Visual and sound revolution of an audiophile legend
The HECO Celan range has been thrilling music lovers and home cinema fans around the world for three generations now. However, rather than rest on their laurels, our design and development team wanted to create a unique, standalone loudspeaker family in the fourth generation as a worthy successor to the legendary Celan GT Series – the Celan Revolution.
Living up to a great name Like its predecessor, the newly developed top speaker range from HECO also answers to the name Celan. However, the new “Revolution” suffix to the name makes it clear that the latest generation represents a fundamental further development of the predecessor models. The goal was to completely reinvent the Celan! Ultimately, this ambitious objective is reflected in the overall acoustic performance as well as the new design concept. The distinctive enclosure with its elegantly angled top and the dominant base brackets of the two floor-standing speakers lends this new flagship range a true individuality and the claim to a new milestone in HECO’s loudspeaker history.
Loudspeaker design away from the mainstream The most important elements on the way to the new Celan Revolution design are the angled top with the embedded metal logo as well as the rounded sides with the housing tapered to the rear. Another key design element of the floor-standing loudspeakers are the sturdy aluminium base brackets, which are more than just a visual eye-catcher. Their solid spikes are height-adjustable, with interchangeable tips ensuring acoustically ideal coupling on all floors. The broad base also guarantees particularly good stability. The new Celan Revolution design is rounded off by elegant surfaces made from selected real wood veneer or high-quality lacquer finishes as well as invisible fastening of the front cover via integrated magnets.
Newly developed chassis for highest audiophile performanceAll of the lou dspeaker chassis were newly developed specially for the Celan Revolution range and optimised to suit the acoustic concept – using, among other things, the Klippel measuring system recognised throughout the industry. The most important new development in the chassis family is the 30 mm high-energy tweeter with the new HECO Fluktus front panel geometry. The special second-generation dome tweeter produces especially well-balanced and harmonious dispersion characteristics at all angles thanks to the computer-optimised multi-wave front panel. In addition, the tweeter is highly resilient with great level stability due to cooling with acoustic ferrofluid and a powerful ferrite double magnet system – taking over music reproduction from a frequency of around 2,800 Hz. Operating below the tweeter in the 3-way models is a pure midrange chassis optimised for full-range reproduction and featuring a particularly lightweight HECO kraft paper membrane that has proven itself over a period of decades. Newly developed phase-optimising dust caps are also used in all models. In the floor-standing loudspeakers, the low and upper bass frequencies are taken care of by Klippel-optimised bass drivers with highly resilient voice coils in a long-excursion as well as linear operating drive system. The midrange drivers have also undergone the same optimisation measures. In addition, substantial wall thicknesses and multiple bracing inside the solid MDF enclosure ensure the best working conditions for the drivers in all models. The result is harmonious interaction combined, at the same time, with very high dynamics and lowest distortion for all imaginable styles of music.
Hi-Fi enjoyment meets home cinema funIt goes without saying that home cinema fans have also been considered in the design of the new Heco Celan Revolution range! In addition to two floor-sanding loudspeakers and a shelf-top speaker which is, of course, ideally suited as a rear speaker, the Celan Revolution range is rounded off by a visually and acoustically matching centre speaker and a powerful active subwoofer.
