Fill your room with sound, not audio equipment

The space constraints of many modern homes require innovative sound solutions. Many people want to fill their room with sound but don’t want all the gear that goes with a traditional stereo system. For this reason, we developed the Ultima 40 Active, two beautiful tower speakers with integrated amplification. Germany’s most-purchased stereo speakers now come in a fully active version.

When it comes to sound, the Ultima 40 Active uses all the same high-quality audio components as its passive counterpart. The only difference between the original Ultima 40 and its active counterpart is where the system draws its power. With the Ultima 40 Active, power comes from within.

Sounds all good, but where is the subwoofer?

In an Ultima 40 Active stereo pair, all required amplification is tucked away inside the active speaker. An integrated class D amplifier delivers 100 watts per channel – more than enough power for room-filling sound.

Includes everything you’d expect from a complete stereo system

The Ultima 40 Active’s connection panel offers space for additional source devices like game consoles or CD, record and MP3 players via TOSLINK or stereo cinch input. An equalizer allows you to adjust the sound to your personal preferences.

Music streaming with Bluetooth – check!

The Ultima 40 Active is even equipped for Bluetooth streaming. Play back all the music from your favourite audio apps or the files stored on your phone from the comfort of your sofa.

Double bass

Low frequencies are handled by two parallel 165 mm fibreglass/cellulose drivers. Thanks to a  cabinet volume of 52 litres and double reflex vent, the Ultima 40 Mk2 produces fantastic bass down to 45 Hz. A large mid-range driver (165 mm) ensures great speech intelligibility, and the two 25 mm tweeters handle the top ranges brilliantly.

Developed in Berlin

When it comes to sound, Teufel leaves nothing to chance. The tiniest imperfections in the Ultima 40's driver action were identified per laser technology and corrected. The result is amazing true-to-source sound with all genres of music.

High-quality materials

Solid wooden cabinets with softly rounded corners contain advanced audio technology, the product of Teufel's over 30 years' experience in loudspeaker construction. Rock, jazz or electronic: Whatever you play on these speakers is rendered with incredible transparency and livliness.
Display the Ultima 40 Mk2 with or without grilles. The attractive drivers are one of the stereo towers' main highlights.

3-way system

Over one meter tall, each tower features a 3-way speaker system. Above two 165 mm bass woofers is a 165 mm Kevlar/fiberglass midrange driver in a separate resonating chamber. This premium driver covers the range from 650 Hz to 26000 Hz. A phase plug enhances the system's thermal load capacity and prevents phase shifts from muting any of the playback. A 25 mm tweeter completes the offering with a brilliant but never-shrill treble.

The new subwoofer

The S 6000 SW is Teufel’s premium universal subwoofer model designed and developed in Berlin. The active sub is powered by an extremely low-noise amplifier with plenty of setting options including volume, phase switch, auto level switch and high pass filter. A recessed amplifier makes it possible to place the subwoofer directly against the wall.
The S 6000 SW employs a 300 mm woofer to push the low end all the way down to 28 Hz. Teufel’s proprietary Air Stream Bass technology uses a specially constructed air vent to minimized wind noise at high levels.

Ultima 40 Active Club Edition (2017) review of www.av-magazin.de
"Striking, grandiose sound..."
www.av-magazin.de 29.11.2016
"With power and character, clear and full of volume without a trace of pushiness in either the vocals or the instruments. With movies [...], every fine nuance can be discerned as easily as powerful surges of sound.”

"The viewer is positively drawn into the movies[...].  Even James Bond’s Spectre shines on all sides with the Ultima 40 Active. The voices that are so full of character [...] are reproduced by the speakers just as well as screeching tyres or the threatening sound of helicopter blades. One is right in the action instead of just a bystander!”

"The Ultima 40 Active is absolutely perfect gear for every party. Thanks to my 16-year-old son, I know that both speakers [...] can animate dancers to the finest techno shuffle – via Bluetooth or CD player. On a side note, I was wonderfully entertained by the Three Tenors singling “La Donna e Mobile” while making pizza, even though I was not positioned in the ideal stereo triangle. Striking, grandiose sound for (nearly) all occasions.”

Ultima 40 Active Club Edition (2017) review of AUDIO
"The drivers reproduce Bobby Kimbal’s "Too Far Behind“ with such a punchy and beautiful stereo panorama that we found ourselves moving to the beat."
AUDIO 02|2017
"The drivers reproduce Bobby Kimbal’s "Too Far Behind“ with such a punchy and beautiful stereo panorama that we found ourselves moving to the beat. But the system is capable of more. We wanted a harder sound and put on some classic rock. The speaker really flexed its muscles with “Visibility Zero” from the current Kansas album. The good ol’ Hammond organ skilfully asserted itself in the intro and the vocal harmonies in the chorus were goose bump inducing. Can the system handle more? How about some Panzerballett! Turned up all the way, the jazz metal group ploughed through the room with a good amount of power and depth. The powerful class D amplifier showed itself to be fearless and really went to work. Great stuff.”

Conclusion:


"…Teufel really did good work with the amplifier, which gives the tower speakers a good amount of power. The real highlight, however, is the connection options. These open new possibilities, especially in regard to home cinema use.”

Ultima 40 Active Club Edition (2017) review of www.areadvd.de
"The Berlin transducers really showed what they’re capable of and delivered a brilliant performance..."
www.areadvd.de 21.12.2016
"With the Blu-ray disc, “Avengers“, we skipped to the parts “The Invasion Begins“ and “The War“. The Ultima 40 Active showed us that it definitely has enough power and dynamics it has at its disposal to shine in the area of film sound. The moment when the reactor opens the black hole is reproduced with solid force and good 3-dimensionality. The following dialog between Stark and Loki in the cavernous room in Stark’s Skyscraper was presented with very well-balanced vocals. The punches and Iron Man’s jump through the closed window proved that both speakers are possessed of considerable qualities.”

"We switched to music and tested the Ultima 40 Active with “What is Love 2016“ by Lost Frequencies. The master and slave speakers were really impressive: The bass showed itself to be truly hard with good impulse fidelity. The Berlin transducers really showed what they’re capable of and delivered a brilliant performance unlike any other part of our test. Above this, the singer’s vocals were well separated from the drivers. The Ultima speakers offer an all-around first-class performance here.”

"As if an outstanding price / performance ratio, sound that is far above average and great looks weren’t enough"
www.lite-magazin.de 15.12.2016
"The Ultima 40 from Teufel rightly deserves an excellent reputation, which will now be even further enhanced. As if an outstanding price / performance ratio, sound that is far above average and great looks weren’t enough, Teufel has equipped the active tower speakers with an HDMI input as well, thereby rendering them the perfect tools for use in hi-fi and home cinema. In addition, the practical plug-&-play characteristic is a good reason for hi-fi newbies who want a full system to buy the speakers. With the Ultima 40 Aktiv, nothing stands in their way, thanks to the added incentive of an extremely attractive price.”

Kann ich Spikes an die Ultima 40 Mk2 montieren?
Ja. Verwenden Sie dazu unsere Satelliten-Spikes. Auf der Unterseite der Lautsprecher-Bodenplatte befinden sich bereits entsprechende Gewindebohrungen.
Was für Lautsprecherkabel empfiehlt Teufel?
Wir empfehlen Ihnen Lautsprecherkabel mit einer Querschnittsfläche von mindestens 2,5 mm² bei größeren Längen auch 4 mm². Achten Sie darauf, dass linkes und rechtes Kabel immer gleich lang sind.
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.
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.
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.
