Description

If you want to enjoy music with a sense of presence at home without spending a fortune, then Helium520 floorstanding speakers are the right choice. They provide open and natural sound with a warm tone and are the optimal solution in terms of price/quality for any home environment. The Helium520 speakers are known for their honest sound, revealing fine details while still handling imperfect source material.

Features:

  • Floorstanding, passive phase-inverted type speaker system
  • 25mm titanium tweeter and two 133mm paper woofers
  • Sensitivity: 90 dB
  • Great as front speakers for a home theater system
  • Natural sound capable of conveying microdynamics - even the quietest moments in a composition won't be hidden from the listener
  • Uniform Directivity Diffusion (U|D|D) technology for even sound distribution in space
  • Handcrafted cabinets in Finland with many color options

Technologies

The Helium520 utilizes Uniform Directivity Diffusion (U|D|D) technology, providing wide and even sound distribution in space. The directivity diagram resulting from U|D|D has the shape of a narrow cardioid. Therefore, the speakers can be placed close to the wall without fearing unpleasant consequences. The U|D|D technology is implemented through the arrangement of drivers, crossover design, and carefully calculated waveguide with the tweeter.

Speaker design

The 13cm woofers with paper diffusers are connected in parallel, working completely synchronously without timing or phase errors. Hence, the Helium 520 model is a two-way speaker. The tweeters, like all Amphion speakers, feature a 1-inch titanium dome with measures taken to eliminate peak resonances.

Design

The slim, elegant, and easy-to-install Helium520 speakers adapt to your acoustic and aesthetic requirements. They come in various colors, making it easy to fit them into your home interior. The cabinets are handcrafted and meticulously finished at the Finnish factory. Whether it's your TV system in the living room or Hi-Fi system in your bedroom, the Helium520 speakers always deliver a high level of sound satisfaction.

While the Helium520 floorstanding speakers may appear sleek and sophisticated, they possess a powerful attack. They are truly an exceptional model, offering a rare combination of warmth, neutrality, and excellent sound imaging. Their advanced acoustic design, high-quality components, and low crossover point allow for enjoying remarkable mid-frequency resolution that remains stable even at low volumes.
