    Precision Engineering: Tweeter with Phase Plug and Waveguide

    Setting a new standard in its price range, our speakers boast cutting-edge features including a built-in phase plug and waveguide, ensuring unparalleled precision in the high-frequency range.

    Phase plug

    Designed to minimize phase interference near the tweeter, directing waves outward toward the listener for enhanced response in high-frequency bandpasses.

    Exacting in its function, the waveguide meticulously guides each sound, preserving clarity and distinctness of every instrument and voice for an immersive listening experience.

    Advanced Performance: Kevlar Mid-Range Driver with Phase Plug

    Our meticulously crafted mid-range driver combines a generous size with a phase plug, ensuring not only clear and intelligible speech but also a rich, natural mid-range tone. Experience optimal sound dispersion across a wider area, delivering unparalleled warmth and clarity throughout your listening space.

    AV receiver required

    This surround set requires an AV receiver to be used. It amplifies and distributes audio and visual signals. If you do not already have a compatible AV receiver, you can find many options under our accessories category or complete sets in our home cinema category that come prepackaged with a receiver.

    High-end tech

    The smaller Ultima also produces big sound, because it is packed to the brim with the latest in audio technology.

    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.

      "...the price/performance ratio will blow you away"
      Der Vinylist

      „ The whole frequency band is very balanced, there are no unwanted behaviors, although we would have accepted some. [...] It also seems worth mentioning to us that we feel very well taken care of with the ULTIMA 20 even with songs that have a lot of dynamic range" "Overall, the ULTIMA 20 represents a very good start and the price/performance ratio will blow you away. The sound is equally transparent, brilliant, lively, clean and forward without losing its balance. Of course, larger and more expensive devices can do more, but for rooms up to 20 square meters, this speaker is a good choice. And you can always upgrade the stereo system to a surround system with more speakers."
