Mundorf FERON-core I core coils
|
| |
I-core coils are high-performance bass
coils. FERON™, used as a core material,
is heat treated after production in a special
process. This gives FERON™ a crystal
lattice structure that has optimum magnetic
properties, offers the lowest loss values and
is very resistant to distortion. Their power
handling capacities are substantially higher
than those of current ferrite core coils while,
at the same time, they‘re smaller and less
expensive than transformer core coils.
All Coils of this type are produced from baked varnish wire. To read about the amazing benefits of baked varnish, click HERE!

Mundorf FERON-core I-core Copper Foil coils
|
| |
M-Coil Laminated Core Coils made from copper foil combine
both the low level output distortions and the low internal resistance
of Feron core coils with the high resolution and the great
dynamic properties of OFC copper foil.
They are highly suitable to be used in high quality mid frequency
crossovers within subwoofer applications. Furthermore, they are
distinguished by an excellent value for money ratio as well as
by their compact dimensions.

Mundorf FERON-core I-core Zero Ohm coils
|
| |
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 fi eld 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 effi ciency 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.
Some of the coils of this type (BN types) are produced from baked varnish wire. To read about the amazing benefits of baked varnish, click HERE!

Mundorf FERON-core I-core Zero Ohm, Foil coils
|
| |
Our Zero Ohm Coil (ZOC) made from copper foil impressively
combines the outstanding natural music performance of extremely
low ohm Feron ZOC cores with the finely detailed musical
texture and multifaceted richness of OFC copper foil.
These coils were specially developed for low frequency applications
which do not focus on maximum capacity, but rather
exceptional performance quality, micro-dynamics and outstanding
technical properties such as matching perfectly with
highly-effi cient loudspeakers specially designed for low-power,
single-ended tube-amplifiers.
Our Zero Ohm Coil (ZOC) made from silver foil combines the exceptional conductivity of silver foil with
the minimal internal resistance of Feron ZOC cores.
The exceptional acoustic qualities of the SFN series can yet be further enhanced by adding 1% of the
purest gold to making in the ultimate SGFN series.

M-Coil’s transformer-core coils combine
both lowest distortion rate and precise pulse
signal with low internal resistance, even
under highest output levels.Therefore they
have been the benchmark for extremely
precise and powerful but deep bass performance
for more than 25 years!
We are very pleased to present a completely
revised and expanded model series, now
meeting frequent customer requests for
smaller dimensions, too.
The outstanding features of this series can
be considerably enhanced yet by the appliance
of Baked Wiring Treatment or Vacuum
Impregnation.

foil combine both the natural dynamic fidelity
and typical tonal transparency of OFC foil
with the remarkable performance precision
of Feron core coils, particularly, at the lowest
frequency range.
