Award-winning tower speakers

With the Ultima 40 floor-standing speakers, you get a piece of Berlin in your home and enjoy a wide range of music, from electro to opera to rock. It's not for nothing that the Ultima 40 are Germany's bestselling stand-alone loudspeakers.

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.

Stereo-Lautsprecher Ultima 40 Mk2
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.

Shindig! Issue #68
"Back in issue #64 we reviewed German hi-fi manufacturer Teufel's excellent Bluetooth headphones, the MOVE BT and the MUTE BT... Their equally impressive Kombo 62 stereo system bundles the brand's popular Ultima 40 tower speakers -- which pack a punch with deep bass, silky highs and a decent mid-range -- with the Kombo 62 receiver.

Packing a CD player, DAB/FM radio and Bluetooth streaming facilities into the body of a tidy looking reto-ish amp, its no-frills appearance mask the plethora of delights that sit inside. We've coupled this up with a Project Tube Box analogue pre-amp and an old Technics Sl 1610 MK2 record deck to create the very best of THEN and NOW. The pre-amp's valves work well with the receiver, whilst the colossal speakers ably pump out the crackly old vinyl and new platters alike.... Bluetooth streaming with aptX is impressive and a very nice touch. Streaming lossless from the Mac comes pretty close to CD quality. You can also easily connect to your phone, tablet and most auxiliary devices.

The Kombo is a nice contemporary upgrade sound system for anyone seeking what is essentially an all in one box (bar deck) for your 2017 listening needs. Vinyl, CDs, digital files, radio... It can do the lot."

Kombo 62 Power Edition review of hifitest.de
"With its Kombo 62 complete set, Teufel offers a great deal for just a little under 1,000 Euro – you won’t get more music for this price anywhere else."
hifitest.de 24.3.2017
"No one needs more than that offered by Teufel’s Kombo 62 to enjoy music. The system’s CD receiver may be visually restrained, but the inside contains the most modern technology and an extensive feature set. Behind the classic façade is a CD drive, Bluetooth with aptX and NFC, USB playback, DAB+ radio and FM receiver. Added to this are two powerful amplification channels with a 200-watt total power performance that can easily deal with each of the Ultima 40 Mk2 tower speakers. We are very familiar with them as they were enthusiastically received by our listeners in a test from our June 2012 edition.”

"Our 1,000 Euro test combo impressed those in the listening room from the start and revealed itself to be an uncomplicated system. Thanks to its powerful amplifier, the CD receiver harmonized wonderfully with the tower speakers. In the low end, the Ultimas pushed for all their worth: The deep bass is rich, rolls beautifully and arrives at the listener with a good amount of pressure. If the speakers are positioned with enough distance between the back and side walls, the bass remains tight and precise without playing too much in the foreground.”

"With its Kombo 62 complete set, Teufel offers a great deal for just a little under 1,000 Euro – you won’t get more music for this price anywhere else. The CD receiver’s performance was especially impressive. This scored points with its enormous power, good sound and great features as well as first class user friendliness. Also included are the Ultima 40 Mk2 tower speakers which we know to be excellent and which perfectly harmonize with the electronic corner stone.”

Kombo 62 Power Edition review of www.audio-check.org
"In this case, a product was brought to the market that combines excellent sound, functionality and design.”
www.audio-check.org 17.10.2016
"Without question, the Kombo 62’s sound quality can be characterised as exceptional. The Ultima 40 tower speakers do an excellent job: The treble, midrange and bass work very harmoniously together. All the while, a rich bass is produced that can be regulated to suit the listeners’ musical tastes. As expected, no tones stand out at high volumes and the speakers stand up to continuous periods of high levels without incurring damage.

Teufel recommends the included UL 40 MK2 tower speakers for rooms up to 35 m². But we think the performance is suitable for much larger rooms.”

Conclusion:
"At the end of the day, we can say that the development of the Kombo 62 was well executed. It’s a top device that scores points with its sound and elegant look.”

"In this case, a product was brought to the market that combines excellent sound, functionality and design.”

Kombo 62 Power Edition review of SFT Magazin
"Whether a subtle reverberation of a string or a horn player’s intake of breath, the system rewards attentive and conscious listening with an immense tactfulness."
SFT Magazin 10/2016
"When it comes to sound quality [...], it hit all the right notes. During the first test with classical music from a CD, the receiver brought forth fine details that are often lost in the entanglement of frequencies. Whether a subtle reverberation of a string or a horn player’s intake of breath, the system rewards attentive and conscious listening with an immense tactfulness. On the flip side, the trio has no problem with hard guitar riffs or hot hip hop bass. Also interesting: If instead of the finest CD delicacies one feeds the receiver with lower resolution streaming material, the quality loss is limited. AptX codec technology has become so advanced that a well-defined sound is even possible via the wireless transmission option.”

"With clear and precise imaging and a charismatic presentation, the set caters to the sort of listeners who are looking for more than background music"
Area DVD 23.09.2016
 “The team that Teufel put together, the Kombo 62 receiver and two tower speakers from the Ultima series, harmonize beautifully together. One can’t help but sit up and take notice when playback starts. The Berlin ensemble immediately succeeds in establishing interest in the room with a well-structured, deep and expansive 3-dimensionality.”

"With clear and precise imaging and a charismatic presentation, the set caters to the sort of listeners who are looking for more than background music, those who would rather listen to music consciously and with certain expectations.”

Conclusion

"A clean performance: The Kombo 62 2.0 stereo set has the ability to spontaneously awaken enthusiasm. But even when one [...] gives the set a closer look and listen, the strong performance is to be praised. The receiver looks good, displays excellent workmanship (inside and out) and has very strong levels."

"The Ultima 40 Mk2 was already known to us as a very well made product, and the model we tested here likewise impressed with a homogenous, cultivated and, at the same time, lively sound reproduction as well as a chic look with a high-quality base and pleasantly rounded enclosure edges.”

Kombo 62 Power Edition review of AV Magazin
"The strings were reproduced with full details, while the timpani sounded dynamic, agile and powerful."
AV Magazin 20.09.2016
"After feeding the CD tray Prokofiev’s "Romeo and Juliett“ by Telarc, it wasn’t long before we were in awe. The Teufel combination goes about its business with a broad, full-bodied and highly dynamic aspect. The strings were reproduced with full details, while the timpani sounded dynamic, agile and powerful. The fantastic singing, as in the movie "Waiting to Exhale,“ was no exception. Whitney Houston and CeCE Winan’s vocals sounded very authentic as the midrange driver reproduced her soulful & exceptional voice neutrally and with extreme plasticity. In the bass range, both Teufel speakers controlled the bass in the listening room which sounded at turns earthy, warm, punchy and powerful. At the end of the day, we were thrilled with the overall acoustic qualities of the Ultima tower speakers that can be recommended completely and without hesitation for music, movies and TV sound.”

Conclusion:

"With the Kombo 62 set, Teufel presents a complete high-performance hi-fi system that expertly strikes a balance between multiple sources, price/performance and sound quality. Thanks to the solid amplifier and loudspeaker technology, the customer truly gets a sensible listening experience at a fair price.”

Help regarding this product
My Bluetooth speaker produces a lesser quality sound with my Windows PC or laptop.
It could be that the speaker is connected as a device with speakerphone function. Please go to: settings menu > devices and printer > BOOMSTER (or other Bluetooth device). Right click on the device and remove the check mark next to the “speakerphone” option.
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.
