Helium410

Helium520

Despite being small and easy to place Helium410 sounds fullbodied and works nicely without a subwoofer. Helium410 iscompact and easy to place, even as a surround speaker. Its
timeless appearance and variety of color options allow you toblend it with any decor.

Slim, elegant and easy to place Helium520 adapts to yourrequirements ­also aesthetically. It maybe be poised and pretty,
but packs a mighty punch.
Amphion Waveguide not only integrates the drivers, but also
provides a wide and evenly balanced listening area, so that you
can enjoy your music even while moving around in your home.

Helium510
Helium520C
Helium510 is a highly versatile loudspeaker. Due to wideand even dispersion Helium510 performs well in real world
placements, where traditional non-controlled speakers run intotrouble. Helium510’s clear, natural voice band is a joy. Especiallyas it keeps its intelligibility even at whisper-like late night listening
levels.

Helium410”The sound has impressive impact withimmediacy and warmth.”
Stephen Mejias, Stereophile Magazine

Midrange resolution and clarity of human voices are especially
important for center channel. The TAPS concept (Time Accurate
Point Source) allows drivers to act like one big unit.
Helium520C is electrically identical to Helium520 floorstanders
to ensure perfect integration between channels.
It also works well with Helium510.

Helium510”This is a well-built and exactly thought outspeaker, that has much to recommend it.”
”Beyond-its-class fidelity.”
Srajan Ebaen, www.6moons.com

Helium520”This is a truly exceptional and clever speaker,
offering a rare combination of warmth, neutrality,coherence and fine imaging.”
Paul Messenger, Hifi Choice
