Crossover Network Tuning
Our experience shows that high-quality crossover network components can get between 30% and 50%
more performance out of your speakers! Good crossovers don't cost all that much and they deliver radical
improvements, even in low-cost configurations. This was graphically demonstrated in a report in the
leading German hi-fi mag Klang & Ton (see quote below). In the "cheap trick" described in the K&T
article (154€ for the speaker pair) the great enhancement in listening pleasure provided by using highend
crossover components easily justified the additional cost of 77€, which is just one third of the
total final cost of the speakers. It would be difficult to find a better illustration of the crucial importance
and huge benefits of high-grade crossover components:
("The replacement...brought a really striking improvement in quality, particularly in mid range, high
range and overall presence. The new sound is completely natural, without any trace of 'loudspeaker'.
It's as though there were no more speakers you could identify as the source of the sound - what you
hear appears impressively disconnected from the physical speakers. Everyone who listened to the
results agreed that the enhancement to the sound fully justified the additional DM150 for two highend
crossovers.")
("In the high-end version the second capacitor in the crossover is a MKP metallised paper model
(C1, in parallel to the woofer). This component delivers a very perceptible improvement in the mid
range over the inexpensive electrolytic capacitor, demonstrating that even the parallel components in
a crossover have a real and significant influence on the sound.") Klang & Ton 4/98, p. 64 ff.
Having read this you're probably interested in the details of "our" recipe for tuning a crossover network for
optimum sound performance
• Air is by far the best coil core material. Use air coils wherever possible. But remember, when
you replace coils the new air coils must have the same low resistance (W rating) as the existing
(cored) coils. This is crucial!
• There's no alternative to coils with cores for applications calling for very high inductance values.
When you have no choice, coils with Aronit cores are definitely preferable to ferrite, provided
that their internal resistance is low enough.
• On the other hand, ferrite core coils are easier to install in cars than coils with Aronit cores.
• In the deep bass range there is ultimately no real alternative to transformer core coils and zero
resistance coils. They are the only designs that enable you to combine extremely high
inductance values with low resistance and exceptional power handling capacity.
• However, reducing the internal resistance of the bass coil is not always advisable as this also
changes the tuning of the system. As a basic rule of thumb you should only make this change if
you want to change the bass tuning, making the basses more "dry and precise". It's important to
understand that "dry" in this context also means "less" bass!
• All coils, including the coils wired in parallel to the speaker unit, should have baked varnish
windings (or vacuum impregnated windings with wire over 1.4mm thick).
• Install an MCAP Supreme directly upstream from the tweeter. This generally makes the sound
enormously more spatial and transparent.
• When very high capacitance is called for, for example in two-way configurations with a low
crossover frequency, you can save money by connecting an MCAP Supreme and an MCAP in
parallel. (The Supreme should contribute at least 30% to the total rating.)
• Mid-range: Connect an MCAP in series to the speaker unit.
• If possible, all parallel capacitors should be MCAPs, or at least MKT metallised plastic film
capacitors.
• At a pinch you can also use film capacitors and electrolytic capacitors connected in parallel for
the bass range.
• All resistors in the signal path and parallel to the tweeter should be metal oxide components.

• Install the crossover in its own separate housing or cast it in resin.
Send us your circuit diagram or your original crossover network. We'll be happy to send you a quotation.
If you want we can also install your high-end crossover for you!
Whichever solution you choose, we're sure that you'll be delighted with the results of your Mundorf tuning
project!

AIR CORED COILS
COILS
Air cored coils are, for physical reasons, unbeatable as far as accurate pulse reproduction
and freedom from distortion are concerned. For this reason, for all the purists, we stock air
cored coils with wire diameters of up to 3.0 mm. It is also possible in this way to create
greater inductances with relatively low internal resistance. Vacuum impregnation, which is
described in detail at the end of the chapter "Zero Ohm Coils", also leads in the air cored coils
described here to greater detail and spatial quality in the reproduction of music.

Air cored coils with baked varnish windings
Air cored coils are, for physical reasons, unbeatable as far as accurate pulse reproduction
and freedom from distortion are concerned The windings of baked varnish coils are made
using a special wire. After the coil has been wound it is heated up causing an additional layer
of varnish on the wire to melt, bonding the individual windings firmly together. The effect is
similar to that achieved with vacuum impregnation, but this process is cheaper for small
coils. Baked varnish coils are available with winding diameters from 0.71mm – 1.40mm. All
series are identified with a “b” prefix.

COPPER FOIL COILS
For some time we have been succesfully offering copper foil coils manufactured dy us of the
oxygen-free copper(OFC).
OFC is charecterised by ist special purity and the structure of the crystal lattice.
The electrical advantages of the design add themselves to the excellent sound characteristics
of this noble material. A winding is wound on a winding( not in layers at each other as in the
conventional coils),that`s why this design comes much closer to the physically ideal coil. This
expresses itself e.g. by the item that the coil stays constant till more than 100 kHz.Besides,
the undesirable capasitive part of the coil is especially small, so that even very high
frequencies (VHF) can be effectively blocked.

ARONIT Coil with Baked Varnish Windings
Aronit is a sintered metal material that is highly resistant to distortion even under very
extreme stresses. Together with specially designed bobbins this material makes it possible to
produce coils with extremely low resistance and excellent value for money. Aronit coils
are the ideal choice for all applications calling for high power and low distortion at a
reasonable cost.
The windings of baked varnish coils are made using a special wire. After the coil has been
wound it is heated up causing an additional layer of varnish on the wire to melt, bonding the
individual windings firmly together. The effect is similar to that achieved with vacuum
impregnation, but this process is cheaper for small coils. Baked varnish coils are available
with winding diameters from 0.71mm – 1.40mm. All series are identified with a “b” prefix (see
p. 23).

FERRITE DRUM CORE COILS
Our high-performance HP 3616 ferrite is the answer for many users’ need for an inexpensive,
high-power ferrite material. The mechanical advantages of these relatively small coils are
obvious, but it wasn’t until this new HP 3616 material became available that we could even
consider adding a ferrite core to our product line. This German-made ferrite offers a
significantly higher performance than the cheap Asian cores used in many other products.
The HP series combines excellent electrical and mechanical specifications with
relatively low unit costs.

ZERO OHM COIL
The zero ohm coil (ZOC) is a special form of transformer core coil. This is also made of
the top quality material FERON described in the chapter "Transformer Core Coils". In
the ZOC, an air gap is calibrated and adjusted by hand between the two laminated
cores (one I-shaped and one E-shaped). The air gap determines the inductivity of the
coil and demands great care in the manufacturing process. It must not be too small, as
saturation effects would otherwise occur at high loadings. The high production costs of
the ZOC, and thus its higher price, are always justified when maximum faithfulness in
pulse reproduction is required.

VACUUM IMPREGNATION & BAKED VARNISH COILS
In non-impregnated coils, vibration occurs as a result of the current flowing through the
coil. The microphonic effect, i.e. the conversion of mechanical into electric oscillations,
adds these oscillations back to the original signal as additional information. In this way,
details of the original signal are overlaid and rendered unrecognisable. The music loses
spatial quality and transparency. This process is prevented by vacuum impregnation.
In vacuum impregnation, the coil is first impregnated with a special lacquer under
vacuum. Because of the vacuum, this lacquer flows right into the innermost windings.
The lacquer is subsequently dried in an oven at 130 øC. Thus the whole coil is baked into
a very solid unit. The individual windings are prevented from vibrating and the original
signal remains uncorrupted.
Vacuum impregnation preserves musical details which give the music natural liveliness
and an excellent spatial quality. It is thus an important component for a really audiophile
reproduction of music.
The price for vacuum impregnation is € 8.40 per coil.
The windings of baked varnish coils are made using a special wire. After the coil has
been wound it is heated up causing an additional layer of varnish on the wire to melt,
bonding the individual windings firmly together. The effect is similar to that achieved with
vacuum impregnation, but this process is cheaper for small coils. Baked varnish coils
are available with winding diameters from 0.71mm – 1.40mm. All series are identified
with a “b” prefix.

MCAP-SUPREME
CAPACITORS
The M-CAP SUPREME has been internationally acclaimed as the ultimate high-end capacitor.
Its outstanding sound performance is achieved with a unique combination of advanced
technologies:
• Special induction-free winding technology: Two capacitor windings are interleaved so
that their inductances effectively cancel each other out. These two windings are connected
in series. This means that it takes two 2µF windings to make a single 1µF M-CAP
SUPREME capacitor – the same amount that it would take to produce a full 4µF of
capacity using conventional technology!
• Best available materials: The polypropylene film used for the M-CAP SUPREME has
exceptionally low loss characteristics.
• Sturdy plastic and aluminium cases: This prevents microphone effect feedback, thus
protecting important signal details.
• The resulting listening experience more than justifies all the effort we put into the
M-CAP SUPREME. No other capacitor delivers a more spatial sound with such
perfect reproduction of the finest musical nuances.
No matter where you use the M-CAP SUPREME – as a coupling capacitor in your CD player
or amplifier, or in the crossover of your speakers – you always get the same surprising and
impressive performance. This capacitor mobilises such unbelievable reserves in your sound
system that it is really justified to speak of a new dimension of music reproduction.
Furthermore, the effect is not only achieved with very expensive high-end components. It
delivers a significant enhancement in more price-conscious configurations, making it a very
worthwhile upgrade. (Review: Klang & Ton 4/98, p. 68)

CAPZN
The M-CAP ZN is a tinfoil capacitor of the highest class. Solid tinfoil, together with high grade
polypropylene as dielectric, are used in its manufacture. This massive tin layer improves the
sound properties in unexpected ways:
Because of the great weight of the tinfoil and the resulting mass inertia, oscillation of the foil
and the accompanying microphonic effect are effectively prevented. Similarly to the vacuum
impregnation which we provide for choke coils, this fact leads to an increase in transparency
and spatial quality.
The loss angle tan δ at 1 kHz is ten times smaller than that for a normal MKP* capacitor. It is
only 0.00002 at 1 kHz and a mere 0.00001 at 10 kHz. This makes this capacitor incredibly
quick and lively. Both of these mean a genuine innovation. The M-CAP ZN is a milestone on
the road to perfect music reproduction!

MCAP
The M-CAP is an audiophile metallized polypropylene capacitor. In selection of the materials
used, special attention was given to the sound properties. Great care taken during the
production guarantees constant high quality and minimum electrical and mechanical
tolerances. Thus, in the final inspection, maximum deviations in capacitance of 1.5 % are
measured, so the guaranteed value of 3 % is far exceeded. The practically induction-free type
of construction and the low loss factor of the M-CAP results in a very "quick" capacitor. The
M-CAP forms the basis for vivid music reproduction rich in nuance.
The 630 V DC version with capacitances in the range from 0.1 µF to 0.82 µF is equally
suitable as a bypass capacitor in high quality frequency crossovers or as a coupling
capacitance in valve and transistor amplifiers.

MKT FILM CAPACITORS
MKT capacitors are metallized polyesther flim capacitors. They range both in price and
in quality between the low-loss M-CAP and the inexpensive bipolar electrolytic
capacitors. The loss factor of an MKT capacitor is about 20 times that of an M-CAP, but
less than a tenth of the loss factor of a bipolar electrolytic capacitor. (Loss factor M-
CAP: 0.0002, MKT:

BIPOLAR ELECTROLYTIC CAPACITORS
A distinction is made in bipolar electrolytic capacitors between two construction types,
"rough" and "smooth". "Rough" and "smooth" refer to the aluminium foil used for the
winding of the capacitor. In the rough type the foil is roughened to increase the surface
area of the foil. As the capacitance of a capacitor is proportional to the surface area,
larger capacitances can be achieved in this way with the same material costs. This
material saving is at the expense of slightly poorer electrical values. The construction
size of rough electrolytic capacitors is significantly smaller. Thus, capacitances of up to
800 µF are available in the BR63 Series.
Bipolar electrolytic capacitors are used where large capacitances are required cheaply
(series resonant circuits, impedance linearisation, etc.) or where foil capacitors (M-
CAP, MKT) are rejected for cost reasons. The higher dielectric strength of the rough
type also permits their use where smooth electrolytic capacitors are not surge-proof
enough and more expensive foil capacitors are out of the question.

METAL OXIDE FILM RESISTORS MR4 & MR 10
In contrast to normal wire resistors, metal oxide film resistors exihibit no residual inductivity.
Therefore, in all cases where impulse velocity is important, in the middle range for example,
metal oxide film resistors should always be chosen. The design wich we supply has a
continuous load capacity of 4 Watt, but can handle a much higher load in the impulse range.

Terminals and copper bindind posts
The terminals are availible in brass.
The binding posts are availible in brass or even in
copper.
Both items are manufactured with high mechanical
precision.
A gold plated version is also possible. On the other
hand, the gold plating needs an extra metal
between copper and gold, so there are three
metals copper, nickel, gold. Every border between
two metals is a source of thermical voltage, which
causes extra noise. So for purist the not gold
plated terminals are the better ones, even if you
have to clean them from time to time. But this only
for the purists, for marketing its always good to
have anything gold plated……..;-)
