General Tips
Depending on the size and weight of your loudspeakers, it is a good idea for two people to unpack them. The
ideal way to do so is to stand the boxes upright so that the top of the loudspeaker is resting on the floor
(the boxes are marked accordingly) and you can easily attach the foot construction. Take out the accessory
packs, which are located in smaller boxes inside the main box. These packs contain the parts that you will
need in order to attach the loudspeaker feet. The spikes for both loudspeakers can normally be found in the
accessory pack of one of the two boxes (“Accessory Pack 1”). Please follow the instructions in the chapter
“Unpacking and Assembly“ to ensure the safe and correct installation of your loudspeakers.
The loudspeakers should reach a temperature that is approximately equivalent to room temperature before
you connect them to the HiFi system and/or operate them. This instruction predominately refers to the winter
months in case the loudspeakers were previously stored in a cold room.
Maintenance
Our loudspeakers are coated in high-quality veneers or high-gloss lacquers. You should avoid using chemical
cleaning agents because these can attack the loudspeaker surfaces and make them go matt. As a rule, a fine,
soft and damp cloth is all that you need to clean the surfaces. If a cleaning agent is required, use this to
dampen the cloth and do not directly apply it to the surface. It is best if you test the suitability of the
cleaning agent on a less visible part of the cabinet. The drivers do not normally need to be cleaned. Dust
particles fall off quickly when the loudspeakers are operated. You can, however, use a soft brush to lightly
brush over the surfaces of the drivers. When doing so, make sure you do not put any pressure on it. Please
never use any cleaning agents on the drivers. Do not expose the loudspeakers to direct sunlight. Anodised
surfaces are sensitive to acids and alkalis and to ultraviolet light and may fade.
The drivers in this loudspeaker use a unique mounting technique. Rather than directly mounting the drivers
onto the cabinet of the loudspeaker, the drill holes of the CARDEAS plus
+
contain special neoprene plugs.
These neoprene plugs tighten in the mounting hole when the screws are fitted, creating a permanently elastic
connection between the driver and the cabinet that reduces resonance. You do not need to tighten these
screws. Re-tightening the screws may damage the plugs and have a negative effect on the sound.
Burning in the Loudspeakers
The loudspeakers first reach their full sound potential after a specific burn-in period. We burn in the drivers
of the CARDEAS plus
+
at our factory prior to assembly, meaning that they normally only need a burn-in
period of a few hours at a normal room volume and with music that has a range of frequencies that is as
wide as possible, for example orchestral pieces. Recordings containing ’white or pink noise’ such as those
available on many so-called Test CDs are also ideal. For safety reasons, these pieces should never be played
at high volumes.
Stray Magnetic Fields
The magnetic field created by the individual driver magnets may to some extent have an effect outside of
the loudspeaker. This stray magnetic field may interfere with other devices, particularly televisions and
monitors with cathode ray tubes (not LCD or plasma televisions), for example by causing changes in colour
in the picture. We recommend that you place the loudspeakers approximately half a metre away from such
devices (and also from magnet tapes, video cassettes, credit cards with magnetic stripes, etc.).
Where possible, please retain the loudspeaker packaging. You can then securely transport your loudspeakers
if you move house.
