A symphony from the past that has arrived in the present with Arcosia
What parameters are required for the development of such a high-quality loudspeaker?
An idea that originated in Christian's first Agile. So it was decided not only to marry the Agile with a top class beryllium tweeter, but to optimize the whole concept. For such a development, the budget had to be increased, that was clear. So the way was clear for a team that could give free rein to its expertise in development, room acoustics and cabinet construction. The team solution of working with Christian on the Agile turns out to be the right one in retrospect, which benefits the performance of this speaker.
The Agile dynamics are way ahead with its innovative Arcosia drivers among the top speaker drivers on the market. Paired with a Beryllium tweeter of the extra class, which has already earned an excellent reputation in various speaker constructions, the basic conditions for a harmonious marriage among top drivers are given.
An excerpt from the Eton product description of the Arcosia chassis
Technique: crossover optimization considering the beryllium tweeter
The main optimization in the high frequency concerns the acoustic and electrical adjustment of the phase. In the acoustic adjustment of the phase, the temporal behavior of the drivers - which is always influenced by a analoge crossover - is optimized so that both the radiation pattern and the transient response of the loudspeaker are very uniform, as with a full-range driver. This means that through the choice of electrical filters and their design it is basically possible to compensate for the depth offset of the different sound origins. This can be seen very well in the waterfall diagram, because here there is no transition between midrange and tweeter (the temporally arranged lines run horizontally through). It is often seen that the tweeters decay earlier and the filter edge of the midrange is well visible in the waterfall diagram as a temporally later event.
Optimizing the electrical phase is about reducing the reactance of the crossover and thus harmonizing the impedance so that amplifiers have optimal conditions to drive the fine, sensitive frequency range as well. With speakers of the acoustic quality of an Agile, it is absolutely essential to optimize all factors and this includes not only the careful choice of crossover components but also the electrical consideration of the complex load (impedance) for the amplifier.
Built-up crossovers: A service for our high quality kits
With high-end crossover components of the extra class like Agile or Satorique, it can become extensive piles of components. If the crossovers also have to be built by the customer, errors can quickly occur. These are difficult to analyze in retrospect, even for the trained ear.
The coils manufactured in Intertechnik's own winding shop enable values that are not available in the standard range in this way. The same applies to our AUDYN capacitors, which have also stood for an excellent price-performance ratio for years.

The eye listens: Kit perfection for your Agile Dynamics
A construction drawing, the building instructions and an email service for the construction project we provide free of charge with the purchase of a kit. If you don't want to build everything yourself, you can enjoy the CNC milled case parts.
We support this and have chosen such a veneer for our Agile Dynamics project.
You can get inspired at: www.designholz.com category SaRaiFo-Fineline-Veneers.
Another option would be to have a finished case built for you. As always, this is all a question of price.
The whole thing is complemented by a screwable crossover compartment, through which one can still very nicely see the continuous inner matrix of the cabinet. The contrast of the Arcosia chassis with the white baffle completes the picture.
Goal achieved: High end with classic virtues again at last
With the amount of loudspeakers that exist today, such an appearance is rather a rare spectacle, because the dinosaurs of the speaker boxes were already threatened with extinction, but only almost . Back to the roots is fully in vogue and so speakers like the Agile Dynamik have reclaimed a firm place among the slim models.
Why then are so few examples to be heard in the high-quality self-build?
It's because the effort is extremely high to build a sound sculpture that meets today's demands in design and sound. If one were to offer the Agile Dynamics as a finished loudspeaker, a purchase sum would come together, which today can correspond to that of a small car. That we find ourselves here in the classic stereo range is probably clear and also requires a high-quality amplifier.
Also high-quality analog crossovers are here a must and not the choice. That also with us the Frostis, as I affectionately call the small DSP Amps, move in, is probably due to the trend of the time, but please not here.
The crossover philosophy has already become a tradition with us. As much as it must be, but also not less. For this reason there is only one crossover for a construct and not three different ones.
Such a loudspeaker should master all disciplines such as tonality, spatial representation as well as coarse and fine dynamics. And so we can look forward to the sound reports of our customers, because everyone has a different perception in their four walls.
What could be repeated by all would be the open mouths of the guests when they hear and marvel that you have built something like this yourselves: a leftover relic from long forgotten times with the sound that modern loudspeaker technology can deliver today.
A sound experience with unmistakable bass that has never lost its character since the 80s until today.
