With the airplain active loudspeakers, the name says it all. Phli, Pronounced like the word fly, it means phase-linear. All airplain products have this characteristic and this is what makes the sound so incredibly authentic.
The main system includes a Roon®-compatible DSP streaming box developed by Weiss Eingineering. It allows various adjustments to the room.
Both the main systems and the subwoofers are driven by integrated “Eigenakt” power amplifiers from Purifi.

phli U-Series
The phli U-series is like the phli series phase linear in decisive transmission range.
With theses series, a pure active speaker series was created, without an external streamer/DSP unit. With the U-series, any streamer with digital or analog output can be connected. A DANTE™ network connection is available on request, making it possible to place the source further away from the speaker or to integrate it into a home theater solution.
