Model 70-10

This model is a bit bigger than the 64-10 one. The housing is formed out of laser-cut steel plates with a thickness od 10mm. The housing forms a chamber in which the adaptive transformer is placed, which is being wound by hand.

The primary of the transformer is wound with a high-purity copper wire, and the secondary with a copper foil with a thickness of 0,10 mm. The transformer is indestructible, and the housing is filled with resin to eliminate vibrations. Standard core of the transformer is amorphous, and it can also be ordered as nanocrystalline. The rest of the space in the chamber is filled with absorbent material, in this model it is AZMAFON.

At the top of the housing there are two very strong neodymium magnets which are located on both sides of the longer edges of the ribbon. The faces of the magnets are shaped in a way to direct the magnetic field towards the center in the zone where the ribbon is located.

The ribbon itself is made out of 8 microns thick aluminum foil, which is ironed and stiffened by a particularly critical process. This ribbon doesn’t have carrier foil made out of MYLAR, it’s in direct touch with air. This provides the smallest possible moving mass, several hundreds of times smaller than any classic DOME tweeter and far smaller than RIBBONS with a MYLAR carrier foil.

The result is shockingly rich, detailed, the sound image is unencumbered by any colorations.

The ribbon itself is fixated on the ends to the supporting frame via tensioners. After installation, the ribbon is being precisely tensioned in order to achieve optimal performance. This model has a ribbon that’s 6mm longer than the ribbon of the 64-10 model. In all models, the first number indicates the effective length of the ribbon, and the second number indicates the width of the ribbon.

Model 70-10 is user serviceable, which means that the user can replace the ribbon himself if necessary.

The FACE PLATE is laser-cut, hand processed, and the final processing is powder coating.

Model 70-10 can be used in small two-system book shelf speaker boxes in micro monitors, central speakers, as well as in larger sub-state three or four way systems.

Like every other model, this one is characterized by exceptional openness, detail, spaciousness and depth of the sound image. The sound is fluffy, colorless, it will not hide or mask even the finest information read from the source.

The speaker is supplied as 8 ohms as standard, and on special request it is possible to get 2, 4, 16 ohms version.
