For Your Safety

Proper use
The speakers are designed for the playback of audio signals that are transmitted by an external amplifier via a speaker cable. Only use the speakers as described in this user manual. Any other use will be deemed as not in accordance with the instructions and may lead to damage of property or even persons. The manufacturer accepts no liability for damage caused by improper use. The speakers are intended for domestic use.
Explanation of terms
You will encounter the following signal terms in this user manual:
This signal term indicates a moderate risk, which, if not avoided, may result in death or severe injury.
This signal term indicates a low risk, which, if not avoided, may result in minor or moderate injury.
NOTICE This signal term warns you of potential damage.

Safety notes
This chapter contains general safety notes which you should always observe to protect yourself and third parties. Also observe the warning notes in each chapter of this user manual.
An unsuitable setup location may result in injury and damage.
­ If the speakers are not securely mounted, do not use them in vehicles, in unstable locations, on wobbly tripods or furniture, on underdimensioned brackets etc. The speakers may tip or fall over and cause injury to persons or be damaged themselves.
­ Place the speakers in such a way that they cannot be knocked down inadvertently and make sure that the cables do not pose a tripping hazard.
­ Do not place the speakers near heat sources (e.g. heaters, ovens, other heat generating equipment such as amplifiers etc.).
Children can become trapped in the plastic wrapping when playing and suffocate.
­ Do not allow children to play with the device or the plastic wrapping. There is a danger of suffocation.
­ Ensure that children do not remove small parts from the unit or take



them off of the unit (e.g. control knobs or plug adapters). They could swallow the parts and choke.
Extended listening at high volumes may lead to hearing loss. To avoid damage to health, avoid extended listening at high volumes.
­ When the volume is set high, always keep a certain distance and never hold your ears directly on the speaker.
­ If an amplifier is set to full volume, this may produce very high sound pressure. This may have psychological consequences and also cause physical injury. Children and pets are particularly at risk. Set the volume control of your amplifier to a low setting before you turn it on.
This product contains magnetic material.
­ If necessary, consult your physician and ask for effects on implants such as pacemakers or defibrillators.
If the speakers are subjected to warm temperatures after being cold ­ (e.g. after transport), condensation may occur inside of them.
­ In this case, wait at least 2 hours before you connect and activate the speakers.

Improper handling of the speakers may result in damage or fire.
­ Do not place open flames such as burning candles or similar on the speakers.
­ Ensure sufficient ventilation.
­ Do not expose the speakers to direct sunlight.
­ Only use the speakers in indoor areas.
­ Do not use the speakers in wet rooms and protect them against dripping or spraying water. Make sure that no vases or other liquidfilled objects are located on or near the speakers in order to prevent liquid from penetrating the housing.
If the amplifier is underdimensioned, the amplifier may end up in clipping operation at high volumes, which could destroy the tweeters.
­ Only connect your speakers to amplifiers, which suit the output of your speakers.
An overdimensioned amplifier can destroy the bass speakers due to excessive volume.
­ If the music playback sounds distorted, reduce the volume.

Unpacking and Setup

· Carefully open the boxes, take out the EPE foam parts and carefully lift the speakers out of the box without touching the diaphragms.
Due to differing customer requirements, the Ultima 20 speakers are shipped without speaker cables. You can find suitable cables in our webshop ( in the "Accessories" area.
­ Check that all items have been delivered and that nothing is damaged. If you find any damage, do not operate the device; instead contact our customer service department.
Location tips
­ Select a stable, level base.
­ Make sure that the environment is clean and free from dust.
­ Select a location away from heat sources and direct sunlight.
­ Lay the connector cords so that they do not pose a tripping hazard.
­ Do not place any heavy objects on the cables or the speakers.

Positioning the speakers
The following data concern an "ideal listening room", in which the listener sits in a central position at a sufficient distance in front of the speakers (see the graphic) and no objects (tables or the like) are located in between. Unfortunately, the room, furnishings or other circumstances do not always allow for optimum arrangement.
Modern amplifiers offer a variety of possibilities for electronically compensating losses associated with the arrangement. The following general rule applies: You can always experiment on what works best in your listening room in terms of sound and appearance based on our recommendations. Let your ears (and eyes) decide!



Use as front speakers

Use as rear speakers

left speaker

right speaker

Stereo triangle

The speakers should be situated to the left and right of the listener and if possible, form an equilateral triangle with the listener ­ the so-called stereo triangle (distance from the listener = distance between the speakers). The speakers should project sound straight into the room or be arranged slightly towards the listener.
For example, shelves or sideboards are very well suited as a setup location for the speakers.



The rear speakers are set up or hung to the side of or behind the listener at a height of 1.20 m to 2.10 m (see the grey areas in the graphic).
The ideal position is offset by approx. 20 degrees from the parallel position to the listener on the left and right side . It is generally recommended that the distance of the rear speakers to the hearer's place exceeds one metre. However, if you (need to) sit closer, please ensure that the front sides of the speakers is not directly facing you. Rather, the speakers must be angled towards the wall .
Alternatively, you can create a greater distance by placing the speakers higher than 1.20 m (e.g. also on the ceiling) or further away .

· ULTIMA 20 7

Wall mounting
Wall mounting is also possible. For this purpose appropriate holders are available in our webshop ( in the "Accessories" area. They are mounted using the M6 threaded hole located in the speaker base.
It also serves to fix corresponding speaker stands, which you can also purchase in our webshop.

Risk of tripping!
­ Lay the cables so that they do not pose a tripping hazard.
1. Switch your AV receiver or multichannel active subwoofer off.
2. Lay one speaker cable from your AV receiver or multi-channel active subwoofer to each speaker. Use a high-quality double wire speaker cable with marked strands for this. The cross-section should amount to at least 1.5 .

A connector terminal with two terminals is located on the back of each speaker; the speaker cable must be attached to them.
The terminals are each marked red (+) and black (-).



Make sure the polarity is correct!
­ Connect each of the like coloured terminals of your speakers and your amplifier with one another; otherwise the sound quality will suffer. To facilitate this, the individual single wires of the speaker cables are marked with different colours or shapes.

6. Connect the speaker cable to your AV receiver or multi-channel active subwoofer. You should be able to find corresponding notes in the user manual of your device.
Removing the protective grids
You can take the protective grids off of the speakers by carefully reaching behind the protective grids and slowly pulling them off to the front.
By removing the protective grid, especially high frequencies will sound clearer.
When putting the protective grids on, please make sure that the installation pins slide directly into the corresponding jacks on the speaker.

3. Split the single wire down by approx. 30 mm on both ends and remove approx. 10 mm of insulation each.
4. Twist the stripped wire ends so that no strands are protruding. Tin coating is not necessary.
5. Turn the connector terminal counterclockwise until loose. Run the stripped cable end into the now visible hole. Close the connector terminal by turning them clockwise. The cable has now been clamped in place.

Care and Cleaning

The veneered surfaces of our speakers have a protective surface coat so they no wood polish is necessary.
NOTICE External influences may damage or destroy the device.
­ If possible, only use plain water without any additives. In case of stubborn marks, a mild soap solution may be used.
­ Do not use caustic cleaning products, white spirit, thinners, petrol or similar under any circumstances. Such cleaning agents may damage the delicate surface of the housing.

· Ideally, you should remove dust or small amounts of dirt with a dry, smooth leather cloth.
· Rub off stubborn dirt with a damp cloth. Make sure that no liquid penetrates the speakers.
· Then immediately wipe the surfaces dry with a soft cloth without applying pressure.
