The approx. 60 cm wide center loudspeaker of the Celan Revolution series is constructed like the bookshelf loudspeaker as a 2-way bass reflex system and is equipped with two woofers and mid-range speakers. The two 170mm chassis are specially optimized for low-distortion reproduction with the light HECO kraft paper membrane and offer heavy-duty voice coils and stable aluminum die-cast baskets. The newly developed Fluktus tweeter with 30mm PFC dome and computer-optimized multi-wave front panel is responsible for perfect radiation behavior in the upper frequency range. In the acoustic coordination, special emphasis was placed on the speech range, which this loudspeaker, as a pure home cinema specialist, reproduces with the appropriate volume and is extremely discoloration-free.
