HECO Celan Revolution 9 Floor-standing Speaker

Large state-of-the-art floorstanding speaker with outstanding acoustic properties. Eye-catching features of the largest floorstanding speaker in the series include its angled top and solid aluminum struts, which provide a broad base for a secure footing. Height-adjustable metal spikes ensure the speaker is positioned at a perfect distance from the ground, thereby paving the way for an unadulterated high-end listening experience. The bass and mid-range frequencies are catered for by two 200 mm woofers and a 170 mm midrange driver with tried and tested HECO kraft paper cones, which are renowned for their audiophile sound characteristics and high level stability. The newly developed Fluktus tweeter, which features a computer-optimized multi-wave front panel and 30 mm PFC dome, reproduces its entire frequency spectrum with very natural tones and without any form of exaggeration.
