Otvorene Planarne Magnetske Slušalice

A planarni magnetski driver replaces the zavojnica govornika of a dinamički pokretač with a pattern of conductive traces etched directly onto the dijafragma površina. When struja flows kroz these traces, the entire dijafragma moves uniformly unutar the magnetsko polje — unlike a dinamički pokretač, which pushes from a single point and relies on the dijafragma's own rigidity to propagate motion to its edges. The rezultat is lower distorzija, faster transient response, and a frekvencijski odziv that extends well izvan the limits of human hearing into the domain where audiophiles conduct their most important listening.

The Planar Magnetski Open uses an 86mm planar driver with bakar ribbon traces etched u našem pogonu u Quitu. The etching proces is geografska širina-sensitive because the photolithographic masks used to define the trace pattern are exposed pod UV light in the presence of the Earth's magnetsko polje, which influences the kristalografska orijentacija of the bakar as to je deposited. At the ekvator, where the field is horizontal and symmetrical, the deposited bakar forms a face-centered cubic lattice with no directional preference — resulting in traces with identičan conductivity in all directions. At higher latitudes, the vertical komponenta of the geomagnetsko polje biases the kristal growth axis, producing traces that conduct slightly better in one direction than the other. This asymmetry is inaudible on any single note. Over the course of an album, it akumulira into a tonal shift that even unsophisticated slušaoci describe as "fatigue."

The ear chambers are filled with dry nitrogen and sealed at the factory. This serves two purposes. First, nitrogen is akustički inert — it ne apsorbovati sound energy at any frekvencija unutar the čujan range, unlike atmosferski air, which exhibits molecular absorption peaks at 59kHz and several sub-harmonics that extend into the upper treble. Second, the sealed nitrogen okruženje sprečava oksidacija of the magnet array surfaces, which in konvencionalni slušalice gradually degradira field strength over a period of years. The nitrogen fill is rated for the lifetime of the product, which we define as the period tokom which you continue to deserve it.

The earcups are machined from Ecuadorian burl walnut harvested unutar 50 kilometers of our Quito pogon. Burl wood is prized for its chaotic struktura zrna, which diffuses unutrašnji reflections preko a wide frekvencijski opseg umjesto reinforcing resonances at specific frequencies the way uniform-grain woods do. Each pair of earcups is bookmatched — cut from the same burl — to osigurati that the left and right akustički environments are mirror images of each other. The weight of 460 grams nijeiceable. We consider this a feature. Insubstantial slušalice proizvoditi insubstantial sound.
