ARCONA –

THE FIRST STEP INTO OUR WORLD OF HIGHEND SPEAKERS

The Arcona series is the perfect entrance into our world of HighEnd loudspeakers! Equipped with all the technologies of our most elaborate loudspeakers the Arconas show what is possible in their price ranges. They are ideal for people who love music and want to break up to new horizons in sound reproductions. From the small bookshelf Arcona 40, a high-pass filtered closed-box 2-way design to the big Arcona 100, an elaborate double-woofer 3-way system with a very elegant shape the technical solutions lead to a natural dynamic sound which is outstanding in its price classes.

Like all our loudspeakers also the Arconas show all the technologies we are known for: stiff cabinets, symmetric ultra steep frequency crossovers, light but stiff diaphragms and our new Accuton ceramic tweeter. The Arconas show the difference between normal music reproduction and a spatial image that leads to a perfect illusion of the music event. Even studio recordings get a new fascination.

THE FIRST STEP INTO OUR WORLD OF HIGHEND SPEAKERS

SYMMETRICAL ULTRASTRIC PARTICULAR FREQUENCY SWITCHES WITH ALMOST 50 dB SLOPE

Unique worldwide: symmetrical crossovers with ultrasteep slopes

The human ear can detect 10 octaves reaching from 16 Hz to 16.000 Hz. As there are totally different requirements for bass and highs response it makes total sense to divide the audible spectrum into several parts and use several specialized drive-units to reproduce the whole audible spectrum. To coordinate the interaction between the different drivers a frequency crossover is needed which allocates each frequency range to its corresponding drive-unit. The problem is that the separation between the single frequency ranges is not infinitely steep but very flat! This results in a big frequency overlap of the single units.

As all standard crossovers work with a slope of 6 dB/octave only it appears that there is an overlap region where the different drive-units radiate simultaneously even though they are totally different in size and on different geometrical places at the speaker baffle. It is quite obvious that this overlap leads to distortions in amplitude and phase and thus changes the impulse and frequency response of the whole loudspeaker to the worse!

Within the last years we have developed a new analogue crossover technology which is able to create a phase-linear filter with a slope of more than 50 dB/octave. This is very, very close to the theoretical ideal of an infinite slope! So the woofer radiates bass, the midrange driver mids and the tweeter only highs. Minimum overlap appears! Impulses stay impulses!

Moreover, our crossovers are built up symmetrically so that the electrical interaction between the loudspeaker's electro-magnetic feedback to the driving amplifier is significantly reduced. This leads to an amazingly clean and transparent sound

PATENTED X-PULSE MEMBRANE

Kicking Bass and Smooth Mids - The XPulse Diaphragm

Only hard diaphragms can exactly follow the electrical impulses of an amplifier to generate an acoustical wave-front which produces music in our heads. On the other hand no each hard material is suited as many hard material have bad resonances and sound cancellations within the midrange passband. Therefore many properties of materials have to be considered to get the perfect loudspeaker diaphragm.

Thus we constructed our XPulse diaphragm: hard enough to reproduce mids with high resolution but damped enough to give the smooth, natural sound which pleases our ears. Hard aluminium shaped to a stiff cone with a damping polymer on its back - that's the composition which gives perfect behavior. By the perfect shape of the aluminium diaphragm we do not need a dust cap for stiffening for our 7"-drive-units. Another reason for the excellent performance!

And so our Arcona drive-units belong to the most sophisticated loudspeakers in the world. So, please, listen to these loudspeakers and reach a new level of music reproduction in HighEnd Audio!

HIGH RESOLUTION ACCUTON CERAMIC TWEETER

The new class of tweeters - the new Accuton ceramic tweeter

Imagine the following: a tweeter in a loudspeaker cabinet must radiate frequencies of at least 20 000 Hz, i.e. the diaphragm must oscillate 20 000 times per second forwards and backwards. Only diaphragms made of a very light material can do this, but it must still be very stiff and hard to prevent it from bending.
For many years, the German specialist Accuton has been producing unique ceramic diaphragms that combine precisely these obviously contradictory properties.
After a development period of 2 years, we have now succeeded in developing a ceramic tweeter together with Accuton, which now brings all these properties to the Arcona series. Already after the first seconds of listening you will realize that we are breaking new ground in this price range. Never before has there been such an enormous resolution, such a wealth of detail.
The perfect entry into the absolute HighEnd!

WBT-NEXTGEN-TERMINAL

WBT-Nextgen-Binding Posts - the Best of the World Market's Leader

Binding posts connect the cables from the amplifier to the loudspeaker. This is not trivial. In fact it is one of the most important connections of the whole system. High currents are driven by the amp to the speaker to supply the energy and the feedback from the loudspeaker to the amp must not have any reduction as the amp has to control the speaker's behavior.

So these binding posts have big influence on the sound of the whole system. We therefore made a lot of listening tests with different binding posts from different suppliers. And one product finally made it: the new WBT Nextgen connectors! It was clearly audible that they had the least influence on sound and dynamics. Another fact that shows you how carefully our Arcona line was designed and developed.

ACOUSTICALLY AFFECTIVE DROP-SHAPED HOUSING

Sophisticatedly manufactured, Free of Resonances - A New Class of Loudspeaker Cabinet Design

It is a well-known fact that all loudspeaker cabinets have big influences on the total loudspeaker behavior and reproduction prroperties. Cheap cabinets kill the sound, cheap cabinets look ugly, cheap cabinets are cheap and useless for music!

In many extended research procedures we could show that the drop-shaped cabinet is best for audio reproduction. It has least reflections and no diffraction effects from edges and corners. So no unwanted sound cancellations occur like known from all other cabinet shapes.

ACCESSORIES

The accessories include adjustable spikes with the corresponding metal bases, a spirit level for adjustment, a black cover frame with self-adhesive, removable Velcro points and a pair of gloves, polishing paste in a jar, a special polishing cloth (only for piano lacquer versions).

Individually adjustable spike feet are also available, which help the Arcona floorstanding loudspeakers to stand even more securely. For the ARCONA 40 we offer an optional speaker stand.
