Dali Epicon Vokal Center Speaker

Dali epicon vowel

With the EPICON VOKAL we have developed an uncompromising center speaker for all multi-channel fans. Its chassis assembly with two 165 mm bass-midrange drivers and DALI's hybrid tweeter module corresponds exactly to the EPICON 6, which ensures a reproduction that is just as transparent, rich in detail and tonally exactly matched to the other speaker models in the series.

SMC technology

The new powdered magnetic material (Soft Magnetic Compound = SMC) almost completely eliminates the distortions usually caused by the loudspeaker's magnetic drive.

Hybrid tweeter module

The combination of fabric dome and ribbon, specially tailored to the EPICON series, ensures detailed and very spatial reproduction.

Gold plated connectors

The particularly robust screw connections specially developed by DALI guarantee a reliable loss-free connection to the loudspeaker cable over a long period of time.

With the EPICON VOKAL we have developed an uncompromising center speaker for all multi-channel fans. Its chassis assembly with two 165 mm bass-midrange drivers and DALI's hybrid tweeter module corresponds exactly to the EPICON 6, which ensures a reproduction that is just as transparent, rich in detail and tonally exactly matched to the other speaker models in the series.

The EPICON VOKAL harmonises perfectly with the three main loudspeakers of the EPICON series and stages every film soundtrack and every multi-channel piece of music extremely realistically and with the desired sound pressure. The center speaker can be used in any multi-channel configuration.

50% of the acoustic energy of a normal feature film is reproduced via the center channel. The EPICON VOKAL does this job in an exemplary manner. He renders every word of the actors - whether spoken normally, shouted out loud or whispered softly - so brilliantly and clearly that it is always clear and easy to understand. In addition, noises and tones are staged in a breathtakingly realistic and precise manner.

Linear drive magnet system

One of the technological highlights of the EPICON series is the linear drive magnet system. It is used in all woofers and mid-range drivers and is based on the powdery magnetic material SMC ('Soft Magnetic Compound'). The use of SMC brings many advantages, but above all the distortions in the magnetic drive caused by mechanical losses are reduced considerably. SMC's unique ability to combine high magnetic conductivity with very low electrical conductivity (1/10,000th of iron) enabled the development of an excellent loudspeaker drive without the disadvantages previously accepted. The distortions and thus the discolorations in the sound reproduction could be significantly reduced.

The technical information on the EPICON series, the white paper, explains in detail how the properties of a loudspeaker in terms of hysteresis, current linearity and voice coil inductance can be optimized with SMC. You can download the whitepaper further down on this page in the download area.

Hybrid tweeter

In the interests of the most transparent and realistic reproduction of even the most subtle high-frequency details, the EPICON series is equipped with the unique DALI hybrid tweeter module. This tweeter design was also used in our earlier high-end series - but we developed a completely new dome for the EPICON models. The new module consists of a 29 mm, particularly light dome membrane and a 10 x 55 mm ribbon tweeter. The combination of a dome tweeter with a ribbon tweeter represents the ideal solution for reproducing high frequencies.

Both tweeters are very well protected against any interference coming from inside the cabinet. The dome and the ribbon share a common, extremely stable base plate made of die-cast aluminum and each have their own housing. This ensures that the sensitive tweeters are not exposed to any disruptive resonances.

A particularly low resonant frequency, high resilience and exceptional reserves for high sound pressure and extreme excursions are the properties of our particularly large dome tweeter. With the EPICON VOKAL it starts slowly at 2.75 kHz. The dome then works up to its transmission limit well above 20 kHz without being faded out by the crossover. Thanks to an ultra-thin magnetic fluid for cooling, the dome has a very high saturation limit, which significantly increases its resilience. At the same time - especially at very high sound pressure levels - the voice coil movement is excellently controlled. The dome material itself is very light and so thin that the coating contributes a large part to the structural rigidity of the cone.

The ribbon transmits an extremely wide frequency spectrum and has a superb radiation of very high frequencies. Its range of use begins above 10 kHz, but the ribbon reaches its full potential between 15 kHz and well over 30 kHz, i.e. well above the audible frequency range.

woofer

Two 165 mm woofers ensure a profound bass foundation of the EPICON VOKAL. They work so powerfully that a separate subwoofer is no longer required, even in larger rooms or at higher playback levels. Both chassis feature the DALI-exclusive revolutionary Linear Drive Magnet System.

The latest generation of wood fiber membranes has a new impregnation with a special coating that takes place after assembly. Wood fibers stiffen the cone membranes, which are made of very light cellulose. This structural reinforcement has excellent properties in every respect and also reduces the so-called bursting of the membranes, which causes disruptive partial vibrations.

In order to be able to carry out this process - like the entire production in general - within very narrow tolerances, the introduction of in-house production of loudspeaker chassis was an important step. The woofers of the DALI EPICON series were not only developed in the Danish DALI company headquarters, they are also manufactured there!

Multi-layer housing

Each side panel of the EPICON VOKAL consists of six individual layers of MDF boards glued together. These are firmly anchored to the 53 mm thick, multi-layered MDF rear panel. CNC milling is used to create the ultra-precise recesses and bores for the bass reflex openings and connection panels on the back of the housing.

The 33 mm thick two-layer front wall ensures that the energy mobilized by the drivers is also used acoustically and is not lost in the form of cabinet vibrations. The curved shape of the front wall also contributes to providing the most stable and torsionally rigid acoustic platform possible.

Inside, the housing of the EPICON VOKAL offers two equally sized chambers for the two woofers. The two bass chassis each have an identical but completely independent volume. Thanks to its own sealed housing, the midrange driver is also able to reproduce the particularly critical mid-range frequencies in the range of the human voice without any disruptive influences from the other drivers.

The two associated bass reflex openings can be found on the back of the housing in close proximity to the woofers. The reflex tubes are curved outwards at both ends to avoid disturbing turbulence. The hard-wired crossover is also fixed in its own housing on the bottom of the housing - and is therefore not exposed to the dynamic changes in air pressure within the bass reflex housing chambers.

The division of the housing into several separate, completely separate volumes contributes just as much to the unique sound experience of the EPICON VOKAL as the carefully positioned housing braces or the consideration of the DALI principle of ensuring optimal timing and unhindered air flow in every respect.

The housing surface consists of real wood veneer, which has been varnished a total of ten times. Each individual layer is hand-polished between work steps to achieve a deep, high-gloss and elegant surface. A tenfold coating with a thickness of around 2 mm also ensures a particularly hard-wearing finish. The openings for drivers, reflex openings and connection terminals are cut out after the painting process to ensure a precise assembly.
