Heco Floorstanding Speakers Celan Revolution 9 Piano Black

3-way bass reflex floorstanding loudspeaker with double bass
Large state-of-the-art floorstanding loudspeaker with outstanding acoustic properties. The eye-catching features of the largest floorstanding loudspeaker in the series are the angled top and the solid aluminum crossbars, which provide a broad base for a firm stand. Height-adjustable metal spikes are used for perfect decoupling from the floor and thus clear the way to unadulterated high-end listening pleasure. In the bass and midrange, two 200mm woofers and a 170mm midrange driver with the tried and tested HECO kraft paper cone, which is known for its audiophile sound characteristics and high level stability, are impressive. The newly developed Fluktus tweeter with computer-optimized multi-wave front panel and 30mm PFC dome plays its entire frequency spectrum without exaggerating and with very natural timbres.
