Amphion Prio 520

The Amphion Helium 520 is a slim floor-standing speaker with a traditional design. The exact dimensions are 1040x160x215 millimeters. No rounded corners or tapered cabinet for this Fin. The Helium 520 is equipped with two 5.25 inch mid/low drivers with a paper cone. The tweeter is a 1 inch titanium dome specimen and is located between the two woofers, in a so-called D'Appolito arrangement. Characteristic of Amphion speakers is that the tweeter is placed in a kind of horn to create as uniform a radiation pattern as possible to the front. They call this the U/D/D themselves, an abbreviation for the Uniformly Directive Diffusion principle. This means that reflections from walls and ceiling are kept to a minimum and the speakers are easier to place in the room. All units are individually protected by a non-removable metal grille.
