Heco Celan XT 501

Heco working with two equally-sized chassis in the low mid frequency range, of which each bottom remains active in the deep bass, while the top is limited by a low-pass filter. Hard to believe, that the normally proportioned in addition to the Dali Heco brings even slightly more weight on the scale as the Colossus from Denmark.

The hexagonal housing contributes a certain amount of this optical weight loss, whose side walls rejuvenate backwards and forwards. This design reduces the risk of standing waves inside the box, which might formed between two parallel walls and return it to the outside through the thin membranes. Heco also achieved a greater volume of housing with narrow front panel. Further upgrades so the horizontal omnidirectional tuned with a tweeter sound leadership.
A positive side effect of the symmetric driver configuration with the 2.5 mm dome tweeter in the Center: the XT 501 acts within the successful Celan series in many AUDIO tests most refined, the chances of allowing you to move the box on the better half passing in the House. Jokes aside: for this class very high-quality finish of Heco’s only good can be reported. Piano lacquer or real wood veneer the choice are as surfaces, the stand plate fixed to the Housing Act the box yet airy.
The bi-wiring Terminal is known from the Celan series, with an additional Terminal for high-frequency connection in addition to the bolted aluminum bass reflex tube is found on the back. It also gives two decibels more thrust of the dome coated with nano-particles the better damping. In the damped AUDIO listening room this variant of while previous Heco tests proved often the more natural.
The surprise was not long in coming: the German tradition brand Heco basically showed a similar vote as the English rival by Mordaunt Short. But only through values-based high-frequency setting with 2 dB more level reached a comparable liveliness as the Englishwoman. The Heco was rather reserved, more Foundation in the bass if also basically with a stick. Voices such as Don Henley or Elvis Costello (“my flame burns blue”, DG) sounded slightly recessed and were sometimes almost with a wafer-thin layer chocolate covered, what Battersea does something striking timbres such as Henley, Costello or Tom Waits (“the asylum years”, Electra) for many perhaps, but also rather deprives them of the rough charm.
In addition, the imaginary stage appeared somewhat lower than with the mezzo 6. But the play had no disturbing edges and corners the Celan, the XT 501 was equally well for any kind of music and drew up a narrow lead over the Mordaunt-Short with their slightly higher color and joy of playing.
