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.
The first sketches
Evaluation of acoustic measurements
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.

Waveguide
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:
High-gloss tweeter and matte speaker cabinet
Easy to clean finish with scratch-resistant surface
High-quality fabric mesh with revolving bevel - the frequency response is only minimally affected
Modern, timeless design
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.

Speaker adeguati
Product meets my expectations, good bass and all. Perhaps if there had also been a wood-coloured version it would have been the best.

Klank
The sound is great and the speakers are also nice in white! Despite this, I returned them because they were too prominent in our interior.

Fantastic
Now I have been using it for more than 14 days and in one word: fantastic, what a sound, perfectly balanced high-mid and low tones, whether I am listening to classical music, metal or hardstyle.
