The Danish loudspeaker industry (DALI) has evolved from the stamp of a retail chain to one of Europe’s most ambitious boxes manufacturers. Base is a bustling Development Department developed now even completely new magnetic materials. An acoustical fluke, as demonstrated in the test of the DALI EPICON 2
On the last high end asked Lars Worre, Managing Director and technological mastermind at the Danish Loudspeaker specialists DALI, to a very exclusive press conference – and held a one-hour lecture on the topic “Constrainers classic magnetic drives” without further ADO.
The sympathetic Dane of course not without deeper meaning made the challenging excursion in the theory. The DALI Development Department had done much research and had it on a new magnetic material , which produced allegedly much less distortion than conventional magnets. Worres lecture was pretty smoking me head, but he was equally interesting as promising, and I could immediately spot of the virtues of the new material using the status box convince EPICON 6. That sounded fantastic.
Six months later the Danes have operated a little fine tuning and in the series brought finally the smallest model in the market: the EPICON 2.
The EPICON 2 is conceived as a classical Two-way construction in a bass reflex cabinet. The 7-inch bass-midrange speaker with the reddish-colored cardboard Cone and the long wood fibres looks familiar, is completely newly developed but only because the new magnets. The distortion due to the new drive be lower especially in the midrange area, which is why low-midrange driver especially benefit. In the treble, the Danes now likes to put on tweeter and Ribbon combination.
But the best 28 mm fabric dome must come without support. Can it go well? Don’t worry: Even if the larger EPICON 6 or 8 EPICON creates the additional Ribbon tweeter more than five percent of the treble energy. When comparing EPICON 6 and EPICON 2 nothing was missing me anyway…
The housing produced in Denmark has been optimized in long trials. It is stiffened rounded like a ship’s hull, at its critical points and consists of six thin, with laminated MDF panels on the sides.
The front, the cover, and especially the back are once more: the baffle comes to 33 mm, back even to 53 millimeters. This gives enough opportunities to make sumptuous cuts the DALI joiners. The slightly rising lid is also massively run and rise slightly to the rear.
Even when DALI knowledge of the important role of the headboard to the acoustic know-how. The energy radiated across the lid can evil affect the figure – why one is well advised to attenuating these part of the box. MAGNAT about doing extremely consistent. The unfortunately already deceased American speaker Developer Jim Thiel could lecture evenings in the lid into the overall concept is as important.
Such additional measures were not necessary at the bottom the EPICON 2: it consists of a stable Chamber, which forecloses the (hand-wired) crossover against the noise and pressure waves of the music.
An insight from the long rows of research to the EPICON was: the impedance of the speaker must not too vary, because otherwise the amplifier works not perfectly. The latest stereoplay researches point Yes exactly in this direction. The voice coil impedance of EPICON music is about aluminium rings linearized, therefore suggesting the phase response.
Also revealed the EPICON 2 what to get from speakers of this size: a maximum level of 97 decibels and a lower limiting frequency of 43 Hertz – not exceptional, but not bad either. Excellent, however, are the distortion values above 1000 Hertz. Perhaps the new SMC magnate material shows its advantages here.
The new magnetic material
The Classic drive a loudspeaker chassis are commonly looks: a voice coil (usually made of copper), who bonded directly to the membrane sits floating freely In the air gap of a permanent magnet. The music signal is given to the voice coil, which in turn is brought by the electromagnetic interaction with the magnet up and low vibration.
So far so good. However, that has all side effects. Conventional magnets made of iron is electrically charged and produce such distortions. Dalí magnetic compound is soft material (SMC) is 10,000 times less electrically conductive with equal magnetic strength and thus much distortion poorer.
The establishment of
The EPICON 2 belongs to the so-called Bookshelf loudspeakers, but has nothing on the shelf between books, but nothing lost. The Danes leave out gently run the small 7-incher soon down, and for this he goes very deep.
In the stereoplay listening room was his appearance at normal levels of large standing speakers cannot be distinguished. That also means: this speaker will and should be free-standing. The corresponding stand (price: 350 Euro) fits visually as well as sonically very well. And with our space computing service position for optimum bass reproduction is usually quickly found.
The tonal experience
The sound was really great. Because I knew the benefits of the new magnetic material, I tried to make this larger distortion in the drive somehow catching. Without success, because the small DALI enchanted me and the other present members completely with her getting hold of three dimensional, completely detached from the speakers sound. Man closed his eyes, sat the Auryn Quartet from the title CD almost before the listening couch: two violins, Viola and cello, fanned out in a semicircle, captured by tacet-chef Andreas Spreer very directly and alive. It sounded exactly like how these instruments in natura sound.
“What go on otherwise. With these shots all boxes sound good”, Mr Breddin crabs. He is right. So it had the rich bass layers of Yello.
What thus conjured up the small EPICON deep bass Foundation and dynamics, was simply surprising. Not according to a compact monitor, but – at a surprisingly high volume – that sounded like adult status box.
Commonly small bass sound when the level rises due to distortion of also soaring quickly “small”. Not so the EPICON 2, which here similar to sovereign acted as stereoplays duration reference B & W 805 diamond.
Both fought a thrilling duel for supremacy in this class, where even one, even the other was. The B & W was the height a bit finer – the diamond tweeter is hardly to beat – and gave a total somewhat Mercurial. DALI played there against something earthy and in the middle of the substanzieller – perhaps a bit “nicer”.
Bottom line resulted in a stalemate, which exhibits an excellent witness to the EPICON 2 and makes them one of the best compact monitors in our days.
