The HECO Celan series has now thrilled music lovers and home cinema fans all over the world for three generations. However, our design and development team did not want to rest on their laurels, but wanted to create a unique and independent speaker family in the fourth generation. A worthy successor to the legendary Celan GT series is the Celan Revolution.

A big name obliges

The newly developed top-of-the-range speaker series from HECO goes by the name Celan, just like its predecessors. However, the suffix “Revolution” makes it clear that the latest generation is a fundamental further development of the previous models. The goal was to completely reinvent the Celan!

Ultimately, this ambitious goal is reflected in the entire acoustic performance and the new design concept. The striking housing with its elegantly angled top and the dominant base beams of the two floorstanding loudspeakers gives this new flagship series real individuality and the claim to a new milestone in the HECO loudspeaker history.

Speaker design outside the mainstream

The most important elements on the way to the new Celan Revolution design are the angled top with an embedded metal logo and the rounded side panels with a casing shape that tapers towards the back. Another defining design element of the floorstanding speakers are the stable aluminum base trusses, which are not just a visual eye-catcher.

Their massive spikes are height-adjustable, interchangeable tips ensure acoustically ideal coupling on all floors. The wide base also ensures a particularly secure stand. Elegant surfaces made of selected real wood veneer or high-quality paint finishes as well as an invisible fastening of the front cover using integrated magnets round off the new Celan Revolution design.

Newly developed chassis for the highest audiophile performance

All loudspeaker chassis have been newly developed specifically for the Celan Revolution series and optimized for the acoustic concept. Among other things, with the industry-recognized Klippel measuring system. The most important new development within the chassis family is the 30 mm high-energy tweeter with the new HECO Fluktus front panel geometry.

The special 2nd generation tweeter dome delivers particularly balanced and harmonious radiation characteristics at all angles thanks to the computer-optimized multi-wave front panel. In addition, the tweeter is highly resilient and level-stable thanks to cooling with acoustic ferrofluid and a powerful ferrite double magnet system. It takes over music reproduction from a frequency of around 2,800 Hz.

Treble in a class of its own

Below the tweeter, the 3-way models have a pure midrange chassis optimized for broadband reproduction with a particularly lightweight HECO kraft paper membrane that has proven itself over decades. Newly developed phase-optimizing dust protection caps are also used in all models.

The bass and upper bass in the floorstanding loudspeakers are handled by Klippel-optimized bass drivers with heavy-duty voice coils in a drive system that is both long-throw and linear. The bass-midrange speakers in the series also underwent the same optimization.

In addition, high wall thicknesses and numerous struts inside the solid MDF housing in all models ensure the best working conditions for the drivers. The result is a harmonious interaction with very high dynamics and minimal distortion for all conceivable music styles.
