Zero Ohm coil N300 vakuum impregnated VN125 VN140 VN180 VN236 VN300 VN390 with foil CFN14

Mundorf Zero Ohm Coil (Mcoil N)

Mundorf Zero Ohm Coil (Mcoil N)
Enlarge
Our Zero-Ohm-Coil (Mcoil N) not only is a remarkable milestone in Mundorfs +25 years lasting company history but certainly a true milestone within the field of audiophile coil technology in general. 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.

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 Zero-Ohm-Coils 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.

Please note: The power values Pmax in the following tables were determined at 20 degrees Celsius ambient temperature and free convection. They are just a guideline and - since we are not the manufacturers - cannot be guaranteed by us.
