Overview of our technologies

Downfire
Sound with perfect power and grace

The LT 4 takes movie soundtracks, music, and games and transforms them into sonic events you can feel. The following acoustic features make this experience possible:

  • A 3-way system distributes the incoming audio signal from the A/V receiver to five different drivers that are optimized to play back their dedicated frequency ranges. This results in a better sound than that produced by a 2-way or broadband system.
  • A total of four larger 75 mm midrange drivers ensure full, deep playback. The only thing thin about this system is its columns. .
  • Long-throw drivers produce high, precise and distortion-free levels
  • A large 20 mm tweeter endows voices and effects with a silky, highly detailed tone without sounding shrill or aggressive
  • In spite of the slender columns, the crossover frequency to the subwoofer was set at 120 Hz. This makes it difficult to localize the bass which means more flexibility when positioning this speaker in the room.
  • The lightly slanted corners on the columns and satellites produce a large, horizontal dispersion angle so that an extraordinary sound can be enjoyed in every listening position.

Easy setup and installation

The slender standing columns are securely positioned on a massive aluminium base. The centre and the shorter columns have integrated wall mounts. It is also possible to place the centre on an included plate. Each loudspeaker is equipped with sturdy, gold-plated screw terminals. These can be used with cables with diameters up to 2.5 mm² .

Discover spatial sound

All speakers have the same acoustic equipment, which therefore produces the same sound quality and always guarantees an immersive surround sound experience. Even the central speaker has the same drivers. Only Teufel takes care of such details.

Heimkino Säulenlautsprecher LT 4 Teufel Center-Lautsprecher

An integrated class D amplifier supplies the system with 180 watts RMS, plenty of power for the 250 mm Klippel-optimised long-throw woofer. So equipped, the US 4110/1 SW can produce bass all the way down to a fulminating 30 Hz (-3 dB) with great power, precision and realism. Depending on the signal, the system switches from bone-rattling bass to a rich music foundation with ease. These preconditions make the US 4110/1 the perfect subwoofer for home cinema, music and gaming.

The connection panel on the back of the subwoofer also features various setting possibilities. In addition to a volume switch, the subwoofer has a high pass filter that can be freely set between 30 and 70 Hz and a phase switch. This allows the little US 4110/1 SW to produce an optimal performance in smaller rooms and acoustically difficult environments minus droning, booming or other unwanted effects. Thanks to an auto level regulator, the system can be adjusted to account for different levels from different AV receivers. The subwoofer communicates with the AV receiver via line-in.

A recessed control panel, angled power cord and down-firing woofer with double bass reflex vents make it possible to place the US 4110/1 SW directly against a wall or other surface. Room integration is made even easier with resonance damping feet that decouple vibrations from the floor.

The design of the US 4110/1 SW gives external expression to the system’s powerful yet harmonious performance. Clear lines and a high gloss front accentuate the system’s elegantly modest dimensions. The speaker is small enough to stow in a convenient place but attractive enough to display in any interior.

Easy integration

Each sleek column only takes up the equivalent of an A5 sheet of paper in terms of floor space, which makes the system easy to position, even in smaller rooms. The elegant aluminium exterior looks good in any setting.

Quality you can see as well as hear

The LT 4 loudspeakers are made entirely from brushed aluminium – a very expensive but stable material that is perfect for loudspeaker construction thanks to its noise-reducing qualities. Aluminium has the added advantage of giving the loudspeakers a subtle elegance that fits into any living room.

LT 4 "5.1-Set M" review of www.sat1.de
„…Teufels LT 4 macht ein Fest für die Ohren daraus und beeindruckt durch Dynamik und Spielfreude“
www.sat1.de 22.12.2015
„Schon rein äußerlich sind die schlanken Säulen, der massive Subwoofer und die Center Bar eine Freude durch schlankes Design, gebürstetes Aluminium und makellose Verarbeitung.“

„Durch die durchgehend überall gleiche Bestückung mit 19 mm Hochtöner und 80 mm Mittel- sowie 80 mm Tieftönern klingt die Anlage sehr homogen und kann auch kleinste Details punktgenau in den akustischen Raum projizieren. Ob es um typische Hollywood-Soundtracks mit großem Orchester geht oder serielle Explosionen in Actionfilmen, des Teufels LT 4 macht ein Fest für die Ohren daraus und beeindruckt durch Dynamik und Spielfreude. Das Set ist allerdings auch so gut, dass es Schwächen in der Quelle gnadenlos aufdeckt. Der Hörgenuss bei einer BluRay ist entsprechend hoch, ein YouTube-Stream klingt dagegen eher ärmlich. Das gilt ebenfalls für den Betrieb als Musikanlage. Der Unterschied von komprimierten MP3 Dateien oder Streams mit geringer Datendichte werden von den höllischen Säulen als minderwertig gegenüber der CD-Qualität entlarvt. Ganz großen Spaß macht das System aber im Zusammenspiel mit Gaming-Konsolen. Je nach Spiel ist die Ortung im Raum so gut, dass man das Monster hinter sich schnaufen hört und mit einer Drehung niederstrecken kann.“

„Als Fazit kann man mit Fug und Recht behaupten, dass in der Preisklasse [...] aktuell keine besseren Heimkino-Lautsprecher zu haben sind.“

SFT Magazin 06/2015
"With the Berliner’s current surround system, you get a piece of technology that flatters the eyes and ears in equal measure. The four floor-standing speakers, centre and subwoofer were adorned with extremely attractive aluminium accents as well as premium wood fibre plates and were designed to be as compact as possible.“

"When the speakers are properly set up, one really feels like one is at the centre of the action with movies and is treated to a very balanced and never too intrusive or energetic sound. The strong drivers even set imposing sonorous accents in the right places with music, the surround playback abilities consistently maintain enough breathing room.”

„... bietet viel Klang für `s Geld und überzeugt mit absolut makellosen Oberflächen und lupenreiner Verarbeitung“
www.lite-magazin.de 28.01.2015
„Dank zweier untenliegender Bassreflex-Öffnungen nebst kraftvoller und besonders effizienter Ansteuerung mittels moderner Class D-Endstufe, spielt der Subwoofer laut Hersteller runter bis 30 Hertz. Ein Wert, den normalerweise nur deutlich grössere Bassisten erreichen.“

„Der Center reproduziert klar verständliche und natürlich klingende Dialoge, während selbst kleinste Hintergrunddetails nicht untergehen. Ganz und gar nicht, denn selbige werden absolut gleichberechtigt zu Gehör geliefert, was uns eine überraschend authentische Raumabbildung im Frontbereich bietet. Hier macht sich dann auch schnell die üppige Bestückung der Front-Lautsprecher positiv bemerkbar, die ihren Teil zu dem nun phänomenal dargestellten Soundtrack beisteuern und im Zusammenspiel mit den agil zu Werke gehenden Rears das Wohnzimmer mit Atmosphäre und Hintergrundgeräuschen füllen. Die gesamte Performance stützt sich dabei auf das mehr als solide Bassfundament des US 4110, der auch inmitten diverser Schießereien, explodierender Autos und Häuser nie angestrengt wirkt oder aus der Puste gerät. Nein, denn hier hat Souveränität oberste Priorität. So soll das sein und so macht der Heimkinoabend mit Freunden erst richtig Spass.“

Fazit


„Das neue Teufel LT4 „5.1-Set M“ bietet viel Klang für `s Geld und überzeugt mit absolut makellosen Oberflächen und lupenreiner Verarbeitung. Das [...] Set besteht aus zwei schlanken Haupt- und drei kompakten Effektlautsprechern, die sich durch ihre sehr gute Detail- und Raumdarstellung auszeichnen. Der mächtige [...] Subwoofer unterstützt das Set und lässt es auch in etwas größeren Wohnzimmer souverän aufspielen.“

„... echte Empfehlung für Heimkino-Liebhaber“
Heimkino-Magazin 02-03/2015
„Im Zusammenspiel mit dem dazugehörigen Subwoofer liefert das LT4 M  im Akustiklabor  einen  recht  ausgewogenen  Frequenzgang  von  35 Hertz bis über 20 kHz bei erstaunlich geringen Verzerrungen.“

„Im Hörraum beweist besonders der kräftige Subwoofer seine Leistungsfähigkeit und kann druckvoll, sauber und beachtlich tief aufspielen.“

„[D]ie schlanken Alu-Säulen [spielen] [...] offen und neutral, auch überzeugt das tonal perfekte Zusammenspiel der identisch bestückten Alu-Säulen des Sets. Die räumliche Abbildung des Filmgeschehens gelingt dem LT4 hervorragend, Stimmen und Effekte lassen sich präzise orten. In den Disziplinen Maximalpegel und Dynamik sind den extrem kleinen Treibern natürlich physikalische Grenzen gesetzt, dennoch reicht das Set locker aus, um Hörraume bis 20 qm eindrucksvoll zu beschallen.“

„So hübsch kann Heimkino sein: Das 5.1-Surround-Set LT4 von Lautsprecher Teufel kann mit elegantem Design der schlanken Aluminium-Säulen begeistern und liefert zudem überzeugenden Filmsound. Dank der identischen Bestückung aller fünf Satelliten-Lautsprecher spielt das LT4 zudem wie aus einem Guss, dazu langt der kräftige Subwoofer des Sets im Basskeller beindruckend zu.“

LT 4 "5.1-Set M" review of SFT-Magazin
"The column setup has an exceptionally clear sound; the five tweeters, midrange drivers and woofers per speaker convey a consistently balanced tone that is never effusive."
SFT-Magazin 11|2014
"All components demonstrated top workmanship and are furnished with brushed aluminum [...] enclosures. The individual pieces are compactly built and take up as little space as possible.”

"The LT4 performed extraordinarily well in the listening test and can by all means compete with surround systems in higher price classes. The column setup has an exceptionally clear sound; the five tweeters, midrange drivers and woofers per speaker convey a consistently balanced tone that is never effusive. The spatial integration worked just as well. Thanks to the focused dispersion, one truly has the feeling of being in the center of the action with movies if the loudspeakers are properly placed.“

"[T]he subwoofer [conveys] the action in movies with imposing blasts of bass without pushing itself into the foreground. Instead, the driver sets deep accents in the right places and only use more of its180 watts when the sequences of the movie require it. In this way it’s possible for the center speaker to assert itself at all times so that dialogue is played back with a pleasant brilliance.”

"In addition to home cinema, the set is well suited to music listening. Here the subwoofer gives its fellow speakers enough sonic elbow room for a fine soundstage in the highs and midrange. The spatial impression is especially good with orchestral soundtracks when the rear channel speakers seem to surround the listener with music on all sides. And so we can attest to the LT 4 Set L’s outstanding talent for living room entertainment thanks to which it needn’t hide from much more expensive systems.”

"The homogeneity and precision evoked a higher price class, the 3-dimensionality as well."
video-Magazin 11|14
"With the new LT4, the developers created an elegant solution that not only impresses visually but awakens acoustic expectations as well.”

"The Berliners prefer a D’Appolito arrangement of their three-way drivers. This means: The tweeter measureing 1.9 cm across sits in the center between each of the two woofers and midrange drivers.”

"The set went about its business cleanly and virtuously [...]. The homogeneity and precision evoked a higher price class, the 3-dimensionality as well. [...] When it comes to dispersing sound, the LT4 was able to play up the advantages of having slender baffles on which the sound waves are barely able to get caught against, as well as the minimal directivity in the mid to upper range thanks to a smaller membrane diameter.”

"The LT4 is characterized by a stable sound image, excellent focus, and an especially transparent, deep-reaching dimensionality even when only stereo CDs are played. The bass came across with such purity and differentiation that it’s almost worth shelling out for a bass management system in a receiver for upping the ante with rich diaphragm-massaging sound in special effects and, if possible, saving it as a preset. With films and multi-channel music, the faultless collaboration of the almost identically constructed channel drivers for the front, center and surround made a good impression. Even the subwoofer contributed with feeling [...]."

    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?
    No.

    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.

    Information:
    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.

    Exception:
    • 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.


    When can I use the rear speakers as direct speakers?
    If you aren't able to position the speakers close to the wall as described above, you should use the them as direct speakers. For this purpose the rear switch should be tipped outwards. For use as direct speakers, the rear boxes should be set up to the left and right of the listening position - ideally at the same height, e.g. on a shelf or preferably on a base. If the speakers have to be set up so that they are much higher or lower, it may be advisable to align them to the listening point. For wall mounting it is best to use wall brackets that allow for vertical movement. When using the speakers in direct speaker mode, we recommend that the distance between the two rear speakers exceeds the listening position by 1m. But if you (have to) sit closer, please make sure that the front of the speaker is not pointing directly at you; instead, angle the speakers more into the room.
    Can I set up the set in a different way to that described?
    The recommended set-up information below represents the best possible arrangement for perfect multichannel playback in your home. Your available space, your partner or your furniture may not always allow you to arrange the speakers in the ideal manner. Try to meet as many of the requirements as possible.

    Modern AV Receivers offer numerous options for compensating electronically for any compromises in the set up. Generally speaking, the following rule always applies: you can always use our recommendations as a basis for experimenting with what works best for you, acoustically and optically. Let your ears (and eyes) decide!
    Der Subwoofer spielt nicht – was kann ich tun?
    1. Falls die Power-Diode nicht leuchtet:
    Tauschen Sie die neben dem Netzschalter befindliche Sicherung aus. Falls die Power-Diode danach nicht leuchtet, wenden Sie sich bitte an unseren Service. Falls die Power-Diode danach leuchtet, aber kein Ton zu vernehmen ist, verfahren Sie bitte wie unter Punkt 2. beschrieben.

    2. Falls die Power-Diode leuchtet:
    Drehen Sie den Pegelregler Level am Subwoofer auf »Minimum«, ziehen das Subwoofer-Cinchkabel am Verstärker ab, drehen Level vorsichtig hoch und berühren den Cinch-Heißleiter des Cinch-Kabels (innen) mit dem Finger. Ist nun ein Brummen oder Knacken zu hören, liegt der Fehler beim Receiver oder seinen Einstellungen. Bleibt der Subwoofer stumm, wenden Sie sich bitte an unseren Service.
    My subwoofer is humming. What can I do?
    This hum can be caused by the connected devices or disruptions in your electricity current. Please do a test to see which it is.

    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.
    Benötige ich für das Produkt noch einen separaten 5.1-Receiver?
    Nein. Der Subwoofer hat wichtige Receiver-Funktionen bereits integriert, z. B. 350 Watt-Verstärker, Radio, Analog- und Digitaleingänge, Dolby Digital/dts-Decoder, etc.
    Was signalisiert die blinkende, gelbe LED auf der Rückseite des Subwoofers?
    Die blinkende LED zeigt an, dass sich der Subwoofer im Stand-by Modus befindet.
    Wie stelle ich meinen US 4110/1 Subwoofer richtig ein: Lautstärkepegel ("Volume")?
    Die Lautstärke-Einstellung des Subwoofers wird bei Musik im Vergleich zum Heimkino je nach Aufnahmequalität und Abmischung geringfügig abweichend sein.
    Während bei effektstarken DVDs häufig ein massiver Tiefton-Anteil vorherrscht, ist bei Musik teilweise nicht der gewünschte Pegel zu vernehmen (insbesondere wenn das Set auf optimale DVD-Wiedergabe hin eingestellt worden ist).
    Hier ist vor allem der eigene Geschmack für das beste Kompromissverhältnis zwischen beiden Quellen wichtig. So finden Sie nach und nach die beste Lautstärke des Subwoofers heraus. Als Startpunkt ihrer Experimente empfehlen wir die
    Volume-Reglerstellung auf "2 Uhr".
    Will an active subwoofer only run in 5.1 mode or also in stereo mode?
    Thanks to the speaker set-up/bass management integrated in the home cinema receivers/amplifiers, the subwoofer functions in stereo, Dolby Surround and digital mode.

    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.
    Why doesn't my active subwoofer switch on automatically?
    Some AV Receivers/amplifiers issue the bass signals via the subwoofer pre-amplifier output so quietly that the subwoofer does not start automatically.

    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).
    How do I connect my fully active Teufel system to an AV Receiver?
    Although designed to be fully active, the Teufel set is also partially active in conjunction with an AV Receiver.

    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.

    Please note:
    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.
    What is a ground hum?
    The hum (50 Hz) comes from the 220 volt supply network and is caused by current power flows through the protective conductor. These so-called "ground hums" is caused when you connect two devices that are already grounded on the protective conductor (subwoofer) or the antennae cable (AV Receiver) to the subwoofer cable.

    Solution:
    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.
    Where is the optimal place for the subwoofer of my Lautsprecher Teufel Surround System in a 5.1/6.1/7.1 configuration?
    The location of a subwoofer with a recommended cut-off frequency of under/equal to 120 Hz can be freely selected and does not affect the other speakers.

    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.
    How do I determine the right phase setting of the subwoofer?
    By setting the phase, you can affect the point at which the membrane of the subwoofer bass speaker moves to the front. This setting makes it possible to optimally adjust the subwoofer to the satellites.

    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!
    What is the use of the on/off automatic switch ("Auto On/Off") of the active subwoofer?
    The On/Off switch is a power-saving standby switch. The switch must be set to "On" or "1" to activate the standby. The subwoofer is activated as soon as it receives a strong bass signal. After approx. ten to twenty minutes of no signal, or only after receiving a very weak signal, it automatically switches to the standby function.

    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.
    What happens to the power amplifiers of the subwoofer if I don't connect the satellites?
    As soon as the satellites are connected to the subwoofer and not to the AV Receiver/amplifier, the performance of the 6 or 8-channel power amplifier is distributed to the subwoofer and to the satellites.

    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.
    How can I connect an additional active subwoofer?
    If your receiver has only one subwoofer output ("Sub Out"), you only need a monocinch cable, which is then connected from the receiver to the "Sub In" of the subwoofer. With two subwoofer outputs, you can order a so-called Y-adapter from the Teufel accessories page, which has a cinch plug on one side and two cinch (RCA) sockets on the other. Connect the plug to the subwoofer "Pre Out" on the AV receiver/amplifier and connect the mono cinch cable to the two subwoofers.

    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.
    How is the wattage of a subwoofer with respect to the sine wave and pulse/music performance?
    Mono 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.

    Multi-channel subwoofer:

    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).
    What are the volume switches for?
    The sound of the speaker always depends on the room where it is located.

    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.
    What is room resonance frequency?
    Room resonance frequency (other terms: room modes, standing waves, resonance frequency) is the frequency at which the vibrations of a voice, a musical instrument or a signal played back over the hi-fi/home cinema system is amplified unnaturally, because the vibrations build up between the walls as well as the floor and ceiling.

    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.

    Phenomena of resonance frequencies:

    • 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.
    The RAMPA insert at the bottom of the speaker sometimes is turned out with the tamping screw. What can I do about that?
    Unscrew the tamping screw from the Rampa insert and screw the Rampa insert back into the bottom of the speaker.
