For smaller rooms up to 20 m², and tighter budgets, the Ultima 20 is the perfect choice. With the same sound technologies of its bigger sibling, the Ultima 40, these bookshelf speakers really prove themselves when it comes to sound - whether you place them on a shelf, stands or on the wall.
Key advantages at a glance
A pair of high-end Hi-Fi bookshelf speakers from Europe's most popular speaker series
High sound enjoyment for music, film sound and games in smaller rooms
New: tweeter with phase plug, optimised sound dispersion, fine tuning across all components, more balanced sound, improved workmanship and design
2-way system with balanced tuning and uniform sound image
Bass reflex tubes ensure deep, precise bass
Fibreglass mid-range driver with phase plug for excellent speech intelligibility
Large 25 mm tweeter with phase plug and wave guide for a detailed, spatial display
Suitable for all stereo amplifiers or AV receivers, can be placed on stands, a shelf or wall mounted
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.
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.

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 for avoidance of phase shift cancellations resulting in improved transparency and directional behaviour of higher frequencies.
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.
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.
The smaller Ultima also produces a big sound, because it is full to the brim with the latest speaker technology.
Unmatched in every situation
The Ultima 20 is a high-quality bookshelf / rear speaker that makes no compromises. As an individual stereo pair or as part of a home cinema set surround set up, the Ultima 20 comes into its own. The appearance and acoustics fit perfectly with those of its big brother. The speakers can be positioned on a shelf, on speaker stands or wall mounted.
Beautifully finished. Made from sturdy MDF with inner struts. Teufel speakers have a timeless design and long durability.
