Thank you for purchasing a Focal product. Welcome to our High-Fidelity world. Innovation, tradition, excellence and pleasure are our values; our one and only aim is to bring you a sound that is rich, pure and true. To get the most out of your product, we recommend that you read the instructions in this booklet, then store it in a safe place to refer to in the future.
Handling (fig.A)
Theva N°3-D loudspeakers weigh more than 20kg. We strongly advise having 2
people lift them during unpacking and installation.
Theva loudspeakers have sharp corners. Take care not to injure yourself when
handling your loudspeakers.
Fixing the base (fig.B)
Align the base opposite the fixing holes, position the 4 screws supplied and
tighten them using the Allen-key provided. Make sure the base is the right way
up (upper part at the front of the loudspeaker).
Then simply attach the rubber feet or spikes depending on the type of floor
your loudspeaker will stand on. For hard floors, we recommend using the rubber
feet.
If installing your loudspeaker on carpet, using the spikes will provide
greater stability.
Grilles (fig.C)
Theva loudspeakers are supplied with grilles to protect the speaker drivers.
They are easy to fit or remove thanks to their magnetic attachment system.
We advise removing them when you are listening to music to get the best
performance from your loudspeakers.
Dolby Atmos® (fig.D)
Your Theva N°3-D loudspeakers supports Dolby Atmos®. The loudspeaker has a
speaker on top, facing upwards, to use ceiling reflections to achieve Dolby
Atmos® effects. Dolby Atmos® technology offers 3D sound, integrating the
vertical dimension, i.e. the propagation of sound from a new source of sound
emission: the ceiling. This new dimension brings precision and realism to a
multi-channel sound experience worthy of home-theater (fig. D).
Connections (fig.E)
Theva connectors provide reliable, multi-purpose contacts for stripped cables
(up to 4mm diameter), fork terminals or banana connectors. It is imperative to
respect the connector polarity of both the loudspeaker and the amplifier. The
connector marked “+” must be connected to the positive output on the amplifier
and the connector marked “-” must be connected to the negative terminal .
Stereo image and bass perception would be seriously compromised if these
conditions are not respected. Choose good quality cables with a cross-section
appropriate to their length: your retailer will be able to advise you.
Dolby Atmos® connections (fig.E)
Be sure to observe the connectors indicated on the back of the speaker. The
top connector corresponds to the speaker situated on top of the loudspeaker,
which reproduces Dolby Atmos® effects. The bottom connector refers to the
speakers on the front of the loudspeaker (fig. E).
Positioning (fig.F,G,I,J)
These loudspeakers have been designed to deliver the most faithful
reproduction of all kinds of music or home cinema programmes. Nonetheless, we
recommend following these simple rules to optimise their performance and to
warranty good tonal balance and a realistic sound image.
The loudspeakers should be positioned symmetrically, facing the listening
area, ideally forming an equilateral triangle with it. However, these
distances may be adjusted to find the ideal compromise according to the design
of your interior (fig. F).
The loudspeakers should be positioned at the same height, in the same
horizontal plane. Ideally, the tweeter should be positioned at the same height
as the listener’s ears in the usual listening position (fig. G). Do not
position your loudspeakers too close to a corner of the room and do not place
them too close to a wall. This will induce some unwanted room resonance and
artificially increase bass response. On the other hand, if the bass level is
considered to be insufficient, you could try moving the loudspeakers nearer a
wall to re-balance the bass level (fig. J).
For a home cinema setup, please refer to the figure I for the placement of
your loudspeakers (fig. I)
CAUTION
With a Dolby Atmos® installation, it is advised not to have any obstacles
(shelf, lamp, etc.) less than 3 feet (1m) above the Theva N°3-D loudspeaker
that could impede the reflection of Dolby Atmos® sound off the ceiling.
Optimisation (fig.H)
For perfectionists, here is a formula for optimal positioning:
If A is the distance from the centre of the woofer to the nearest floor or
wall, B is the distance to the next closest floor or wall, and C is the
greatest distance (A < B < C), the equation B2 = AC defines the ideal
loudspeaker position.
Example
If the centre of the woofer is 20″ (50cm) away from the rear wall (A) and 24″
(60cm) above the floor (B), then the side wall will be ideally 28″ (72cm) away
[C = B2 ⁄ A = 28″ (72cm)].
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).
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.
