The top seller from Berlin
For years, the ULTIMA series has been a byword for excellent price to performance ratio. You won't get this much sound for this little money anywhere else. Featuring superior audio technologies, the ULTIMA series delivers perfectly balanced playback to increase your enjoyment of all genres of music, as well as gaming and of course films. We hear just that all the time from enthusiastic industry journalists and customers. The new ULTIMAs can be easily recognized by the label over the tweeter.
Developed in Berlin
Product development for the ULTIMA series, like all our other speaker series, is completed start to finish here in our Berlin labs and anechoic chambers. After years of cross-team refinement and optimization including a healthy dose of customer feedback, the ULTIMA 40 is a true marvel of engineering.
Tweeter with phase plug and waveguide
Two features that are nearly unheard of at this price point are the tweeter's built in phase plug and waveguide, providing for extreme precision in the high-frequency range.
Mitigates phase interference near the tweeter by directing waves outward toward the listener, enhancing response at high-frequency bandpasses.

Exactingly guides each individual sound, keeping all instruments and voices crisp, clear, and distinct.
All around unbeatable
Whether serving as a standalone bookshelf speaker or rear speaker in a surround set, the ULTIMA 20 does not compromise. It fits on a bookshelf, can be placed on a stand, or mounted on a wall. Both visually and sonically, it's the perfect match for its big sister.
