Zero-Ohm-Coil

Our Zero-Ohm-Coil (ZOC) not only is a remarkable milestone in our +25 years lasting company history but certainly a true milestone within the field of audiophile coil technology in general. too. As back then. today. the ZOC is still to set the standards for the utmost musical fidelity in all respects considering a convincingly performed low frequency spectrum in subtle coloration.

They were specially developed for low frequency applications for which maximum performance fidelity. tonal neutrality and the smallest possible internal resistance are of primary importance. That way. these coils also enable the high efficiency of today’s High End loudspeakers to be optimally enhanced. even with low-output single-ended tube applications.

Moreover. we are pleased to present a completely revised and expanded model series. which now meets numerous customer requests for smaller dimensions. too.

The excellent qualities of the N series with its transparency and musical authenticity can yet be further enhanced by applying Baked Wire Treatment. Same applies for vacuum impregnated ZOCs made from copper round wires with larger conductor cross sections.

Baked Wire Treatment featuring coils are listed as BN in the following table. vacuum impregnated coils are marked VN.
