Recommendations for use
The behaviour of the loudspeakers depends on the acoustics of the listening room, on the correct positioning
of the loudspeakers within the room, and on the position of the listener.
It is possible to tweak each of these parameters to obtain or improve a desired effect.
Stereo perception is imprecise and poorly centred: try moving the loudspeakers closer together and/or
have them facing the listening point:
The sound is harsh, aggressive: the acoustics of your listening room are probably too reverberant. Consider
using sound-absorbing materials (carpets, upholstered furniture, tapestries, curtains, etc.) and sound-
reflecting materials (furniture) to absorb or diffuse resonance.
The sound is "flat", strangled: there are too many sound-absorbing materials 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, aim to have a reflective wall behind the loudspeakers for the sound to develop correctly. The wall
behind the listening area, on the other hand, should ideally be 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 ranges are not excited, particularly in the midrange (suppression of flutter echoes).
Spikes
Spectral 40 floorstanding loudspeakers are equipped with decoupling spikes. These spikes give the
th
floorstanding loudspeakers very good stability, particularly on uneven floors. The height of the spikes supplied
can be adjusted to ensure the 4 spikes rest evenly on the floor to prevent any wobbling. Four spike pads are
also supplied to protect soft floors such as parquet, etc...
To fit the pads, tilt the loudspeaker slightly and place a pad underneath each spike, one by one.
We strongly recommend that two people do this together, paying particular attention when your
hands get near to the spikes, owing to the risk of injury.
Break-in period
The speaker drivers used in Spectral 40
certain time to adapt to operate at their best and to become acclimatised to the temperature and humidity
of the listening environment. This break-in period varies depending on the climate and may last a few
weeks. To reduce the break-in period, we recommend operating the loudspeakers for approximately twenty
consecutive hours. Once the loudspeakers' characteristics have totally stabilised, you will be able to enjoy
your Spectral 40 loudspeakers' performance to the full.

Special precautions
The only maintenance required for the Spectral 40
loudspeaker becomes dirty, we recommend simply cleaning it with a damp cloth.
Never use solvents, detergents, alcohol-based or corrosive products, scrapers or scourers to clean the
surface of a loudspeaker.
Keep the loudspeakers away from sources of heat.
