Just in time for the 60th company anniversary head thinker Shandro access Fischer and developer Martin Groß solutions from the early years.

Was it but then quite common to accommodate cone chassis not in sealed enclosures, but in open back designs. This construction is used for the first time in a modern speaker what the developers promise a particularly clear and completely free of resonance Center playback. By the way can the rearm radiated noise components, because they swing opposition to the front, the dispersion Linearize. The construction of the Central chassis itself can also sit up retro HiFi fans: the membrane consists of a cardboard wool blend, called kraft paper, and passes into a coated, multiple folded fabric surround. So, while most manufacturers on space-saving neo dynamic or bulky ferrite magnetic material, Heco installed so-called AlNiCo drives, an alloy of iron, copper, aluminum, nickel and cobalt. This traditional material has the advantage that it virtually always the same behaves under all temperature conditions, which should benefit freedom of compression and dynamics.
Back to the roots
When the woofer, the usage of AlNiCo is not economical, because the material is sensitive on opposing magnetic field, they can almost always occur when a low-frequency coil flows through strong currents. With a mixed construction of paper Cone and carbon dust cap, are the two 20 cm bass is conventionally built, promise for this enormous displacement and a deep lower limiting frequency. The duo plays namely to under 40 Hertz down, before the draft to almost unbelievable 27 Hertz draws a trio of rear-mounted bass reflex tubes. Moderate listening room and taste to fit in the box, the Tri-wiring terminal with special cable bridge provides two alternative inputs: once to moderate raising of the heights, to the lowering of the centers. The statement case shows off almost wasteful processing quality: piano lacquer, aluminum Bezels and reflex tubes, hexagonal shape. This box appears already to justify their price before she played a sound.
Its masculine shape like pandering to the Association, the box overdoing it on bass and volume, rashly to impress contemporaries. Nothing there: the Heco sounded even more balanced than the somewhat dark timbered KEF XQ_40 (AUDIO 3/08), celebrated “baby talk” (“Great music Vol. 4 “) with charm, vocal power and lots of rhythm, where the KEF minimally to slow acted and got something out of step. The final Waltz beats sounded so wonderfully open and with a crackling atmosphere the piano passages of Strauss ‘”Rosenkavalier Suite” (GUSCHLBAUER, EMI), so adorably spirited. After this passage, it was clear that the Heco the best shoots high. There it took as an unbeatable instance of Geithain ME__150 (AUDIO 9/07), it again one to brake. But first the Heco threw their dynamic talent to bear and he showed whether the subsonic undertones in “Baby talk” slightly uncertain ME_150 what good is so much surface. She was clearly at a disadvantage, however, on the subject of illustration. Dietrich Fischer-Dieskau sonor and creamy to his “winter journey” at (Moore, DG), was a handsome singer but not so clearly defined onstage rather a case shadow because. But such blunders with conciliatory tones and a downright incredible feat forget the Heco: with their incredible ability to breathe analog warmth and subtle clarity even harshly produced CDs such as progressive “Fugazi” (EMI) – as this was not a synthesizer-based, flat digital production from the 80s, but an acoustic LP from the good old times.
