Description

If you want to enjoy music with a presence effect at home without spending a fortune, then Helium520 floor-standing speakers are your choice. They provide open and natural sound with a warm tone and are the optimal solution in terms of price/quality for any home setting. Helium520 speakers are known for their honest sound, revealing fine details and handling imperfect source material.

Features:

  • Floor standing, passive phase inverter type acoustic system;
  • 25mm titanium tweeter and two 133mm paper woofers;
  • Sensitivity: 90 dB;
  • A good solution as front speakers for a home theater;
  • Natural sound and capable of excellently conveying microdynamics - even the quietest moments in a composition won't go unnoticed by the listener;
  • Uniformly Directed Diffusion (U|D|D) technology for even sound propagation in space;
  • Cabinets are handmade in Finland and come in various finishes.

Technologies:

Helium520 uses Uniformly Directed Diffusion (U|D|D) technology, providing wide and even sound propagation in space. The radiation pattern resulting from U|D|D has the shape of a narrow cardioid. Accordingly, the speakers can be placed quite close to the wall without fear of unpleasant consequences. The U|D|D technology is achieved through the positioning of drivers, crossover construction, and a carefully calculated waveguide with the tweeter installed.

Speaker Design:

The 13-centimeter woofers with paper diffusers are connected in parallel, so they work absolutely synchronously without temporal and phase errors. Therefore, the Helium 520 model is two-way. The tweeters here, like throughout the Amphion acoustics, have a one-inch titanium dome. Measures have been taken in its design to eliminate peak resonances.

Design:

Slim, elegant, and easy to install, the Helium520 speakers adapt to your acoustic and aesthetic requirements. They are available in various colors, making it easy to integrate them into your home décor. The cabinets are handmade in a Finnish factory and meticulously finished. Whether in your living room TV system or Hi-Fi system in your bedroom, Helium520 speakers always bring high pleasure from the sound.

Helium520 floor-standing speakers may appear sleek and refined, but they have a powerful attack. This is truly an exceptional model, offering a rare combination of warmth, neutrality, and excellent sound image. Their advanced acoustic design, high-quality components, and low crossover point allow for enjoying remarkable mid-frequency resolution, which remains stable even at low volumes.

Package includes:

  • Floor standing speakers - 2 pcs;
  • Documentation.
