HECO Celan Revolution 9 – State-of-the-art floorstanding loudspeaker with dual bass drivers

The HECO Celan Revolution 9 is the largest floorstanding speaker in the Celan Revolution series, combining modern design with powerful, wide-ranging, and highly detailed sound reproduction. As a fully-fledged 3-way bass-reflex speaker, it features a powerful dual bass configuration with two 200 mm woofers and a 170 mm midrange driver. The proven HECO kraft paper cones ensure natural sound reproduction, high power handling, and a confident, deep bass response.

For precise high-frequency reproduction, the newly developed second-generation Fluktus tweeter with a 30 mm PFC dome and computer-optimized multi-wave front plate is used. The special Fluktus geometry improves the dispersion characteristics and enables balanced reproduction with natural timbres. The midrange driver has been specifically tuned for neutral reproduction and features a HECO kraft paper cone and a POC dust cap for phase optimization.

The Celan Revolution 9 also boasts high-quality construction. The multi-braced MDF cabinet features rounded sides and an elegantly angled top. Solid aluminum crossbars with height-adjustable metal cone spikes ensure stability and optimal decoupling from the floor. Depending on the surface, interchangeable metal or rubber spike tips can be used. The front cover, made of acoustic fabric, is invisibly attached magnetically and can be removed if needed.

The high-quality connection terminal with gold-plated, encapsulated screw terminals allows for bi-wiring and bi-amping. The tweeter level adjustment allows the reproduction to be set between "linear" and "+2 dB". A sophisticated crossover network with high-quality, tightly toleranced components completes the technical features.

With an efficiency of 93 dB, a power handling capacity of up to 450 watts, and an exceptionally wide frequency range of 19 Hz to 52 kHz, the HECO Celan Revolution 9 offers ample power reserves and versatile amplifier compatibility. This makes it a compelling choice for demanding stereo systems where powerful bass, high dynamics, and finely resolved details are equally important.
