Berlin's bestseller

For years, the Ultima series has stood for a very good price to performance ratio. You won't get so much sound for such a good price anywhere else. Featuring superior audio technologies, the Ultima speakers deliver a perfectly balanced playback and are suitable for rock, pop, electro, classical and jazz music, as well as gaming and of course films. The new Ultima speakers are recognisable by the logo above the tweeter. They are the successor to the Ultima Mk2 series.

Compatible with all AV receivers

Thanks to their high efficiency, the Ultima speakers work together with any AV receiver. If you want to provide sound for rooms over 20 m², we recommend AV receivers from around the 400 € mark.

Developed in Berlin

The complete development of the Ultima series, as well as all other speaker series, takes place here in Berlin in our laboratories and special anechoic audio rooms. Optimisation and refinement has been carried out over the years in close cooperation with our design team. Of course, customer feedback continues to act as a crucial factor in the further development of all our products.

Building the first prototype

    Tweeter with phase plug and waveguide

    The phase plug and waveguide built into the tweeter are unusual features for a product in this price range. They create even crisper sound precision in the high-frequency range.

    Phase plug
    Phase plug for avoidance of phase shift cancellations resulting in improved transparency and directional behaviour of higher frequencies.
    Teufel Stereo-Lautsprecher Ultima 40 Mk3
    Waveguide for a very precise location of individual sound sources and precise stage imaging of all instruments and voices.

    Kevlar mid-range driver with phase plug

    The mid-range driver is not only particularly large, but also has a phase plug. The result is very good speech intelligibility and a particularly warm, natural mid-range. This also expands the listening area in which listeners enjoy optimum sound.

    Double bass – a real Teufel in every respect

    Especially if you're looking for full bass without a subwoofer, this full-range speaker is the right choice. Two large 165 mm fibreglass woofers provide a particularly precise low-frequency reproduction. The long stroke ensures distortion-free playback even at high levels. You don't need an additional subwoofer.

    Design and materials

    No shortcuts were taken when it came to optimising our Ultima speakers. Here are the highlights of the new range:

    Modern, timeless design

    Teufel Stereo-Lautsprecher Ultima 40 Mk3

    The solid, gently curved MDF housing is the result of more than 30 years of Teufel experience and modern speaker technology.

      3-way system

      The foundation for good sound lies in the design of the 3-way system, which has been further developed and improved over many years. The drivers work together in harmony across all frequency ranges, resulting in an extremely smooth and clear sound reproduction.

      Close-fitting driver for a vivid, balanced sound reproduction

      Two large bass reflex tubes with a trumpet tube attachment minimise any current noise - no other manufacturer makes this much effort.

        First class speakers
        I have had these speakers on my wish list for a while, now I have them and I am thrilled.
        (automatically translated *)
        From ordering to delivery to enjoying the good sound, everything was perfect. The workmanship and the sound of the speakers are very good. If you only want to hear the bass and not feel it, you will be satisfied. For the rest, you just need a sub to go with it. Conclusion: I give it a very clear buy recommendation.
        Klasse Boxen mit hohem WAF (Wife acceptance factor)
        After two years without, I was looking for floorstanding speakers that would match our white furniture and still offer a good sound experience. In addition, the covers had to be sturdy enough so that my children (4 7) couldn't "accidentally" see how deep you could press a finger into the membrane. Since I can still call a passable Marantz amplifier my own, I decided on the Ultima 40 without the Active part. Why the high WAF? 1. hard to beat price-performance ratio.2. unagitated design. In white to match our living room.3. Sturdy covers as a child safety lockI am extremely satisfied with the sound, the connection and the look. I'm not someone who can judge this more accurately, but I don't hear any hissing or other annoying "background noise".The delivery of two speakers on two consecutive days was a little unnecessary, but acceptable.Unfortunately, it took me quite a lot of research to find out something about the stability of the box covers. Maybe you could include a picture on the website.Conclusion: I like my new speakers and my wife is satisfied. What more could you want?
        Beautiful to look at and play in fact after hearing the speakers play and appreciate the column I decided to replace all the rest of my system taking the two satellites the central and not least the sub woofer are magnificent top finishes I was satisfied with everything I can not do anything but recommend them to everyone last 40 Top
        The speakers exceed my expectations in terms of clarity in the highs and mids as well as bass many times over. I am super satisfied.

        I am thrilled
        I would not have expected such a sound for the price. Crystal clear highs and optimal bass.

        Top speakers! Price performance simply top!Always happy to do it again!Keep it up!!!! ❤️

        The right choice
        The speakers made an extremely valuable and well-made impression as soon as they were unpacked - heavy and solid, as it should be. They were placed to the left and right of an average wall unit opposite the sofa in a room of about 20m². The upstream amplifier is a self-made tube power amplifier with about 70W sine power per channel. In terms of sound, they are well tuned in my opinion. Powerful with strong bass and a clear midrange/treble for electronic beats or rock sounds and pleasantly mellow for quiet music of any kind.The delivery is well and securely packed in two individual packages, which makes transport easier. However, I would like to express some criticism here, which is not enough for a "point deduction". To protect against moisture, the generally known moisture absorbers travel in the box. Unfortunately, there were 4 of them in one of the two speakers and none at all in the other. In my case, this did not lead to any damage, but it is certainly not the intention of the inventor. The documents supplied, such as operating instructions and safety instructions, were in both speakers, some even shrink-wrapped and in many languages. The double version makes little sense for loudspeakers that are only available as a pair, and shrink-wrapping is simply not necessary. In addition, one could limit oneself to the respective national language or perhaps already give the option of choosing a language for the documents during the ordering process. All in all, the speakers were the right choice and I can recommend them.
