Teufel products the warranty may be transferred to the
purchaser as long as the original proof of purchase is
also passed on to the purchaser.
Returns
Teufel provides the right to exchange or return within
eight weeks with refund of the purchase price paid.
Return of individual components sold as a package is
only possible if these components are also sold individually by Lautsprecher Teufel. In the case of the return of
one or more individual components the package price
reduction offered by Lautsprecher Teufel on all components in a package no longer applies. The amount
refunded to the customer for the components returned will
therefore only be the difference between the package
price and the purchase price of the individual parts. The
economic result for the customer is that it is as if he/she
had originally bought the remaining components at their
individual prices.
Further information on the subject of returns may be
found on the back of the returns form enclosed with the
order or online in the support area of our website www.
teufelaudio.com.
If you need to return your goods please do not act without fi rst speaking to Lautsprecher Teufel.
We can only process or accept your returns if you give
us prior notifi cation by telephone and discuss how to
proceed!

Unpacking and setup
Open the boxes carefully, take out the speakers in their
EPE packaging foam parts and carefully take the foam
parts off without touching the diaphragms.
Connector cable
Due to differing customer requirements, the
T 400 series is shipped without connector
cables. You can fi nd suitable cables in our webshop
(www.teufelaudio.com) in the “Accessories” area.
Check to be sure
Check that all items have been delivered and that noth-•
ing is damaged.
If the delivery is incomplete or you fi nd damage sus-•
tained in transit, do not operate the unit but contact our
service department (see page 3).
Location tips
Select a stable, level base.•
Make sure that the environment is clean and free from •
dust.
Avoid placing the unit close to sources of heat or in •
direct sunlight.
Arrange the connector cables so that they do not pose •
a trip hazard.
Do not place any heavy objects on the cables or the •
speakers.
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.
Left

Stereo triangle
Right

The following information concerns an “ideal listening
room”, where the listener sits in a central position at
an adequate distance in front of the speakers (see the
adjacent graphic) and there are no objects between the
listener and speakers (tables or the like). Unfortunately,
available space, furnishing or other circumstances may
not always allow for an optimum arrangement.
Modern amplifi ers offer a variety of possibilities for
electronically compensating losses associated with the
arrangement. The following generally 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) be the judge!
Removing the protective grids
You can remove the protective grids from the speakers by
carefully reaching behind the protective grid and slowly
pulling it off to the front.
When reattaching the grids, ensure that the installation
pins slide into the corresponding holes on the speaker.

Connecting
Connection variations
In addition to a standard connection, where every speak-
er column is connected to the amplifi er with a cable, you
can also choose the variants “Bi-Wiring” or “Bi-Amping”.
Standard connection
With this connection, the T 400 speakers are connected
like conventional speakers with one 2-core speaker cable
each. The contact bridges between the connector termi-
nals may not be removed in the process; you can connect
the cables accordingly to the top or bottom terminals.
Bi-Wiring
For this, the high and midrange speakers are connected
with one cable and the two low range speakers are con-
nected with a second cable. This allows you to reduce
distortion with very long cables.
Bi-Amping
For this, the high/midrange and low range speakers have
their own amplifi ers.
Connecting the cables
Danger
Danger of injury/damage!
Arrange the cables so that they do not pose a
trip hazard.
Make sure the polarity is correct!
Connect the like coloured terminals of your
speakers and amplifi er with one another.
Otherwise the sound quality will suffer. The individual
strips of the speaker cables are marked with different
colours or forms to facilitate this.
You only have to remove the 4.
contact bridges when using
Bi-Wiring or Bi-Amping: Turn
the binding posts counterclockwise until loose and then pull
out the contact bridges. The
top terminals lead to the high
range and midrange speakers,
the bottom terminals lead to the
low range speakers.
Split the core on 5.
both ends up to
approximately
30 mm and
remove approximately 10 mm
of the insulation
on each piece.
Twist the core so
that no wires are protruding.
Turn off your amplifi er.1.
Lay the speaker cable from your amplifi er to each 2.
of the speakers. This cable should be a high-quality
double-core speaker cable with marked wires. The
cross-section should amount to at least 2.5 mm
A connector terminal with four 3.
binding posts is located on the
back of each speaker. You can
connect the speaker cables using
banana plugs or directly. We
only describe the direct connection here. The terminals are each
marked red (+) and black (-).

.
Turn the binding post counter-6.
clockwise until loose. Run the
stripped cable into the hole
that is now visible. Turn the
post clockwise until closed. The
cable has now been clamped
in place.
Connect the other end of the 7.
speaker cables to your amplifi er. The operating instructions
of the appliance should contain
notes on this.

Care and cleaning
The veneered surfaces of our speakers have a protective
surface coat, which eliminates the need for wood polish.
You can best 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 using a soft •
cloth and without applying pressure.
Protecting the environment
Disposing of the unit
Used units must not be disposed of with household waste.
If the unit is no longer operational, every
consumer is required by law to dispose of
used devices separate from household waste,
Attention
e. g. at a collection point run by the communal authority borough. In this way, used devices can be recycled
and waste materials disposed of in an environmentally
friendly manner.
For this reason, electrical equipment is labelled with the
displayed symbol.
Risk of damage!
Using the wrong cleaning materials may dam-
age the delicate surface of the case.
If possible use only plain, lukewarm water with no •
cleaning products. In case of stubborn marks, a mild
soap solution may be used.
In no circumstances should caustic cleaning products, •
white spirit, thinners, petrol or similar be used for cleaning.
