speakers.

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.
