Recommendations for use
The behaviour of Aria K2 936 loudspeakers depends on the acoustics in the listening room, on the correct
positioning of the loudspeakers within the room and on the position of the listener. It is possible to work
these elements together to correct or improve a desired effect.
Stereo perception is imprecise and poorly centred : try moving the loudspeakers closer to one another
and/or have them facing the listening point
Sound is harsh, aggressive : the acoustic in your listening room probably has too many reverberations.
Consider using sound softening (carpets, upholstered furniture, wall hangings, curtains, etc.) and sound
reflecting materials (furniture) to absorb or diffuse resonance.
Sound is "flat", "strangled": there are too many sound absorbent items in the room, the sound is soaked
up, it has no relief. Look for the best compromise between sound absorbing and sound reflecting materials
in your room.
In general terms, it is good to aim for the wall behind the loudspeakers being reflective for the sound to
develop correctly. The wall behind the listening position, on the other hand, is ideally sound absorbing
to avoid rear reflections "contaminating" the stereo image. Furniture can be judiciously placed near the
side walls of the room to diffuse sound waves and ensure certain frequency zones, particularly in the mid-
range, are not excited ("flutter echo" suppression).
Accessories
Aria K2 936 floorstanding speakers are fitted with spikes on their metal plinth. These can be adjusted
in height using the tool provided. After use, this tool is stored behind the loudspeaker protection grille
(fig. G, H).
Precautions for use
The TNF tweeter uses a relatively flexible Aluminum/Magnesium alloy, with a "shape memory" enabling it
to withstand the majority of small impacts in the home. Nevertheless, we recommend leaving the fabric
grilles in place to protect the dome. If the dome surface is marked this could have an impact on the
tweeter.
Cleaning instructions
The only maintenance required for the Aria K2 936 is dusting with a dry cloth. If the cabinet becomes
marked, we recommend simply using a damp cloth. The glass top-plate can be cleaned using a soft cloth
and a standard glass cleaning product.
Never use solvents, detergents, alcohol-based or corrosive products, scrapers or scourers to clean the
loudspeaker surface.
Keep the loudspeakers away from sources of heat.
Choice of amplifier
It is not an excess of amplifier power that can damage your loudspeakers and drivers but a lack of power.
Moreover, if the volume is turned too high, the amplifier saturates and generates parasite signals that may
destroy the tweeter.
The dynamic capacity and definition of Aria K2 936 loudspeakers are sufficient to show up the strengths
and weaknesses of whatever amplifier is connected. Your retailer will be able to guide your choice, to suit
your tastes and budget.
