Celan Revolution 3

2-way bass reflex shelf speaker

Compact high-end shelf speaker with an audiophile configuration and a distinctive visual appearance. The most striking design elements include the angled top with the embedded metal HECO logo, as well as the rounded side panels and rear tapered housing. All of the frequencies above approx. 2,800 Hz are catered for by the newly developed Fluktus tweeter with its 30 mm PFC dome. The computer-optimized multi-wave front panel ensures a harmonious dispersion over the tweeter´s entire frequency range. The 170 mm bass-midrange driver utilizes the particularly lightweight and reliable HECO kraft paper cone, which is characterized by its outstanding audiophile sound characteristics and high level stability.
