Overview of our technologies
The CoreStation uses a premium amplifier from Texas Instruments for the highest level of performance along with the least amount of noise. Thrilling dynamics and the finest details are played back along a with a linear frequency response ranging from 20 to 40,000 Hz. So equipped, the CoreStation has no problem playing comparable AV receivers in the 700 Euro range against the wall.
In addition to its incredble performance values, the CoreStation boasts an innovative fanless construction. Our engineers in Berlin designed the system wth heat sinks instead of fans. This makes the CoreStation not only nearly noiseless when in operation, the absence of a mechanical cooling system is what allows for the CoreStation's compact dimensions.
FM radio and Bluetooth are also including making it easy to tune in to all your favorite podcasts as well as connect to the best music streaming services. Stream music from Spotify or YouTube from your smartphone or tablet to the CoreStation for clear and powerful playback.
The optional Wireless Audio Set, available separately, allows you to control the rear speakers wirelessly.
The RearStation and SubConnect connect to the rear speaker and subwoofer wirelessly
The RearStation transmits the signal to the rear speaker
Thanks to HDMI CEC, it's possible to control volume levels with your standard TV remote. A simple initial pairing procedure is all that's required.
An optional high-end TV and loudspeaker bracket (VESA compatible) makes it possible to wall mount the satellites along with your TV as a single unit. Integrated keyhole brackets allow the satellite speakers to be directly wall mounted as well. In addition, the speakers can be placed on stands or on a lowboard, making the Varion Complete "2.1 Set" one of the most flexible home cinema systems on the market today.
In spite of slender dimensions measuring just 7 cm across, the Varion offers everything you would expect of a full-fledged surround sound system.
- - A 2-way system: The incoming audio signal is divided and sent to the drivers best designed to play it back.
- - Seven drivers per speaker: Each speakers produces a full, rich and power-packed sound with excellent speech intelligibility, even at low volumes.
- - High excursion drivers: Powerful and agile driver units produce high distortion-free levels.
- - 19 mm tweeter. A large, centrally positioned tweeter reproduces voices and effects with a silk, soft sound that is never aggressive or shrill.
- - D’Appolito Array: Centering the tweeter between three midrange drivers on each side results in a better, more even dispersion of the treble range.
- - Broad sound dispersion: The wide angle of sound dispersion makes it possible for everyone in the room to enjoy thrilling sound.
All of the Varion speakers are identically constructed, an essential requirement for a truly harmonious and realistic surround sound. Experience helicopters or thunder pass overhead without any gaps in the well structured soundstage.
Neutral tuning accompanied by deep but realistic and well-integrated bass is perfectly suited for movie sound tracks but also makes the most out of gaming sound and music.
The subwoofer is controlled wirelessly. Audio transmission is lossless and without delays. You only need one cable connection.
There is a tuner and bass reflex tube on the underside of the device. The bass reflex system allows for deep, strong bass even from such compact dimensions.

"The surround components really run with the ball and the spatial impression is well developed. The engineers did a very good job managing the calibration between the individual frequency ranges. The mids are reproduced from the centre in an easily understandable form and the treble is always clear.”

"From zero to 60: With the Varion range, Teufel once again pulled a series from up its sleeve capable of transforming the occasional movie watcher to a home cinema enthusiast within a short period of time. With the Blu-ray complete system, the Varion Impaq Streaming, as the flagship combination, there’s a bundle that not only offers fun with movies, but also an easy introduction to the exciting world of multi-room streaming. Sound good? It is! But that’s not all…”
“Since we already tested the Impaq 8000 Blu-ray receiver with the Cubycon ensemble, we got our hands on the same Blu-ray action film we used then, “John Wick” [...].”
"… when it comes to movie sound, it’s not just about making a lot of noise, but rather the creation of a realistic soundstage.”
"This is unquestionably what we experience with the Varion ensemble [...] The short bits of dialogue are crystal clear and the individual sonic details are even more precisely placed. For example, a gun hit out of a hand in a somewhat quiet setting can be acoustically localized exactly there where one would expect it based on the path of flight. Very precise work from both the contract killer on the screen as from the Teufel development team.”
"The oft-employed concept of listening pleasure is not adequate to the agile and passionate way with which the Varion speakers go about their business. All about us, the wheels seem to screech, paint is being scratched and shots fired. Muffled crashes are intermixed with grating collisions that are always precisely embedded in the voluminous soundstage. At the very latest, it becomes clear with the onset of rain at the showdown that the slender Varion speakers have no problem simulating a storm and that only a sprinkler system is missing in order to complete the illusion.”
“When it comes to music, the Varion naturally also shows what it’s made of […].”
"Above all, the 3-dimensional presentation is immediately apparent. In spite of the fact that the speakers are placed relatively close together, the front speakers open up a broad stage right away and supply [...] a great deal of space for the sound to develop.”
"Versatile, attractive and talented [...]. Teufel sets a high standard with these diverse Varion combinations and succeeds in applying merciless pressure on the competition.”
Note: This test report refers to the Varion Impaq.

"The voices separated themselves well from the centre speaker and had clear contours. Once the song really got going, the clear, well-defined sound was impressive. The Varion set doesn’t produce a cheap “fun sound,” but rather plays in a manner that is serious and complete. The treble range has an impressive 3-dimensionality, comes across as truly free and transparent and is well-integrated with the midrange. The separation of voices and instruments also hardly offer any points for criticism. The synthesizer, the drums as well as the electric guitars are charismatically presented. Morten’s voice is successfully emphasized without pushing the instruments into the background. The US 2106/ delivers a precise and credible bass that isn’t artificially "pumped up.“
"The focus on the vocal elements is successfully achieved in a masterful manner and yet the instrumental sections are not subordinated. The spatial depth is convincing, the processing of details as well as the definition is excellent for such a set.”
Film: "Batman, The Dark Knight“ in Dolby TrueHD
"The shots in the bank’s spacious service area are very forceful, the echoes, conditioned by their environment, are convincingly produced. The opening of the door to the vault and the use of the special drill on the massive vault door are wonderfully accentuated.”
"The front-surround transitions are cleanly balanced, a very good 3-dimensional expansiveness and a precise localization of small as well as larger effects and effect combinations confirmed the following for us: The Varion 5.1 set can be recommended for challenging tasks like the highly differentiated playback of movie sound at high volumes.”
“Even in movie sequences in which suspense is built up but in which larger effects are missing, the test ensemble maintained a sensitive, atmospheric and well executed soundstage.”
2.1 Mode: "California Dreamin‘“ by Diana Krall:
"And we’ve concluded that the collaboration with the US 2016/1 works very well, even in 2.1 mode. We liked the well-rounded and at the same time clear and direct soundstage. The resolution is immaculate for such a set […].“
"It’s surprising how good the voices separated from the speakers and distributed themselves in the listening room. We really liked the Varion speakers’ and the active subwoofer’s free, unforced playback.”
"Chic and powerful loudspeakers with flexible placement options, perfect for the present day. It’s barely possible to fault the sound produced by the slender speakers. With very good definition, excellent speech intelligibility and flawless power handling, it’s possible to enjoy music and movies even at high volumes at an astonishingly dynamic and cultivated level. The exceptionally good quality is not only evident in multi-channel playback, used as a 2.1 system, the presentation of stereo material is always comprehensive. That the Varion is offered in many sets, including complete, plug-&-play bundles, is to be praised as this makes it possible for everyone to find the perfect system. From a 2.1 set to 5.1 streaming ensembles with the Raumfeld Connector and Impaq Blu-ray receiver, everything is on offer. The prices are completely reasonable […].“

"The TV presenter Jens Riwa was perfectly understandable, and even documentaries with only limited Hi-Fi sound sounded extremely lively and complex."
"It revealed fine details in recordings and reproduced the voice of Metallica frontman James Hetfield with just the right amount of grain. The Teufel set also had another positive feature when playing the Metallica tracks: the levels are really well balanced."
"We didn't find any real flaws in the Teufel Varion."
"They were created to improve the quality of television sound for a good price. This is really impressive. The bright sound of the set is not ideal for classical music, but is absolutely ideal for the probable range of use. Thanks to its design, the system is also good for use not only in living rooms and bedrooms, but also in shops. The variability (2.1 or 5.1) is just as great as the practical and robust design. A range of matching accessories makes the Varion package even more flexible and attractive."

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.
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.
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.
• 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.
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).
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.
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.
Actually, it should be quite simple: Connect the speaker cable to the amplifier and speakers with the correct polarity and you're done. Unfortunately, many manufacturers of home cinema receivers put stumbling blocks out for the users in the form of specifications on the rear of the device and/or in the operating instructions. These usually look like the following (translations): Minimum connection impedance six ohm! Or, speaker impedance six to eight ohm. And what is the problem? There are hardly any six ohm and only a few eight ohm speakers available in Germany. Most of the speakers sold in Germany have a nominal impedance of four ohm. So theoretically, you shouldn't connect them to most of the receivers and amplifiers.
To explain why it is possible after all, we would like to briefly explain the electrical engineering principles: The impedance of a speaker is nothing other than its electrical resistance which it puts up against the flow of current.
• Low resistance = high current
• High resistance = low current
Important to know for operation with an amplifier is that the impedance is not the same for all frequencies but can, for example, change between 50 and 200 hertz by 50 percent. So it isn't entirely correct to speak of impedance for a speaker per se, rather one must always consider the behaviour across the entire range between 20 and 20,000 hertz. To still achieve a reasonable connection value for amplifiers (which, by the way, says nothing about the output impedance of the amplifier itself but rather only which impedances may be connected to it), the creators of the DIN Standard have applied the following stratagem: Only the minimum value of the impedance in the audible range is decisive for the nominal impedance value. This is where the most current flows and the amplifier is subjected to the highest load. Speakers with eight ohm nominal impedance may only exhibit a minimum of 6.4 ohm, and those with four ohm nominal impedance 3.2 ohm. Six ohm are not defined in the DIN (which is applied internationally), but one could use the above values to interpolate that they may exhibit a minimum of 4.8 ohm.
From the definition it is apparent that the nominal impedance is only a rough benchmark, because it says nothing about how the entire course of the impedance looks. No matter whether it only reaches less than 6.4 ohm at one point and is otherwise beyond that, or if the impedance moves close to 3.2 ohm across the entire range, but does not drop below that. The last speaker is surely much more stressful for the amplifier, but has just a nominal impedance of four ohm as the other higher ohm one.
Conventional speakers usually exhibit one to two minima in the bass range, and there is one frequently in the treble range. These minimum values are usually not especially broadband. Aside from the minima, the impedance is usually far higher than the nominal impedance. The amplifiers are really stressed in the bass range because firstly, this is where the most energy is for music and especially the home cinema sound, and secondly, they have to let the most current flow through the impedance minima here.
And lastly, the main reason why many manufacturers don't want four ohm speakers to be connected: In extreme cases - for deep frequencies of consistently 3.2 ohm - the amplifiers in multichannel operation become very hot. A lot of current also means a lot of power loss and thus at lot of waste heat. However, much has to come together before that happens - namely high performance for a longer period of time and setting up the device without sufficient ventilation.
But this extreme case is seldom met in practice. As mentioned above, most of the speakers are not as critical by far, and it is extremely rare to listen to an exorbitant volume for a longer period of time. That is why it is not a problem from a technical point of view to connect speakers with four ohm nominal impedance to all modern home cinema amplifiers and receivers.
However, there is one small catch: The question of warranty. Should a defect occur to the device - which doesn't even have to do anything with the speakers - and the manufacturer notices that four ohm speakers were connected despite the specifications to the contrary, he could refuse repairs due to improper use. As discussions with manufacturers and distributors have shown, this is highly unlikely because they are also aware of the problems.
And for purely legal reasons, Lautsprecher Teufel may not give you a warranty either that your amplifier or receiver will tolerate four ohm speakers. We can only pass along one experience: For several years, the listening tests of the trade magazines are done exclusively with four ohm speakers, and not a single defect has occurred as yet even though the devices are driven to their limits. Also, the performance of each device is usually measured at four and eight ohm irrespective of the specifications of the manufacturers, and the load here is also considerable. It has been a long time since measurement laboratories have seen failures due to to low load impedance.
There are still some special cases, which should be briefly mentioned: Amplifiers/receivers with impedance switches give cautious natures the possibility to stay on the safe side under all possible conditions, even with the warranty. The four ohm setting of the corresponding switch reduces the supply voltage of the power amplifiers so much that excessive heat cannot occur even under unfavourable circumstances. However, the maximum power is then reduced somewhat.
During the listening tests of the trade magazine, these devices are always switched to the "eight ohm" setting to tease out the maximum performance reserves. A defect here has yet to occur. When choosing devices, take a close look because there are devices that only permit speakers with a minimum of six ohm despite the impedance selector switch, like the Pioneer VSX-D2011, for example. This is remarkable in another respect: It possesses a THXSelect license. This license is only issued if certain measured values are complied with that are determined at four ohm for at least the front and centre speakers.
If the THX laboratory had proceeded according to manufacturer's specifications, the VSX-D2011 would never have received a licence, as it would not have been permitted to perform the necessary measurements. By the way: this is also the case for other THX Select devices. But you needn't worry here: The THX logo not only offers additional security, but also a good lever should a manufacturer once refuse a warranty.
The AUDIOVISION TIP
Overheating is the main problem that can occur through the combination of four ohm speakers with power amplifiers that are not released for this.
Therefore, in case of doubt:
• Always set up the AV Receiver or amplifier in well ventilated places and never in a closed housing or close to the heater.
• Occasionally check the temperature of the device.
• Reroute the bass elements via set-up at the subwoofer, if possible.
However, for a record player an additional phono preamplifier is required - these are available from specialist retailers for around €50.
1. Remove the RCA cable from the input on the subwoofer. If the hum is no longer heard, go to point B. Otherwise, follow point A.
A. Attach the net cable of the subwoofer to another electricity outlet (i.e. Kitchen/Bathroom/Bedroom). If the subwoofer still hums, get in contact with our Support team.
Should the hum no longer be there, the disruption was a problem in your power supply, which can, for instance, be caused by dimmers or chargers. To find out where the disruption is, unplug all your devices and work back from there. As soon as the hum is heard, you now know your source of the disruption.
B. In your case, the "ground hum" is responsible for the disruption. Please proceed as follows to discover your source.
- Disconnect the cable or satellite port from the TV Receiver and check if the hum disappears or not. If it does, you can use a sheath current filter for the cable outlet to prevent this. For example, the sheath current filter AC 9022 ED. If you have a satellite connection, connect the Satellite Receiver to the optical cable playback source - Teufel Optical Digital Cable
- If this reason can be excluded, separate all devices from the AV Receiver one at a time until the hum stops. The last connected device is then your hum source and should be separated from the others using a galvanic separation filter (found in a retail shop)
- If this doesn't work, get in contact with us once again so that we can give an individual, helpful response.
The corresponding setting in the speaker set-up must be adjusted individually for each source for many receivers, however, e.g. for CD playback only front without woofer, and front speakers plus woofer for Dolby Surround video playback.
To make sure the subwoofer switches on and off correctly in automatic mode, (to be selected on the corresponding switch of the subwoofer, such as "Auto / On / Off"), we recommend turning the level control on the subwoofer to 1/3 or perhaps to 1/2 and increasing the output level for the sub in the receiver's speaker set-up – sometimes up to the maximum (+10 dB or +12 dB). The subwoofer should then work perfectly.
The maximum position of the output level in the speaker set-up of the AV Receiver is obligatory for some of our models (e.g. the Concept S subwoofer).
You can connect it like a standard speaker system: the five satellites via speaker cable to the corresponding speaker outputs front R/L, rear R/L and centre of the AV Receiver/amplifier and the subwoofer from the front R input via a mono-RCA cable to the Sub Out output on the A/V Receiver/amplifier.
The auto on/standby switch only responds when the front R input is being used! The subwoofer also receives the full subwoofer signal via this channel.
If the AV Receiver/amplifier has preamplifier outputs for all channels (front R/L, rear R/L, centre and subwoofer), the Teufel set can also be connected via three RCA cable pairs to the subwoofer and the satellites via speaker cables to the subwoofer. However, we recommend using the first version.
Separate the direct connection by a grounding filter for the antennae cable that is created for it - for instance, the Teufel modell sheath current filter AC 9022 ED. Alternatively, you can use a galvanic separation filter that is looped into the connection between the subwoofer and AV Receiver.
The hum disappears if the antennae cable is separated from the Receiver/Tuner/TV. First try the grounding filter, otherwise the galvanic separation filter.
Placement within the straight line between both front satellites is ideal - but not precisely in the corner of the room because certain frequency components could be unpleasantly excessive when played back.
The membranes of the satellites should move to the front at the same time as the membrane of the subwoofer bass speaker, because all speakers of the system must vibrate in phase for optimal playback. This means that (provided the connection has the correct polarity) all drivers must move in one direction when the three front speakers receive a pulse (towards the outside or towards the inside).
If the subwoofer is in line with the front speakers, its bass speaker should have the same direction of movement (phase) - the controller on the woofer is set to "0". If the subwoofer is not between the front speakers, but is to the side of or even behind the listening location, its phase length will not match that of the front speakers. That is why the phase of the subwoofer must be changed in such cases.
So much for the theory. In practice, this means: Listen to a loud piece of music with heavy basses and ask a second person to change the phase during playback. The correct setting of the phase switch depends on where the subwoofer is positioned in the room. The position where the bass playback (above all the upper bass range) sounds the fullest is the correct position. Have fun trying it out!
Even though the LED is still illuminated, the subwoofer is in standby mode. This function can be easily checked by slowly increasing the volume at the receiver/amplifier. You will hear a quiet popping noise when the subwoofer activates itself as of a certain level.
If the satellites are not connected directly to the subwoofer but to the AV Receiver/amplifier via speaker cable instead, the subwoofer performance will increase somewhat; the power amplifiers for the satellites have no function. This enables the subwoofer and satellites to play even more dynamically than if the subwoofer still had to provide the satellites with performance.
The technical background: The subwoofer has a large transformer with a specific wattage. This performance is either distributed to the five satellites and the subwoofer, or you receive a higher performance only for the subwoofer.
If the cabling method is easier for you, then you can alternatively connect one subwoofer to the other. You will need two mono cinch cables - one to connect the subwoofer "Pre Out" on the AV receiver/amplifier to the left line-in input of the first subwoofer, and the other to connect the left line-out output of the first subwoofer to the left line-in input of the second subwoofer.
The wattage (e.g. "360 W") printed on the rear of the subwoofer near the mains plug designates the ability of the power amplifier "to pull" a maximum power rating in the specified range at the moment of switching on (those 360 watt stated as an example).
Consequently, the wattage must correspond to at least the sine wave output of the amplifier, as this sine wave output must be permanently available which the power pack must provide as well.
The pulse/music performance of the amplifier, on the other hand, can exceed the wattage, because the short pulses are buffered additionally by the capacitors in the power pack and are not achieved solely through the performance of the power pack.
The wattage for a multi-channel subwoofer can also be below the sine wave output, as the specified sine wave output is not requested from every channel at the same time.
For a 5 x 100 watt sinus power amplifier, for example, each of the five channels is able to implement 100 watt sine. However, not all five channels at the same time! This is also unnecessary, as the same signal is never transmitted across all five channels at the same time, thus requesting the same high sine wave output per channel.
That is why the wattage may be, e.g. 300 watt, even if the sine wave output exhibits 5 x 100 watt (= 500 watt).
The volume of the active subwoofer can be controlled so that you can adapt the relationship between the active bass and treble / mid tones to suit the room.
Use your own senses to judge which settings sound best in your room. This switch is especially useful in stereo mode. On the other hand, multichannel amplifiers often have technologies that adjust the subwoofer volume - so when using a multichannel amplifier the controller should first be set at 0dB.
It is calculated of the sound velocity divided by 2 and divided by the room length [ 340 m/s: 2 : 6 m = 28.3 Hz (=1/s) ] or, more simply: 170 divided by the room dimension (length, width or height). The greatest distance between two parallel walls is taken as first standard value. For a room of 4 x 6 metres, this would be 6 metres. Strictly speaking, you would have to calculate the room resonance frequency for further parallel walls (for the 4 metres and for the ceiling height).
Overlaying resonances are also possible if the room dimensions are very close to each other. (2.8 metres high, 3 metres wide and 5.6 metres long). The resonance at 2.8 metres is repeated as multiple (times 2) at 5.6 metres length, the resonance of the 3 metres width is close to the resonance of 2.8 metres. It would resonate strongly here at 30 Hz, 56 Hz, 60 Hz and 120/112 Hz.

• For example, a man with a deep voice speaks in a very small room (2 by 2 metres, 85 Hz). The voice appears to have more emphasis than in another room or out of doors. As soon as a woman speaks, the voice will sound just the same as in another room.
• The voice of a woman or that of a small child will cause glass to shatter. The voice strikes exactly the tone that corresponds to the resonant frequency of the glass. The glass resonates so strongly that it shatters (refer to the movie "The Tin Drum").
• A group of soldiers march across a bridge in cadence. The equal movement causes the bridge to vibrate so much that it collapses. That is why no one marches across bridges in cadence.
