The PSI Audio A17-M is an active 2-way nearfield monitor designed for professional production environments. In addition to its high-quality drivers and acoustically optimized enclosure, it's PSI Audio's proprietary analogue technologies – such as AOI and CPR – that give the A17-M its neutral, precise sound image. Particularly noteworthy are its extraordinarily accurate stereo imaging and transient response, as well as outstanding bass reproduction for a device of this size. Each frequency band is driven by its own Class A/B amplifier, with crossover occurring at 3.5kHz.
ALG, AOI, and CPR are three of the acoustic and technical innovations developed by PSI Audio – without them, the A17-M would have entirely different sonic characteristics. The term Acoustic Loud Guide (ALG) refers to the optimised waveguiding that ensures the uniform dispersion of sound coming from the handcrafted tweeter. The Adaptive Output Impedance system (AOI) dynamically adjusts the output impedance of the amplifiers depending on the frequency, counteracting driver overshoot – thus contributing to the A17-M's excellent transient response. Finally, by actively compensating for propagation delay and phase differences, the Compensated Phase Response system (CPR) is responsible for the monitor's consistent stereo image, with its precise localisation and three-dimensional spatial rendering.
The PSI Audio A17-M can do absolutely everything required of a pro-grade reference monitor in nearfield setups. With its fully analogue components, it delivers the highest possible sound precision for professional audio work. And for its compact size, the speaker's bottom end is incredibly generous: Even when it's not paired with a separate subwoofer, the A17-M provides very solid foundations for monitoring over short distances. In addition to use in conventional 2.0 and 2.1 stereo configurations, this pro-grade speaker is also well-suited for multichannel applications. And because each individual unit is manually calibrated in an anechoic chamber, every A17-M has identical acoustic characteristics – no exceptions.
PSI Audio, a brand under Relec SA, is based in Yverdon-les-Bains, Switzerland. The company was originally founded in 1977 by Alain Roux as Roux Electroacoustique, specialising in Hi-Fi speaker development. In 1988, the company was restructured as Relec SA, expanding into PA and studio markets while producing both proprietary models and OEM products for renowned brands like Studer (1992–2003). The PSI Audio brand launched in 2004, offering premium studio monitors for professional users. These products are known for their fully analogue circuit designs and meticulous Swiss craftsmanship, ensuring exceptional performance and reliability for audio professionals.
The PSI Audio A17-M is most at home in the field of music production. Its objective sound characteristics, including high transient fidelity and precise stereo imaging, make the speaker particularly well-suited to recording and mixing. The A17-M will reveal every last detail of a track, helping producers identify any weaknesses and allowing them to make confident decisions when applying creative or corrective tools – even when time's at a premium. For extended low-frequency reproduction, a pair of A17-M monitors combined with PSI Audio's A125-M subwoofer form a perfectly integrated speaker system with a cohesive, linear overall response.
