Features
All technologies at a glance
Engineered in Berlin
Our laboratories and anechoic chambers are still where we engineered the current ULTIMA Mk4 Series. We gave the design a facelift and made it look a little nicer – it is now more timeless and modern than ever. We also incorporated tons of customer feedback.
Value you can feel
The front, which now features a very purist design, has also hidden the cover mounts better. The covers themselves look more elegant and feel similar to a high-quality textile, which makes them easier to fit into any living room.
