Overview of our technologies

THX Certified
System 8 THX Ultra 2

In developing the System 8 THX Ultra 2, Teufel has attained two extremely ambitious aims, namely to outperform the legendary acoustics of the Theater 8 speaker set and to slash the enclosure dimensions.

Better, smaller & more stylish

After years of laboratory tests, countless prototyping cycles and extensive licensing procedures, it's finished: the System 8 THX Ultra 2: A worthy successor to the Theater 8 Ultra 2. Only better, smaller and more stylish!

Flat diaphragm

Optimised for wall mounting, the S 800 FCR front speakers boast contemporary flat diaphragm drivers in the bass and mid-range. The advantages of this include reduced distortion, minimised diffraction effects and ultra-low, mid-range and treble fade, all combined with the minimal interference of the virtually reflection-free grid. It may be 40% smaller than its predecessor but it boasts improved sound quality thanks to state-of-the-art driver technology, computer-aided Klippel optimisation techniques and intensive tuning work by our engineers.

THX Ultra 2 - no sacrifice on the home furnishing front

In unveiling its System 8 THX Ultra 2, Teufel reveals the first set of speakers with full high-end credentials which doesn’t dominate your living room but blends harmoniously into its surroundings. Top-spec home cinema can be elegant – with the System 8 THX Ultra 2.

THX Ultra 2 for your room

With the System 8 THXUltra 2 Teufel presents the absolute high end in THX Ultra 2 sound - a set that doesn't dominate but provides absolute dream sound. Elegant form with top home cinema atmosphere - the System 8 THX ULtra 2.

Expert Reviews 02/2011
“German speaker manufacturer Teufel is, in its own way, playing its part in making THX Ultra more affordable. By selling direct (and probably cutting out around a 30 per cent retail margin) it sells sets of THX speakers at prices that until recently you would only find on avforums or ebay. We may be committing home cinema heresy here but we think this direct approach is way overdue… We would far prefer to pocket the saving and have a better set of speakers in a cinema room. On top of this, Teufel offers a full returns service within 8 weeks of invoicing (note, not delivery)… the System 8s are neither small nor cheap but they put THX Ultra 2 within touching distance of the well-heeled enthusiast with a 50m³ or larger listening space.”

"Licence to Thrill"
Heimkino 03/2010
"Teufel delivered a true masterpiece with the Theater 8, which now enjoys a cult status. It's hard to imagine this performance could be topped, but Teufel's engineers have done just that with System 8. This THX-certified home cinema system outdoes its legendary predecessor in a number of ways. Not only is it more fascinating, harmonious and agile, but it can also be incredibly fun through either its corporeal or more subtle qualities. At the same time its new compactness makes it suitable for integration in a range of living spaces. Anyone seriously thinking about setting up a home cinema or even building a larger installation in a basement or attic shouldn't miss out on a chance to listen to this system."

"An acoustic top performance like this in combination with living room compatibility and an attractive price is worthy of our most coveted rating.”
Area DVD 01/2011
"With comparatively compact living room friendly components, the System 8 creates a surround sound environment without equal. A multi-faceted wealth of detail in all frequency ranges and a clear transparency in the sound image with a well-defined, dense atmosphere and finely delineated structure in the deeper frequencies produce a home cinema experience without compromise. The subwoofer warrants special notice as the relatively compact 80 liter enclosure bombards the room with a monstrous bass deluge, extremely good depth, and astonishing fine dynamics that only larger devices are usually able to achieve. The higher frequencies seamlessly contribute to the overall effect, characterized by dynamism in the vocals with a broadly differentiated gradation and a clearly differentiated high end that remains very pleasant even at high levels. An acoustic top performance like this in combination with living room compatibility and an attractive price is worthy of our most coveted rating.”

Help regarding this product
Do I also have a 6.1/7.1 playback for a 5.1 recording?
Usually, all 6.1/7.1 AV Receivers can generate a 6.1/7.1 playback from a 5.1 recording. The procedure is comparable with the Dolby Pro Logic Decoder, which generates a matrix circuit from the stereo signal of a centre channel.

The AV Receivers thus generate a rear centre channel from the rear R/L channels of a 5.1 recording through the matrix circuit. The stronger the rear R/L effects on the DVD, the stronger the signal from the rear centre.
Can I connect the LT 4 directly to a DVD player or PC?

The LT 4 is a partially active system that requires AV receiver operation. It has a built-in amplifier that only supplies bass tones in the subwoofer housing That is why an "AV Receiver", i.e. a combination of radio receiver and multichannel amplifier, is essential for using the LT 4.

The subwoofer is connected from the Line In R input to the AV receiver's sub out jack using a mono RCA cable, while the three front satellites are connected to the three speaker outputs of the AV Receiver using the speaker cable and are supplied with power from there.

Connect signal-emitting source appliances such as DVD player or PC etc. directly to the corresponding input jacks on the AV Receiver.
When would it be worth upgrading my 5.1 system to 6.1/7.1 sound?
Naturally 5.1 channel systems that play back all of the sound tracks contained on the DVDs already offer an excellent home cinema experience.

For the new 6.1 or 7.1 sound formats, a rear centre channel is controlled in addition to these channels. This channel, coded in the stereo effect channels, enables the better positioning of effects and music signals directly behind where you are sitting.

If using two speakers for the rear centre channel, the optimal seating position is not tailored to an individually specified position, i.e. you don't have to be seated in the exact centre.

In the following cases we would recommend upgrading to a 6.1 or 7.1 system:

• Your sitting position is not always dead centre, or you often have several viewers

• You have had a 5.1 system for a very long time and would like an improvement

• Your AV amplifier/receiver is designed as a 6.1 or 7.1 receiver and offers the corresponding connection possibilities

• You can also set up one and/or two rear centres. If you are currently building/renovating your house or flat, we would recommend you lay the cables for the additional rear centre channels in any case.

• Modern BluRay players usually issue a true 7.1 surround sound signal at all digital outputs and are thus optimally suitable - presuming the relevant AV Receiver - as a signal transmitter for a 7.1 channel home cinema system.
How do I upgrade my system to a 6.1 or 7.1 sound format?
The choice of speaker(s) depends on the AV Receiver/amplifier. This has an additional power amplifier for one rear centre (6.1) or its two (7.1). You can easily see this by the wattage (e.g. 6 x 100 watt or 7 x 100 watt). To the existing (side) rear speakers for right/left (5.1 technology), one or two additional rear centres are utilised in addition (6.1 or 7.1 technology).

• My AV amplifier/receiver has six connections/power amplifiers (6.1):

In this case we recommend connecting the same centre at the rear that you also used in the front area.

• My AV amplifier/receiver has 7 connections/power amplifiers (7.1):

If you already use dipoles or direct emitters for your 5.1 system, then you have a choice of either supplementing two more dipoles or two direct emitters. For wall assembly and a short distance from the seating location to the rear wall (less than 1.00 metres), we would recommend dipoles. As soon as you want to set up the speakers on bases or on a shelf, then direct emitters would be the better choice.

Even if the AV Receiver/amplifier only has the connection and power amplifier performance for one rear centre, it is still possible to connect two instead of just one speaker through series connection.

• The AV amplifier/receiver has seven connections/power amplifiers, but I can only set up one rear centre. As the 7.1 AV amplifiers/receiver also offer the option of operating just one of the two outputs (usually can be set in the speaker set-up!), you can also only connect just one rear centre.

Here we recommend connecting the same centre to the rear that you also used in the front area. For short distances to the listening location (less than 1.00 metres), a dipole would be the better choice - especially if you are also using dipoles at the sides.
Is it a problem if the speakers are at different distances to where you are sitting?
Since the distance and volume of every individual speaker can be adjusted for the digital home cinema receivers, asymmetrical set-ups can be easily compensated. 
How do I equalise my home cinema system with the help of a sound level meter?
Take the level meter with you to the listening position and point the measuring device directly towards the front centre speaker. Now start the sound generator of the receiver (or of the sound card or DVD player) and equalise all speakers in succession to the same level.

The position and alignment of the measuring device should not be changed during this procedure. For a Teufel sound level meter, proceed as detailed in the following:

1. Remove the protective tab from the battery.

2. Set the weighting to "A" - only the "A" position considers the full frequency range during measuring!

3. Set the response to Slow.

4. Set the Range to 70.

5. Start the test noise from your AV device.

6. Change the volume for every individual channel at the AV device so that the level meter shows 75 dB (meaning between +4 and +6).

7. Done!
What is the difference between the 5.1 and 7.1 configuration?
Compared with the 5.1 set, the 7.1 set has two extra speakers for the back rear centre channel.

The 5.1 channel set plays back all sound tracks on DVDs/Blu-rays and creates an excellent home cinema experience.

With the 7.1 sound format, a rear centre channel is also generated in addition to these channels and distributed to two further speakers (the "rear centre"). This channel, which is encoded in the stereo effects channels, allows better location of effects and music signals directly behind the sitting position.

If you use two speakers for the rear centre channel (i.e. installed 7.1 set), the optimum sitting position is not restricted to one specific place, so you don't have to be sitting exactly in the middle and several listeners can enjoy the best sound.
Where is the optimal place for the centre of my Lautsprecher Teufel Surround System in a 5.1/6.1/7.1 configuration?
Because the centre plays back spoken dialogue, this speaker must be positioned as centrally as possible under or over the TV/monitor or the screen.

If the centre is placed outside the area of 40 centimetres to 1.20 meter height, it should be slightly inclined or angled towards the listener.

Why don't the THX Select and THX Ultra 2 have five identical speakers?
A cinema uses completely different surround and front speakers, as they must fulfill completely different tasks.

The front speakers guarantee clear voice reproduction and very good positioning that harmonises with the picture.

The surround speakers, on the other hand, generate a diffuse and non-traceable sound field that literally surrounds the viewers and enables the illusion of a helicopter flying over the audience, for example. If you want to set up a 5.1 home cinema system with conventional speakers, then five identical speakers plus a subwoofer are the minimum equipment.

THX speaker systems, however, are specifically designed for multi-channel playback. That is why THX front speakers and THX dipole surround speakers offer the best requirements for perfect sound playback from a psychoacoustic view.

Despite the very compact dimensions of all utilised speakers, the THX subwoofer provides a very dynamic and powerful bass playback.
Does it make sense to connect THX Ultra 2 speakers to a THX Select amplifier?
Since the requirements for THX Select devices regarding cut-off frequency, THX switches and speaker control are comparable, a THX Ultra 2 speaker system can indeed be combined with a THX select receiver.

The main difference to the THX Ultra 2 devices is their higher performance which is only necessary for an approximate room size upwards of 50 m².
How is THX Ultra 2 specified?
THX Ultra 2 is the first THX standard that was completely developed for digital home cinema sound standards.

THX Ultra (1) was still based on the "original" Home THX, which was already used in high-quality AV amplifiers/receivers during ProLogic times.
Do I need a THX amplifier for the THX speakers?
Not necessarily!

The receiver/amplifier must have bass management where the frequencies are distributed for the THX front/centre speakers and the THX subwoofer (cut-off frequency 80 Hz).

Also, the amplifier should exhibit a minimum rating of 100 watt per channel and match the speakers for performance (amplifier sine wave output = approx. long-term load of speaker).
Are THX speakers suitable for listening to music?
Of course.

Since THX speakers are optimised to play back multi-channel signals (4 or 5.1 channels), the front speakers permit the precisely staggered and very true to detail spatial playback, while the surround speakers ensure realistic room characteristics.

Both are also ideal requirements for playing back music.
Is THX compatible with Dolby Digital and DTS?

The objective of THX home cinema systems is to play back film soundtracks with as much authenticity and quality as the original mix from the sound studio.

In all studios used for film dubbing, the soundtracks are mixed in a 4-channel version (Dolby Surround) and in a 5.1 channel version. The acoustics, equalizer settings and speaker configurations are absolutely identical.

THX systems are thus always able to play back soundtracks produced in this way absolutely true to the original. Because of the high technical and tonal requirements, the THX standard can be compared with the TÜV (German Technical Control Board) for cinema sound.

As opposed to the THX quality standard, DTS and Dolby Digital are procedures for compressing sound data.
What is so special about a THX System?
THX systems are the ultimate home cinema components.

All THX-licensed devices and speakers must demonstrate certain technical properties so that they can play back movie soundtracks produced for cinemas and correspondingly powerful cinema sound systems absolutely true to the original for home cinemas as well. This is only possible up to a certain point with conventional hi-fi systems.

The most important requirements for excellent home cinema sound are:

• That despite the considerable size difference between cinemas and home cinemas, the movie soundtrack can be played back in comparably smaller rooms with the correct tonal balance and three-dimensionality.

• That all sound channels are played back very precisely despite the complexity of a multi-channel soundtrack to be able to precisely locate and allocate all noises and voices.

• That the subwoofer is perfectly coupled to the main speakers.

• That the front speakers are (by sound) identical - indispensable for harmonious sound playback.

THX systems satisfy these requirements perfectly, as they consider all running processes concerning playback while the movie soundtrack is being mixed.
What are the differences between THX Ultra 2, THX Select and THX Multimedia?
THX is a quality standard that guarantees the best possible playback for a specific room size. Since THX was originally developed for cinema theatres, the specifications apply to room sizes that far exceed the average living room size.

THX currently differentiates three standards for speakers: THX Ultra 2, THX Select and THX Multimedia.

THX Select 2 only applies to AV Receivers/amplifiers.
THX Ultra 2 corresponds to the earlier THX with the uncompromising design of the components.

Comparison of the three THX standards:

Front speaker
• THX Ultra 2: Angle of radiation and frequency response strictly limited requirement, D'Appolito arrangement of speaker systems prescribed.
• THX Select: More generous specifications for angle of radiation and frequency response.
• THX Multimedia: Radiation behaviour corresponds to THX Select.

Surround speaker
• THX Ultra 2: Dipoles are compulsory.
• THX Select: Dipoles recommended, but not compulsory.
• THX Multimedia: Direct emitters in every respect.

Subwoofer - transfer frequency

• THX Ultra 2: 80 Hz
• THX Select: 100 Hz
• THX Multimedia: 130 Hz

Volume level

• THX Ultra: Continuous load 105 dB (front) / 102 dB (surround).
• THX Select: Short term load 105 dB (front) / 102 dB (surround).
• THX Multimedia: 103 dB at the listening location/desk at approx. 50 cm distance.

Performance profile

• THX Ultra 2:
More output performance than normal AV Receivers. Complies with the strictest requirements for minor background noise and minor distortion. Is designed for performance needs of large listening rooms up to 150 m².
• THX Select:
Structure of AV Receiver is simpler and thus more reasonably priced. Less performance required, therefore suitable for smaller and medium-sized listening rooms up to approx. 50 m².
• THX Multimedia:
Pure PC and/or multimedia speakers for use at the computer.

Speaker set-up

• THX Ultra 2: Arrangement and set-up strictly regulated.
• THX Select: Set-up and arrangement simpler and more flexible.
• THX Multimedia: Set-up of front speakers on the desk, rear speakers to the side and behind where you are sitting.
How can I upgrade my THX system to a 7.1 sound format?
With the THX 7.1 amplifiers/receivers, there is always the option of connecting two rear centre speakers. We would also recommend using four rear speakers. Due to the elaborate development of our rear speakers, our models can be used very flexibly for any application. Here we have to differentiate as follows: - You have a THX Select/Ultra 2 device and want to connect two rear centre speakers: if you already use dipoles or direct radiators in your 5.1 system, you have the choice of adding either two more dipoles or two direct radiators as rear centres. For wall mounting and/or at a short distance from seat to rear wall (less than 1.00 m), we would recommend dipoles that are also operated in dipole mode (for System 4 THX, for example, order 2 x additional S 400 D). As soon as you want to place the speaker on stands or on a shelf, we would recommend direct radiators (for System 4 THX, e.g. order 2 x additional S 400 FCR). As soon as you already use direct radiators with your 5.1 system, we would recommend the same type of direct radiators for the upgrade. You have a THX Ultra 2 unit and want to connect two rear centres: a circuit especially developed for THX Ultra 2 devices allows you to use two more direct radiators or two more dipoles in addition to the dipoles used as rear effect loudspeakers.
What's behind THX Optimode?
THX Optimode is the latest development of the THX Digital Mastering Program consisting of a series of tests that enable every home cinema user to adjust his system exactly in picture and sound to the Optimode DVD currently in the DVD player.

The first DVD that supported the new feature was "Fight Club" in the Special Edition by 20th Century Fox (NTSC version). The offer has been continually expanded in the meantime.

The tests, which can be played on NTSC as well as PAL DVDs, consist of video tests that are helpful in optimally setting and configuring the TV or video projector, as well as audio tests that guarantee that the sound system is configured perfectly.

The special thing about these tests is the fact that the measuring signals are identical to the reference signals that were used during the final mixing of the relevant DVD. The home cinema system can therefore be co-ordinated accurately and individually to every single DVD with THX Optimode.

The goal of the entire procedure is that the sound and particularly the picture should appear in the home cinema exactly as the producer imagined. Let's assume the film producer wanted to create a certain mood in the film using specific colouring; this only works in the home cinema if the screen at home is just as co-ordinated as in the studio. Thanks to THX Optimode, that is guaranteed as far as possible.

Operating THX Optimode is just as easy: The software on the DVD includes all of the tests. Individually, these are video tests to set the contrast, brightness, colour, colouring, control of the correct ratio of picture length to picture width and the possibility to test the general qualities of the monitor.

In addition, there are audio tests for the phases of the speakers, connection of the speakers and the cut-off frequency of the LFE (subwoofer channel). Some tests will clearly show when it is necessary to consult a specialist for the settings.
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.
