Product Usage Instructions

Speaker Placement

The acoustic center-point of the speakers should be positioned between the end of the waveguide and the driver for single-woofer products, or at the tweeter center for two-woofer products.

To achieve correct stereo imaging, avoid placing the speakers too far apart. Use a vocal track with the singer in the center to adjust the speaker positioning.
Move the speakers wider apart to create a hole in the middle of the soundstage, then bring them closer until the channels integrate.

For depth information and optimal sound tuning, aim a direct line from the acoustic center-point to outside your shoulder line and adjust based on your preference.
Remember that a higher treble is directive and may impact the upper-midrange audio quality.

If needed, small wedges at the front or back edges of the speaker can help align the acoustic center to the listener’s ear for improved sound quality.

Wall/Ceiling Brackets

The Helium speakers are compatible with wall and ceiling brackets for versatile mounting options in various applications.
Ensure proper installation according to the provided guidelines for optimal performance.

Helium

Story Superb sound in any space

Helium is your first step on the road to a truly rewarding audio experience. Whether you’re listening to music, using streaming services, or watching a movie with family or friends, the clear, natural sound quality brings it all to life.

Regardless of where a Helium speaker is placed in the room, its controlled dispersion delivers pleasing, neutral audio – even at low volumes.
Helium speakers are available in Full White, Standard White, Black and Walnut veneer.
Grids are available in the RAL colours of your choice.

Speaker placement

Acoustic centre-point of the speakers
- This is either between the end of the waveguide and driver (single-woofer product) or tweeter centre (two-woofer product).
Phantom Centre
- For correct stereo imaging, do not place speakers too far apart. Use a vocal track where the singer is in the centre. Move speakers wider apart to hear the “hole” developing in the middle of the soundstage, then move them closer until channels integrate.
3D | Depth Information
- Start by aiming a direct line from the acoustic centre-point to outside your shoulder line. Then, “fine-tune” the sound to your liking. Note that the highest treble is always directive.
- Adding higher treble may smooth the audio in the upper-midrange.
Tilting – If Needed
- Small wedges at either the front or back edges of the speaker help to align/aim the acoustic centre to the listener’s ear. It is not overly critical but helps achieve the required sound.

Technologies

What is a Waveguide?

Waveguide: A generic term to describe a structure that directs sound waves, with minimal loss of energy, by restricting their expansion to one or two dimensions.

It helps create a wide, even sweet spot – though the highest treble is always directive.
It solves cabinet diffraction issues, aligns drivers, and makes dispersion-patterns between drivers more even across a wide frequency-band.
Amphion’s proprietary waveguide: Amphion is a frontrunner in waveguide technology and is widely recognised for its use of tweeter waveguides in front of the driver to control directionality – incorporating a technology called U/D/D (Uniformly Directive Diffusion).

Perfecting driver integration: The result is purer, more natural sound that is less interrupted by room acoustics, and helps speakers deliver clarity and naturalness – even when placed close to boundaries eg. walls, bookshelves, desktops, or highly-reflective surfaces. It creates a large, broad sweet spot suitable for busy modern living, where one cannot always sit in the sweet spot.

Time-adjusted drivers

All products use time-adjusted drivers and a 1600 Hz tweeter crossover.

This leads to point-source-like behavior and seamless driver integration.
Rock-solid “phantom” centre, lifelike 3D imaging, and an extremely wide and deep sweet spot are characteristic of all Amphion products.

Instructions

Care

Cleaning

When setting or repositioning speakers, wear soft cotton gloves.
To clean it, use a soft cotton or microfiber cloth. Do not use excess rubbing force.

Use water or CIF Multi-surface Window Cleaner (e.g. JIF, HANDY ANDY, VIM, VISS).
Spray cleaner onto the cloth first, rather than directly onto the cabinet.
Test-clean a small area on the back or under the cabinet to check the surface reaction.

When cleaning the walnut finish, wipe in the direction of the wood grain.

Individual support

Typically, a wide variety of factors influence loudspeakers’ performance. Please contact your local Amphion dealer or sales representative for specification, connectivity and positioning recommendations for your specific system.

For more information, you can also be in touch with Amphion headquarters.
