1st Technology: A new name, a new series? There is a little story about this
Since the little newcomers sound fantastic to us after the break-in, we immediately chose the appropriate name for them - and decided to launch a new series under this name. With the first work of this series, however, we have also set a new standard for further developments.
"Flamenco" it has become, because this music is characterized by the expressive playing of the guitars. This lively and room-filling sound experience, as a flamenco player can elicit from his guitar, sums up what this development is capable of playing. And so, unplanned but not haphazard, a new series was born, which we would now like to present to you.
The advantage of ribbon tweeters is their elongated shape, which allows for optimal sound dispersion for vertical placement of speakers in rooms. If you start from the shape of tweeters only, you will notice that especially small tweeters play very cleanly and brilliantly. However, small diaphragms are not particularly level resistant. The ribbon principle, if it is properly constructed and also has an appropriate diaphragm stroke, is simply an ingenious solution.
The typical, clean ribbon sound with its brilliant high frequency range is not only based on the low diaphragm mass and the precise sound generation, but especially on the low concentration in the super high frequency range due to the small diaphragm width. This sound generation is described as very precise and clear to bright and brilliant. A side effect of the elongated diaphragm is that the edge diffraction at the horizontal edge, i.e. the upper edge of the speaker, but also of the beads of the cone drivers located below and/or above, is significantly damped. This enhances the effect of a brilliant high frequency range and a clean reproduction of consonants, hi-hats and other high/bright tones. This is a characteristic that is also necessary for the perfect tonal reproduction of guitar sounds, as their harmonics convey the liveliness and dynamics of a guitar - well, a concert or acoustic guitar.
The frequently encountered disadvantage of ribbon tweeters is distortion (THD). In the case of this ribbon tweeter, they are pleasantly low above 3,000 Hz, so that the Fountek Neo ribbon tweeter can show its best side at a correspondingly high crossover frequency and is capable of real flights of fancy.
Another challenge that a loudspeaker designer has to master is the rear damping of the ribbon. This task is comparable to all closed tweeter design principles, since the sound emitted to the rear must be damped very thoughtfully. Sound from the rear can lead to a very wavy frequency response in the case of reflections or resonance behavior, which virtually chops up the high frequency reproduction - and that's not exactly nice to listen to. The damping of the Fountek Neo has been solved excellently, and this outstanding tweeter is completely convincing in this discipline as well.
The sound opening between the drivers, shaped as a waveguide, and the particularly narrow ribbon are an excellent basis for the production of the very finest tones, so that it is optimally suited for our project in all points. The Fountek Neo ribbon has been equipped with additional mechanical protection in the form of a fine mesh, which is placed in front of the diaphragm in addition to the grille.
The reference drivers have a black through-dyed membrane, whose paper is reinforced with Kevlar fibers. The new diaphragm is not only black as night, it has also been further optimized with a new coating. If you take a closer look at the RS150 chassis used here, it is noticeable that the drive of the new version has received a larger magnet and also that the centering spider has been revised. These are both measures that explain why the revised bass-midrange driver can play even more precisely and balanced. On the one hand, the optimization of the centering spider counteracts bead resonance effects and also significantly influences the playing style in the midrange, on the other hand, a stronger magnetic field always leads to a more precise playing style, the strongest possible drive is virtually indispensable for precise reproduction. For the coil carrier material, aluminum is used in the bass-midrange drivers. Because of its electrical conductivity, this is always a controversial topic among scholars, but in terms of heat dissipation and rigidity, it remains a quality feature for the very best music reproduction.
So and now we are at the control center of the box: the crossover network
A really nice fine detail and naturalness of the reproduction is also an outstanding quality of the Flamenco 1. In order to achieve this objective optimally with a few good components, we have again carefully selected the appropriate components from the versatile Intertechnik range and by an unconventional filter circuit with a parallel connection of coils in the low-mid range built a crossover that supports the midrange, so that this plays more balanced. More balanced means without relevant emphasis in any frequency range.
The coupling of the ribbon is quasi "English", to choose this also old term. It refers to a rather pronounced dip in the presence range, which leads to a good acoustic stage. The crossover frequency is set according to these old crossover concepts, so ideal for the drivers we use.
2. cabinet construction: no finish worries with beech fineline panels

When working with MDF, problems with transitions always arise.
"Butt to butt" with MDF panels brings with it the problem of painted edges reappearing on the surfaces over time. Unless you own a table saw or plunge saw with a guide rail, but who has that as a beginner. However, you can take advantage of the edges by choosing the beech Fineline panels chosen here ( now available in all standard hardware stores ) and buy the optics at the same time.
If you have the appropriate tools available, you can give the speaker its individual touch, but to get a taste of loudspeaker construction, this is not absolutely necessary. This solution should be a suggestion for a simple, but beautiful finish.
Whether the baffle is glued directly or later depends on the finish chosen. If only the baffle is painted, care must be taken that no paint gets on the beech panels. That's why I chose the second option.
To achieve more stability when fixing the glued cabinet, I put the baffle not glued on top and tighten it with two tension belts. The tension belts are available in every hardware store for a few euros.
After the joint glue dries, comes the sanding of the cabinet. Since the beech is harder than ordinary MDF, it should be done with a random orbital sander or an equivalent alternative. With MDF, a sanding block is also perfectly sufficient.
A cordless screwdriver with a hole saw is also not sufficient for the opening of the bass reflex tube. Drill and jigsaw or the router must be used. Don't forget the holes for the binding posts.
Next, the crossover can be placed in the speaker cabinet and fixed in place. The woofer is soldered on and for the tweeter the cables are screwed. For the damping we take half a mat of Sonofil. There we tear a hole in the middle and pull it over the bass reflex tube. Insert all drivers, screw them together and the Flamenco 1 is ready. Not so hard, is it?
3rd sound: The Flamenco enchants already by its fresh liveliness in the whole room
The Flamenco rarely gets out of time, its timing is lively and at the same time finely dynamic.
If at all, only the ribbon tweeter would be responsible for this. However, especially during music broadcasts from a live concert, it shows that its airy, relaxed way of presenting music is one of its strengths. The Flamenco enchants with its fresh liveliness throughout the room.
Take a piece of music that you have experienced live and let the direct manner of the Flamenco cast a spell over you once again. Quite with a slightly silvery tone, that's intentional, otherwise we'll end up with a dome tweeter again. The choice in loudspeaker design makes it exciting. The sound body of an acoustic guitar is presented above the wonderfully natural and voluminous playing midrange driver. This is quite remarkable for its size.
I would advise against angling the speakers. The stage seems a bit disjointed
and one or the other musician starts to play for himself instead of together with the band. If you let the Flamenco play frontally on you, the stage fits perfectly.
