PSI Audio – A25M Three-Way Active Monitors
Sound On Sound Magazine
by Phil Ward
Swiss company PSI combine traditional and modern design practices to deliver a monitor that is both powerful and extremely revealing.
Swiss monitor manufacturers PSI have made one previous appearance in the pages of Sound On Sound, back in July 2011. On that occasion, Hugh Robjohns was highly impressed by their A17M and A21M active nearfield monitors, so when the opportunity arose to try the company's most ambitious design, the three-way A25M, I didn't need asking twice. Having said that, I will admit to a moment's regret when I helped the delivery driver carry the two boxes down into my basement, because the first thing that's apparent about the A25Ms is their weight.
They are not only very heavy, at 28.4kg each, but have the kind of proportions that make a one-person lift of such a weight risky, and a two-person lift, well, just a little intimate. I'm always warm and welcoming to delivery drivers, but there are limits. The size and weight of the A25Ms mean they will probably not be considered for nearfield duties by the majority of potential users. At 590mm x 320mm x 380mm, they are too large and too heavy to stand on any meterbridge I've ever seen, and while wall-mounting with brackets might be an option, I'd want the brackets installed by somebody who truly knew what they were doing. And if the wall is not of the solid, brick-outhouse variety, forget it. Realistically, then, the A25Ms fall into the mid-field category — somewhere between main monitors and nearfields — and will, I suspect, most often be found perched on top of speaker stands away from any walls, which is how I used them in my room. However, before I jump the gun and start to describe how the A25Ms perform, there's a fair bit to write about their design, which is an intriguing mix of the traditional and the unusual.
