This is either between the end of the waveguide and driver (single-woofer
product) or tweeter centre (two-woofer product).
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.
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 highest treble
is always directive. Adding higher treble may actually smoothen the audio in
the upper-midrange.
Small wedges at either front or back edges of speaker help to align/aim the
acoustic centre to the listeners ear. It is not overly critical but helps achieve the
required sound.

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

When setting or re-positioning speakers, wear soft cotton gloves.
To clean, 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 surface reaction.
When cleaning the walnut-finish, wipe in the direction of the wood-grain.
Individual support
Cleaning Amphion loudspeakers come with grids of your colour of choice. Do you want
to change the looks later on?
Just pick another colour and replace the grids.
Care
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.
