The pinnacle of current PSI Audio system development, the A25-M main / mid-field reference monitor features a staggering precision of /- 1.5 dB tolerance between 38Hz and 20KHz.
The tweeter unit is hand-crafted in-house in order to ensure performance and accuracy. These highly optimised features make the A25-M unique. A true reference speaker for stereo and surround sound applications where ultimate precision is required. The powerful tri-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 A25-M unprecedented impulse behavior – with excellent stereo imaging.
The crossover is also optimized for maximum phase coherence, which allows for a very broad horizontal and vertical ideal listening area. Tilting the mid-high range unit by 90° maintains the directivity accuracy when using the speaker horizontally. The A25-M’s 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 A25-M also makes ideal front speakers in a surround sound setup, or can be developed in to a more powerful system by adding the pair A225-M sub – thus providing an upgrade path and protecting your investment.
