- After any repairs or an intervention on the device, ask the technician to test the equipment in order to check that the product works correctly and is safe.
- The device must not be mounted to a wall or ceiling unless intended by the manufacturer.
- In order to avoid damaging your hearing, do not listen to speakers at high volumes for extended periods of time. Listening to speakers at high volumes can cause damage to the user’s ears and may lead to hearing problems (temporary or permanent deafness, buzzing in the ears, tinnitus, hyperacusis). Exposure to excessive volumes (over 85dB) for more than one hour can cause irreparable damage to your hearing.
-
- Your loudspeakers use a tweeter with an inverted dome made from pure beryllium, a substance that is harmless in solid form. However, given its nature, certain precautions should be taken to avoid exposure to unnecessary risks:
- The beryllium dome must never come into contact with abrasive materials.
- If the beryllium dome is damaged in any way, use the protective adhesive strip supplied to cover the entire surface area of the dome, as soon as possible. You will find the adhesive strip in the plastic packet containing the leaflet for the tweeter with an inverted dome made from pure beryllium. Contact the retailer to have the tweeter dismantled and replaced by trained personnel at the distributor.
- If the dome is broken, any beryllium particles should be carefully collected using sticky tape and then placed in a hermetically sealed plastic bag and sent back to the retailer along with the loudspeaker. For more information, please refer to the safe use manual in the box. You can also address your questions directly to: beryllium@focal.com
Connections
Kanta 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.
Positioning
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 optimize their performance and to
guarantee 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 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. C). 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
Optimization
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).
Spikes
Kanta floorstanding loudspeakers are equipped with decoupling spikes. These
spikes give the 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.
Silicone pads (Kanta N° 1 , Kanta Center)
Kanta N°1 bookshelf and center speakers include silicone pads to protect the
bottom of the speakers. To place the speakers on a shelf or a furniture,
please stick the silicone pads before use
Securing the Kanta N°1 bookshelf loudspeaker to the stand The Kanta N° 1
loudspeaker can be secured to its stand using the screws supplied Make sure
the Kanta No. 1 loudspeaker is stable while it is being assembled on the
stand to prevent it from falling off. The speaker must be firmly secured to
the stand (screws properly tightened).
Foam Bung for Bass Tuning (Kanta N°1)
This foam bung allows you to make some fine adjustments to the bass
performance of your loudspeakers. The Kanta N°1 loudspeaker has been designed
to reproduce deep bass in an even manner for a «free space» position. If you
position your loudspeakers close to a wall, bass frequencies are further
enhanced. Similarly, some rooms have an acoustic that exaggerates low bass.
The foam bung allows you to reduce the amount of energy from the port tube to
reduce bass levels and improve damping in such situations. It is advised that
you use the foam bung for both loudspeakers. To do so, insert the foam bung
into the port tube as shown in Figure I.
Break-in period
The speaker drivers used in Kanta 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 Kanta loudspeakers’ performance to the full.
Special precautions
The only maintenance required for the Kanta loudspeakers is dusting with a dry
cloth. If you 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.
Kanta Center loudspeaker positioning
The Kanta Center loudspeaker must be placed within close range of the screen
for realistic dialogue reproduction. If a standard projection screen is used,
the center unit must be placed right under the screen for optimal performance.
If a perforated, acoustically transparent screen is used, the center unit can
be placed behind, at the lower half of the screen.
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 Kanta 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.
