Prio 520 is a slim two-way construction, which does not take any more room than a small bookshelf provides much more bass output.

Prio 520 was the first Amphion product to introduce the TAPS (Time Accurate Point Source) concept. TAPS ensures perfect integration of the drivers and creates a time-coherent point source multi-driver combination.

A low crossover point of 1600 Hz together with precise voice coil placement allows drivers to act like one big unit. The newly improved waveguide drastically improves the tweeter extention and purity further improving the the traits Paul Messenger noted in this review for Hifi Choice

"This speaker is capable of fine focus and very superior imaging, with good depth perspectives and precise soundstaging." 

Due to high sensitivity and carefully selected balance Prio 520 and acoustically identical center speaker 520 C can be used with a variety of signal chains with superb results. Openness and engaging presentation can be enjoyed even with relatively modest equipment. As Mr. Messanger said Prio 520 is: "particularly inviting for long listening."


U/D/D stands for Uniformly Directive Diffusion. By creating even dispersion the anomalies caused by wall, floor and ceiling reflections are minimized. This allows the listener to hear less of their room and more of their music.

"Optisch eher unscheinbar, entpuppt sich die Finnin als hochaudiophiles „Hörgerät“ für anspruchsvolle Musikliebhaber. Die Prio 520 ist problemlos in Wohnräume inte- grierbar und nimmt auch einen Platz etwas dichter an der Wand nicht übel. Dass sie in Sachen Tiefgang und Pegel begrenzt ist, fällt kaum ins Gewicht, denn hinsichtlich Geschlossenheit und Musikalität macht der Amphion zu diesem Preis keiner etwas vor."
