Two dipole speakers for expanding your Theater 500 Surround Set into a 7.1 set.

Dipole speakers send sound forwards as well as backwards in a phase-shifted form. This type of sound dispersion ensures atmospheric levels of room reflections, an effect very similar to that achieved in cinemas by multiple speakers. Only Teufel offers such elaborate but effective speaker technology in this price class. For gaming, the dipoles can be transformed into direct sound transducers for the precise localisation of opponents. Integrated keyhole brackets make it easy to mount the speakers to the wall.

Dipole speakers for an authentic cinema atmosphere

Dipole speakers are specially designed for use as rear speakers in a surround system. Instead of radiating sound directly towards the listener, dipoles disperse phase-shifted sound in two directions. The listener perceives a diffuse atmosphere that fills the room, the same effect large cinemas achieve with a large number of speakers arranged behind the viewers.
For gamers, the Theater 500 Surround’s dipoles can be switched off for better localisation of objects and opponents. Each T 500 DR 16 dipole comes with integrated keyhole brackets for easy wall mounting.

Specifications

Dipole Speaker T 500 DR 16
Dipole Speaker T 500 DR 16
The T 500 Ds are equipped with double drivers - one tweeter and one bass-midrange driver per side are phase-shifted. Such a dipole concept creates a diffused spatial representation and a gripping atmosphere. For gaming, the dipoles can be switched to direct emitters for perfect placement of your opponents.

Help regarding this product
Can I also put the dipoles on stands?
It is possible, but we don't sell any bases that meet the minimum recommended height of 1.50 metres. Stability at this height can only be guaranteed if the base plate is very big. A base of around 1 x 1 metre isn't going to look very attractive.

Perhaps your joiner will be able to make you something that will match your room. You should also make sure that the dipoles are positioned very close to the wall, including when they are on bases.
Could I also put a dipole such as the M 500 D on a base?
In theory, dipoles can be placed on bases providing they are always near a wall, but we cannot supply any bases that are of the recommended height of 1.50 metres. Stability at this height can only be guaranteed if the base plate is very big.

A base of around 1 x 1 metre isn't going to look very attractive. Perhaps your joiner will be able to make you something that will match your room. Otherwise you should also use direct speakers for the surround channels, preferably of the same model as the front speakers.
Is it possible to set up dipoles behind the listening location on the rear wall?
Yes. Alternatively, you can also use wall brackets to position the dipoles behind your seating location at a height of 1.40 to 2.10 metres. Almost all Teufel dipoles have an integrated M6 tamping screw in the bottom to accept wall brackets.

We recommend mounting the dipoles using the suitable, optionally available swivelling L wall bracket and then aligning the dipoles at a 45 degree angle slant to the inner lying speaker-equipped side to the back wall and aligning the other speaker-equipped side to the side wall. This causes the dipoles at the back and side walls to reflect, thus generating the desired diffusivity.
The distance of the dipole-side equipped speaker to the room side wall should be at least 10 centimetres.
Is it possible to set up dipoles on bases to the sides of the listening location?
A set-up close to the wall is possible in principle, but we cannot offer bases with the recommended height of at least 1.40 metres. Stability at this height can only be guaranteed if the base plate is very large.

However, a base of roughly 1 x 1 metres is certainly not a pleasant sight. Perhaps your joiner will be able to make something that matches your room.

Otherwise, you should use direct emitters for the surround channels as well - the same models as for the front speakers is best.
Why does the automatic calibration of my AV Receiver report "incorrect" polarity for the rear speakers even though my dipoles are connected with correct polarity?
The reason for the error message is that the calibration functions were primarily designed for direct-emitting speakers.

However, as soon as dipole speakers are utilised, error messages can occur due to the spatial playback, because the dipole concurrently emits both phasings - the correct one and "the wrong one".

The reason why one speaker is displayed as "correct" and the other one as "incorrect" polarity is because sound is reflected variably due to the spatial conditions and consequently arrives variably at the measurement microphone. Depending which proportion of the sound is recognised by the microphone first, the receiver then decides whether there is (an assumed) false polarity or not.

Because polarity is visible based on the pole clamp markings on the speakers, you may ignore the measurement of the receiver.

What is the benefit of dipole speakers in the rear area (cinema version)?
Dipoles not only emit sound straight forward but also phase shift to the front and back.

This means that if you are sitting on an axis between the dipoles, the direct sound from the front and back sides of the dipole cancels itself out and you mainly hear room reflections. This simulates the sound field of a cinema where the surround channels of several speakers are reproduced.

The advantage of dipoles is that the surround field becomes wider and fills the entire rear area, whereas with direct speakers (normal speakers) you always hear the speaker directly. As a result, the sound experience with dipole speakers is always more intensive and emotionally stimulating.
How do dipole speakers work?
Dipoles do not simply emit sound directly forwards, but emit towards the front and back in shifted phases.

This means that if you were sitting on an axis between the dipoles, the direct sound of the front and rear side of the dipoles is cancelled and you primarily hear the room reflections. This simulates the sound field of a cinema where the surround channels are played back by several speakers in each case. That is why the dipoles are mandatory for THX Ultra2 systems.
How do I position the dipoles for slanted walls in an attic storey?
The dipoles should be hung on the slanted wall/ceiling to the side of your listening location.

All Teufel speakers have an M6 tamping screw at the bottom of the housing to fasten the dipoles to a sturdy L-Lock bracket, available in the Teufel accessories programme.
What are the advantages of dipoles as compared with normal, direct-emitting speakers?
Only dipoles can transfer the atmosphere of the cinema sound par for par to a living room. The surround field for dipoles is broader and thus fills the entire rear area, whereas for direct emitters (normal speakers) you always hear the speakers directly. As direct emitters sound similar to the front systems, the atmosphere that creates three-dimensionality is missing as compared with the dipoles.

The disadvantages of dipoles is the necessity of positioning them on the wall (upwards of 1.40 metres) and the more expensive price: They usually cost more than normal direct emitters, as you require the double number of chassis to be used. For limits in price, the following general rule applies: better have good sounding direct emitters than bad dipoles.
Where is the optimal place for the dipoles?
The dipoles should be best mounted to the side of the listening location at a height of 1.40 to 2.10 metres. Many Teufel dipoles already have an integrated wall bracket. We offer the corresponding brackets for the other models, e.g. the L-Lock bracket.

The dipoles then emit towards the front (direction of TV/screen) and the back (direction of back wall) so that direct sound is not heard at the listening location. The distance of a dipole-side equipped speaker to the back wall should be at least 10 centimetres. If your living room does not permit the assembly in the described form, we will be happy to advise you.
Are THX dipole surround speakers also suitable to play back 5.1 channel sound formats?
Of course.

The dipole surround speakers simulate exactly the sound fields of the speakers installed at the rear and side walls of cinema theatres, providing an especially impressive surround experience.

As it is impossible to mount a similarly large amount of surround speakers in your living room at home, the THX dipole surround boxes are the best space-saving way to transfer the surround effects to the home cinema.
They provide a precise positioning of certain sound effects, yet immerse the listener in a room-filling surround atmosphere.

One never has the impression that the sound is being directly emitted from a speaker.
How do I set the switch on the dipole?
Dipole setting: The speakers operate in phase opposition, i.e. if one side is transient, the other side dies out.

Bipole setting: The speakers operate in phase, i.e. both sides die out on the same side.

Monopole setting: Only the front side of the dipole is activated, i.e. the speaker works as a direct emitter.

On current dipole models (e.g. t 130 D) the two positions of the switch for the dipole and direct radiator mode are not specifically marked. If the switch is set towards the wall, the dipole mode is on. If the switch is set towards the speaker cabinet, the direct emitter mode is on.
Can I order the Teufel speakers in different colours than those offered?
To realise the very reasonable sales prices usual for Teufel, it is not possible to offer the speakers in a multitude of housing designs.

This circumstance would drive up the production and storage costs, which would result in a significantly more expensive sales price.

A paint shop in your vicinity will surely be able to repaint the speaker housing to your preferred colour without loss of warranty - after expiry of the eight-week right of return.
What is the advantage of bi-amping/bi-wiring?
Bi-amping means that the speaker can be operated by two amplifiers at the same time, or by a bi-amping-capable AV receiver. This enables the different chassis (for the treble mid-tone and bass range) to be individually supplied with one signal. Among other things, this could increase the sound performance of a speaker.

Bi-wiring states that the corresponding speaker can be controlled at the same time with two different speaker cables, meaning via separated input sockets for the treble and mid-tone range on one hand, and for the bass range of the frequency switch on the other. This could improve the sound even more. Bi-wiring is the prerequisite for bi-amping.
