Overview of our technologies

Downfire
Premium speakers

Quality you can trust: The Ultima 20 are among the best bookshelf speakers in their price class. Our developers in Berlin made sure this stereo pair has the best-possible sound thanks to the following:

  • Large 25 mm tweeters for a silky, soft treble
  • Large 165 mm midrange drivers with phase plug produce balanced, evenly dispersed sound
  • Trumpet bass reflex vents eliminate wind noise and chuffing for deep, clean bass
  • Klippel-optimized drivers ensure an incredibly balanced frequency response

Each driver has been optimized by first-class Klippel technology – a first for speakers in this price class. This precision calibration technology allows the Ultima 20 to produce linear and balanced playback. Bass reflex ports with trumpet vents enhance the bass without wind noise. Well-braced wooden enclosures minimize vibrations resulting in a very clean sound.

Established, universal, timeless

The Ultima 20 Mk2 scores points on style with harmoniously rounded edges, compact dimensions, and cleverly accented drivers – a self-confident look sure to enhance any interior. The speakers can be seamlessly integrated into any home, fitting easily on either a shelf, wall, or floor stand.

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.

A centre with a rich, full sound

Equipped with 2 midrange drivers in a D'Appolito Array, the centre produces a full and powerful sound. Dialogue in games, television shows and movies is rendered clearly and distinctly thanks to the centre’s strong midrange. You’ll understand every word, even at lower volume levels.

The US 2110/1 SW is a powerful active subwoofer

Weighing in at over 20 kg with a 45 litre volume, the US 2110/1 has what it takes to deliver extremely powerful and deep bass playback. The integrated 125 watt amplifier drives a large 250 mm woofer down to 38 Hz (-3 dB) for rich, punchy and undistorted bass with music, home cinema and gaming.

Sleek, high-gloss elements, rounded corners and a slender shape allows the US 2110/1 to blend in to any interior. Requiring a minimum of space, it’s easy to place.

The downward-firing bass reflex port and angled mains plug make it easy to place the speaker along a wall. Four resonance damping feet give the system a stable position and decouple vibrations from the floor.

The back panel includes a mono cinch input for connecting to a home cinema AV receiver as well as volume control and slide switch for regulating phase.

An auto level switch with three stages makes it easy to optimally adjust to the output level from various source devices, allowing the subwoofer to seamlessly switch between devices. An integrated limiter protects the system from overload and distortion.

Mono-Subwoofer US 2110/1 SW
A 20 kg bass cabinet creates the ideal conditions for the powerful integrated amplifier (125 watt rms power) and a larger than average 250 mm diameter woofer.

Teufel's legendary subwoofer expertise give you a 40 Hz (-3 dB) low end for full-bodied and accurate bass. Music, home theater and games - everything sounds deep and rich.

Rounded edges, slim design and a glossy finish make this subwoofer discrete and elegant. Minimal space requirements mean it can be placed anywhere in your interior.

The down-firing bass reflex principle and the angled, recessed plug allow the subwoofer to be position directly on a wall; four resonance damping feet ensure secure footing and decoupling from the floor.

The RCA connectors for a home theater AV receiver are on the rear, along with the volume control and a phase slide switch.
A three-level auto-switch ensures optimum output levels on the various devices. This ensures the subwoofer is always perfectly in sync with the rest of the system. An internal limiter protects against overloading and distortion.

The U.S. 2110/1 SW is only available with Teufel speaker sets.

Ultima 40 Surround "5.1-Set" (2017) review of AV-Magazin
Ultima 40 Surround "5.1-Set" (2017) review of AV-Magazin Ultima 40 Surround "5.1-Set" (2017) review of AV-Magazin
“With the Ultima 40 Surround ‘5.1 Set,' Teufel presents another example of a great price/performance ratio."
AV-Magazin 14.11.2016
“The Ultima 40 Surround ‘5.1 Set’ consists of 2 standing speakers, 2 small compact speakers, a centre, and a subwoofer. [...] The front left and right surround positions are filled by two standing speakers, the UL 40 MK2s, that have already won many test awards. [...] UL 20 Mk2 bookshelf speakers are used for the rear channels. The centre speaker UL 40 C Mk2 – so important for movie dialogue – can be easily wall mounted thanks to handy keyhole brackets on the back.”

“A 3-way system is responsible for sound transducing in the front loudspeakers. This is comprised of a 165 mm bass driver, a 165 mm midrange driver, and a 25 mm tweeter. The latter […], along with the midrange drivers, are used in all Ultima loudspeakers. This uniform construction in the high and mid ranges allows Teufel to achieve a balanced tonal character as well as a homogenous surround sound.”

“The centre speaker is constructed according to a so-called D’Appolito system whereby the tweeter is positioned between two midrange drivers . The use of double midrange cones ensures the powerful reproduction of speech and vocals. In the low range, the subwoofer makes use of an imposing 250 mm driver. This is powered by a 200 watt digital amplifier [...]"

“The Ultima set immediately won us over during the acoustic test. The surround sound is excellent thanks to the use of the uniform components for the midrange. A thick and cohesive atmosphere forms between the front and back speakers that transforms the viewer into a participant in the action. [...] On top of this, the Teufel speakers have a pleasantly broad and dynamic sound reproduction.

This is especially noticeable with musical selections.”

Conclusion
“With the Ulitma 40 Surround ‘5.1 Set,‘ Teufel presents another example of a great price/performance ratio. For just € 1,000, home cinema fans get a powerful set of loudspeakers that evince an excellent dynamic, high resolution, and impressive surround sound with all types of sound. This is what true cinema heroes look like.”

"A high-class 5.1 sound system that impresses across the board"
www.soundsysem-ratgeber.com 28.06.2016
 "In short, absolute madness. Even the finest sounds are reproduced in a crystal-clear way and ensure that goosebump feeling for so many movie moments. Two parallel 165mm bass drivers provide a double bass layer, which you cannot only hear but also really feel. With two mid-range speakers and D'Appolito (midwoofer-tweeter-midwoofer) arrangement, the central loudspeaker delivers a powerful, distortion-free sound for high-quality speech intelligibility and playback. Overall, the Teufel Ultima 40 System offers a well-rounded, and above all tight, sound and the listener feels as though they are really a part of the action. A realistic cinema-feeling is guaranteed, that much is sure."

Conclusion:

"The Teufel Ultima 40 is a high-class 5.1 sound system that impresses across the board. Here you have a real masterpiece in terms of home cinema sound - you'll be thrilled."

Ultima 40 Surround "5.1-Set" (2017) review of www.areadvd.de
"Once again, Teufel shows how it’s done: Affordable, but acoustically first-class, the Ultima 40 mk2 “5.1 Set” is recommended for movie soundtracks and music."
www.areadvd.de 25.11.2016
"The reasonably priced floorstanding speaker, the Ultima 40 Mk2, was a big success for Teufel. Many stereo fans who value excellent sound at a small price are happy with this loudspeaker. Now the time has come to expand the Ultima 40 Mk2’s area of operation. Teufel therefore offers a 5.1 surround set. [...] The entire set has the "typically Teufel“ price of  999 [...]

The floorstanding speakers prove themselves to be bass-happy, and when the active subwoofer joins in, massive bass is guaranteed. The US 2110’s [the subwoofer] depth is excellent considering the price and size and when the "double bass“ function on the front speakers and subwoofer is selected on the menu of the A/V receiver, the bass range is powerfully reproduced, but not just with power – it is also precise. [...]

A characteristic of the Ultima 5.1 system is the high degree of balance that enables a complete, full sound. The listener has the impression of being immersed in sound instead of being on the outside looking in. [...] As the first song gets started, the Ultima 40 5.1 ensemble lets loose enormous dynamics that engage the entire room and ensure an intense listening experience. [...] For film sound, we listened to “Mission Impossible: The Ghost Protocol” (Dolby TrueHD). Even the Paramount trailer at the very beginning evinced an enormous bass power combined with excellent dimensionality. [...] Through it all, the musical score was rendered with a lively extensivity. A few scenes later and Hunt’s team headed to Dubai in a Landrover. The musical score has a lot of power and fluency, the voices of the team members within the Landrover were perfectly expressed. The Ultima 40 5.1 system manages the evasive maneuvers with screeching tires as the vehicle avoid camels as expertly as Hunt. [...]

The passive components also avail themselves well: The pinging of a smartphone that localizes the sender can be clearly heard, the grains of sand that whirl through the room pass by the listener, and as Hunt hits against the windshield of the BMW X3, the effect disperses an enormous amount of energy. The chase scene between Hunt in the BMW convertible and Witrom (the disguised Hendricks) in the X3 is a pure joy for every action fan: Intense, multi-faceted effects, wide-ranging total playback, and very deep bass from the active subwoofer. One can therefore say that authentic home cinema listening pleasure is also possible with the Ultima 40 5.1 package.

Conclusion

Yet another reference system in this price class? "How is it possible?" many will ask, yet the reason is simple: Teufel completely understands what buyers want and consistently meets the demands of many users.  One can therefore conclude the following: The Teufel sound hits hard again with a mature 5.1 set with floorstanding speakers and truly large bookshelf speakers and a perfectly tuned centre as well as a powerful subwoofer that is a pure joy with multichannel music and film soundtracks. Visually, the Ultima has a very pleasant design and the set is well made. The sound is absolutely outstanding: Raw and fine dynamics are reproduced way beyond the average for this price class. The system also has stable levels, a strong bass, and a room-filling sound. Once again, Teufel shows how it’s done: Affordable, but acoustically first-class, the Ultima 40 mk2 “5.1 Set” is recommended for movie soundtracks and music.”

Ultima 40 Surround "5.1-Set" (2017) review of audiovision
"Teufel [offers] a mature home cinema set that scores points thanks to its dynamic yet unintrusive playback that also cuts a fine figure with bass.”
audiovision 05|2014
"The sound from this set is immediately enjoyable thanks to its very pleasant, well-rounded character which makes it possible to listen without fatigue - even over longer periods of time. The Teufel set, however, doesn’t carry its feel-good ambitions to the extent that details force their way to the front or disappear.”

"[E]ven taut levels [are] no problem, but rather only add another fun factor, because the combined membrane surface of the front speakers and subwoofer will cause the walls of your stomach to vibrate and cause the glasses in your cabinet to come crashing down.“

"Multichannel music is also fun with the Teufel set. Played with power, “Away from the Sun” from 3 Doors Down was wonderfully dynamic, without any aggression being added to the edgy sound of the rock music. The Teufel set approaches the levels of live music without overly exerting itself. Even at low volumes, […], the set aquitted itself with a clean, 3-dimensional sound image and dynamic playback.“

Ultima 40 Surround "5.1-Set" (2017) review of Heimkino
"The Ultima Surround Set is a sonic power house, looks great, and offers a sound that can hardly be matched in this price class – highlight!"
Heimkino 2-3|2014
[...] The success of both [stereo speaker] models the Ultima 40 Mk2 and the Ultima 20 Mk2 led the Berlin loudspeaker specialists to construct this complete multichannel system. It’s been expanded to include a precisely optimized centre loudspeaker and a potent active subwoofer. [...] The Berliners are asking € 999 for the 5.1 multichannel system for which the usual 12 year guarantee applies.

Ultima 40 Mk2 floor-standing speakers

Both of the main speakers are full-fledged standing models that radiate maximum sound from their slender enclosures. Thanks to powerful bass drivers that Teufel optimized with Klippel measurements and a well-tuned bass reflex enclosure, the loudspeakers are able to produce even more sound than their predecessors. [...]

Rear speakers UL 20 Mk2 and centre speaker UL 40 C Mk2

The compact bookshelf speakers are tried and tested models [...] Teufel’s developers placed a large bass reflex vent on the back as well as a stable single wiring loudspeaker terminal. Stand feet for the UL 20 Mk2 that bring the bookshelf speakers to ear height can be purchased separately.

US 2110/1 SW Subwoofer

The roughly 35 cm deep and wide very elegant subwoofer packs a generous 45 liter volume in a tall enclosure made from stable MDF. Rounded corners and high gloss elements add a touch of elegance to the subwoofer equipped with a 250 mm high-excursion paper membrane driver and a 200 watt high-performance active module. Thanks to the downfire principle with a bass reflex vent located on the bottom and the active module integrated into the surface with angled, in-built power adapter, the US 2 110/1 SW can be positioned directly against the wall. The four stand feet made from resonance damping material ensure an adequate distance to the floor and secure positioning. [...]

In our home cinema test room, both bass reflex floor-standing speakers in a stereo setup had a very balanced sound that was much more impressive than its price class would lead one to expect. [...] The Ultima 40 Mk2‘s infectiously enjoyable playback makes every type of music a pleasure to listen to. We supplemented the main loudspeakers with the centre and rear speakers that come with the set and placed the subwoofer between both front speakers and slightly off centre. [...] Voices and instruments could be precisely localized, movies and sound effects were very vivid. [...] We have seldom hear a system in this price class with such balanced and full-fledged attributes. [...]

Conclusion

It’s almost uncanny how the manufacturer Teufel always manages to present really excellent loudspeakers at phenomenally low prices. The Ultima Surround Set is a sonic power house, looks great, and offers a sound that can hardly be matched in this price class – highlight!

Help regarding this product
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.
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.
