PSI Audio

  • Mid-field / Main Reference Monitor
  • 10.2″ Woofer, 5.6″ Mid, and 3.9″ Tweeter
  • Class-G Amplifier
  • Tri-Amp: 170W + 80W +50W
  • Freq Response: 28 Hz to 23 kHz (-6 dB)

Audio engineers and professional studios in search of a high-powered studio reference monitor will be impressed with the single, black PSI Audio A25-M, the company’s flagship main and mid-field studio reference monitor designed to be tonally balanced; with high-resolution detail and an efficient transient response for precision accuracy in surround setups and stereo studio monitoring applications. The tri-amplifier delivers 170W to the 10.2″ woofer, 80W to the mid-driver, and 50W to the 3.9″ tweeter, which combine to provide a frequency tolerance of 38 Hz to 20 kHz (+1.3 dB) at an SPL of 124 dB per pair. The tweeter is handcrafted in-house to ensure performance and accuracy.

The amplifier output also features AOI output stages and includes a protection circuit, which can be monitored via the red LED on the front panel. The active crossover with integrated CPR delivers an impulse behavior with accurate stereo imaging. The crossover is also optimized for maximum phase coherence, projecting a wide horizontal and vertical listening area. The electronics are housed in a unit that is mechanically isolated from the speaker cabinet to avoid resonance at high sound-pressure levels.

The rear panel offers a balanced XLR input and features a volume control and a roll-off control for optimizing the low frequencies for standalone use or when using an optional subwoofer. The mid-high section can be turned 90°, allowing for the speaker to be placed in a horizontal position, while maintaining proper dispersion. The PSI Audio A25-M includes a power cord, anti-slippage stickers, and an individual frequency-response diagram.

Adaptive Output Impedance (AOI)
The AOI is made up of a system that detects the movement of the membrane and the coil as well as a filtered counteraction. This is then tuned to achieve the ideal dampening rate for each frequency.

Acoustic Load Guide (ALG)
The ALG is used in all regular 2-way and 3-way PSI Audio speakers. The shape and dimensions of the waveguide used in PSI Audio’s custom tweeter is specially designed to optimize directivity as well as maximize sound-pressure level and extend bandwidth.

Compensated Phase Response (CPR)
The CPR system is made up of several all-pass filters, each acting in a specific range. Combined, they create a compensated phase response, which provides a constant group delay that is kept to the bare minimum through the entirely analog technology.

Phantom Standby Control (PSC)
The PSC technology enables remote activation and deactivation of the standby mode of your loudspeakers via the signal cable.
