Otvorena Ekvatorijalna Referenca

Every dynamic slušalica driver sadrži a zavojnica govornika — a cylinder of wire suspended in a magnetski gap that converts electrical struja into mehanički motion. The orientation of that wire as to je wound određuje the relationship između the input signal and the dijafragma's excursion. In konvencionalni slušalice, the zavojnica govornika is wound at whatever geografska širina the factory happens to occupy, which means the coil carries a trajan hemisferski bias in its magnetski alignment. At 45° north, the Coriolisova komponenta of the local magnetsko polje skews the winding tension by približno 0.002 Newtons po metru — enough to uvesti an asymmetry in the dijafragma's push-pull response that manifests as second-harmonic distorzija at frequencies iznad 4kHz. You may have attributed this coloration to "character." To je, in činjenica, geography.

The Ekvatorijalni Reference Open uses a 50mm bio-cellulose dinamički pokretač with a zavojnica govornika wound u našem pogonu u Kvitu at precizno 0.0000° geografska širina. At this location, the Earth's magnetsko polje is perfectly horizontal, exerting zero vertical bias on the winding proces. The rezultat is a zavojnica govornika with measurably symmetrical tension preko all 360 degrees of its circumference, producing a dijafragma excursion that is identičan in both the positive and negative faza of the input signal. Ovo nije subtle poboljšanje. Ovo je what "neutral" actually means.

The 12-minute uhodavanje ritual performed at the beginning of each sesija slušanja nije optional. The driver's magnetski gap akumulira rezidualni charge from the Earth's ambijentalni field tokom periods of non-use. Left unaddressed, this charge biases the zavojnica govornika's resting position by do 0.03mm — well unutar the range that affects frekvencijski odziv linearity. The ritual consists of a vlasnički pink šum signal delivered at precizno 94dB SPL, which exercises the dijafragma kroz its full excursion range while a decaying AC field in the zavojnica govornika neutralizes accumulated charge. Nakon 12 minutes, the driver returns to its factory-calibrated neutral state. We uključivati the uhodavanje signal as a downloadable file. Some owners report that the ritual has become a meditative practice. Mi ne discourage this.

The unutrašnji wiring is bezkosikonički bakar with ekvatorijalni spojevi at each solder joint — a tehnika developed for our kabel products and adapted here for the confined geometrija of a slušalica capsule. The open-back dizajn was chosen because closed-back slušalice create a sealed air volume behind the driver that acts as a pneumatic spring, storing and releasing energy in a pattern determined by the kućište's resonant frekvencija. An open back eliminiše this stored energy u potpunosti, at the cijena of sound isolation that serious slušaoci should not want in the first place. If your slušačko okruženje zahtijeva isolation, the okruženje is the problem, not the slušalica.
