Celan Revolution Center 4

2-way bass reflex center speaker

The approx. 60 cm wide center speaker of the Celan Revolution series, like the shelf speaker, is constructed as a 2-way bass reflex system and is equipped with two bass-midrange drivers. The two 170 mm chassis, which are optimized for low-distortion reproduction thanks to the lightweight HECO kraft paper cone, feature heavy-duty voice coils and sturdy die-cast aluminum baskets. The newly developed Fluktus tweeter, which features a 30 mm PFC dome and computer-optimized multi-wave front panel, is responsible for perfect dispersion properties in the upper frequency range. Special emphasis has been placed on the acoustic coordination of the vocal range, meaning that when this speaker is used in a home cinema setup, it is capable of reproducing an extremely uncolored sound with a corresponding volume.
