Model 140-15D

This model is caracterized by a ribbon with a length of 140mm and width of 16mm, and also a very high sensitivity. In all models, the first number indicates the effective length of the ribbon, and the second number indicates the width of the ribbon. The housing is made out of 8mm thick steel plates. In the housing there are 4 neodymium magnets, 2 on each side of the ribbon. The custom transformer is also hand wound, manufactured and indestructible. As in other models, the primary is wound with copper round wire of high purity, and the secondary with copper foil that’s 0,1 mm thick. The transformer is partially covered with resin, and the rest of the chamber volume is filled very precisely with absorption material, AZMAFON.

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.

Model 140-15 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.

The ribbon is supplied as 8 ohms as standard, and on special request it is possible to get 4, 12, 16 ohms version or even with 2

or 3 outputs. The model 140-15 is intended for two-way, three- way, four-way systems of very high class and sensitivity.
