Helium510, Bookshelf loudspeaker.

  • Bookshelf speakers that deliver unprecedented levels of sonic excellence and aural refinement.
  • Performance that matches its appearance, it is versatile and able to work with modest systems.
  • Characteristic Nordic design that translates into a clean, contemporary, timeless look.
  • Port plugs for an almost-sealed bass alignment to sonically adapt to different environments.


Helium510 bookshelf loudspeakers are the optimum price/quality solution for any home audio environment. Being a simple 2-channel setup for listening to music, or watching television, or 2.1 and 5.1 home theater systems for a complete movie experience, these highly versatile bookshelves fit perfectly. In addition to their flexibility in applications, Helium510 speakers are highly adaptable to your interior design, offering a multitude of colour options.

Helium510 loudspeakers employ custom Uniformly Directive Diffusion (U|D|D) technology which delivers a wide and even sound dispersion. This allows home audio speakers to perform excellently in a real-world placement where traditional, non-controlled speakers run into trouble. You can freely position Helium510 loudspeakers on a bookshelf or TV cabinet, and the controlled dispersion will still maintain the imaging and midrange clarity.

The signature Amphion waveguide integrates the drivers and provides a wide and evenly balanced listening field. In this way, the listening “sweet spot” is not selfishly located in a single point but widely spread so that you can enjoy your music even while moving around the room. A natural-sounding cohesive voice-band, and an extremely high level of speech clarity – even at very low listening levels – makes Helium510 a perfect partner for TV or background music.

Thease bookshelf loudspeakers deliver an unprecedented level of upper-midrange|treble refinement. They provide resolution and linearity that exceed what is common at this price-point in home audio loudspeakers. The extent of sound clarity and emotional enjoyment Helium510 speakers draw from even to a simple stereo system to home theater setup is second-to-none.
