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).
Break-in period
The speaker drivers used in Theva loudspeakers are complex mechanical components which require
a 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 Theva loudspeakers' performance to the full.
Special precautions
The only maintenance required for the Theva loudspeakers is dusting with a dry cloth. If your
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.
Choosing the right amplifier
It is not an excess of amplifier power that can damage your loudspeakers and speaker drivers but a lack of
power. Moreover, if the volume is turned up too high, the amplifier saturates and generates parasite signals
that may damage the tweeter. The dynamic capacity and definition of Theva loudspeakers are sufficient to
reveal the strengths and weaknesses of whatever amplifier is connected. Your retailer will be able to help
you choose the amplifier best suited to your tastes and budget.
Audio/video amplification
Please make sure your amplifier is Dolby Atmos® compatible.
Recommendations:
• If your amplifier is equipped with an auto-calibration function, make sure that your amplifier has the
latest firmware.
• If you configure the amplifier manually, we highly recommend:
- setting Dolby Atmos® speaker in "Small".
- doubling the distance of the Dolby Atmos® loudspeakers compared to the front speaker drivers.
- increasing the level until you obtain the desired result.
Conditions of warranty
All Focal loudspeakers are covered by warranty drawn up by the official Focal distributor in your country.
Your distributor can provide all details concerning the conditions of warranty. Warranty cover extends
at least to that granted by the legal warranty in force in the country where the original purchase invoice
was issued.
