The sound characteristics of a coil are not only determined by the coil core and the manufacturing quality but also by the wire type used. In order to be able to offer you the right coil for each application we use three types of wires made of three materials of highest purity.OFC copper Coils that use oxygen-free copper (99.997% purity) as conductor material are characterised by a harmonic, stereophonic reproduction of music, rich in detail, and an excellent price/performance ratio.Pure silver Due to their ability to reproduce voices and instruments in a more dynamic, detailed, spatial manner and with more timbres compared to copper coils, silver coils of highest purity (type 99.99%) are highly appreciated and preferred by a number of audio enthusiasts.SilverGold 99% silver + 1% gold = 100% music. This does not only add up for capacitors such as the MCap® SUPREME SilverGold.Oil and audio cables, but also for coils. The high-purity gold (type 99.99%) changes the crystalline structure of silver and maximises its very good electric conductivity. Instruments and voices unfold their full range of timbres and their character is illuminated and becomes perceivable in all shades. On the one hand `crystal clear,´ the reproduction is at the same time vibrant and warm, embedded in a finely differentiated, location-true image. Purity and fine elegance combined with a vibrant character distinguish this exquisite material from all others!SolidCore wires The reproduction of music by coils made of solid round wires (also referred to as SolidCore) excels by natural vibrancy and fineness as well as highest tonal neutrality. Another benefit of round wire coils are their highly compact dimensions. Like all Mundorf coils, they are wound and mounted by hand with highest accuracy and precision using special machines in Germany.OFC standard is the most cost-efficient, audio-compatible coil wire and available in diameters from 0.50 to 3.90mm. Coils made of this material, however, do not have an additional coil fixation and thus have a disadvantage with respect to sound compared to all other coil types manufactured by Mundorf: This is because electric current passing through a coil will always cause a vibration of the entire winding. Due to the microphonic effect (the conversion of mechanical oscillations to electric oscillations) these mechanical oscillations are added to the original signal as additional information. This results in an interference with and an alienation of the details of the original signal. On the one hand, this results in a loss of spatial quality and transparency of the music and on the other hand in an increase of distortions and tonal discolorations of the signal. This physically induced unwanted effect, however, can be eliminated completely by the use of baked varnish wire or by means of vacuum impregnation.Baked varnish coils have a special, solid OFC round wire with an additional layer of varnish. After the coil has been wound, it is heated up by means of an electric impulse causing the additional layer to melt. When cooling down, the individual windings are firmly bonded together by the baked varnish and are thus prevented from vibrating and the original signal remains uncorrupted. Unfortunately, self-bonding wires are only available in diameters from 0.50 to 1.40mm.Vacuum impregnation is another procedure, equally effective as heat bonding, which we offer for coils with larger wire diameters (2.00 to 3.90mm). In vacuum impregnation, the coil is first impregnated with a special lacquer up to the innermost windings under vacuum. Subsequently, the impregnated coil is dried at 130° Celsius. Thus the whole coil is baked into a very solid unit.

    FERRIT Core Coils

    MCoil Drum core

    MCoil Drum-Core coils made from oxygenfree copper (OFC) round-wire have been developed for mid, low and parallel applications for which compact dimensions, a low basic distortion level as well as the lowest possible internal resistance and a reasonable value for money ratio are of key importance.

    The tonal quality of these coils is a convincing blend of the typical harmoniously-neutral sound of solid core copper round-wire and the natural vitality and enhanced tonal dynamic of HP3616.

    The fine properties of the H series can be further improved by applying Baked Wire Treatment as introduced with BH series.

    ARONIT Core coils

    MCoil Rod core coils

    Aronit cores (also known as P cores) consist of high-density metal-ceramics-powder. The German- made Wicon ferrite rods produce extremely low distortion, even at very high loadings. Due to their highly compact dimensions, their low internal resistance and their excellent price/performance ratio they are particularly suitable as bass and subwoofer coils and for PA applications.

    MCoil Rod core coils combine the balanced, detailed and dynamic tone colour of OFC round wire with the low output distortions and internal resistance of Aronit cores. They are therefore an excellent choice for good value and compact yet high-capacity middle-low and low frequency coils, including for PA applications. The great features of line A as well as the transparent and undistorted music reproduction can be enhanced even further in line BA by using self-bonding wire.

  • Jantzen C-Coil - Toroidal Core

    C-Coil is wound around a sandwich core, and it has extremely low resistance and can shift a large amount of power without getting over heated.

    The core is formed like a donut with a round cross section, and it is wound from one long piece of laminated steel tape.
    The surface of the core is epoxy coated to secure against short circuit even at a very high load.

    We have tested the inductor with a carrying load of 1000 Watt, and it lasted and stood up well.
    It can stand upto 700 Watt per 48 hrs in one go.

    We are very satisfied with the result.
    The C-Coil is designed for Bass, Sub-Woofer and Amplifiers, in different core and wire sizes.

    Please note!

    The C-Coil cannot be measured using a universal LC meter. Due to the characteristics of the core and winding method, it is important to use a professional RLC meter. We measure all C-Coils before shipping them using a professional RCL meter at AC 1 V 1 kHz.

  • Jantzen Audio Cross Coil

    The Cross Coil has been developed in cooperation with Audio Technology, Denmark, producing high-end drivers for the world market.

    No chain is stronger than its weakest link. This is especially so when we speak of loudspeakers, where there is often a cost reduction for crossover inductors. The result is distortion and power loss.

    High-end loudspeaker producers overcome this problem by using foil coils, where the copper is flat instead of round.

    Cross Coils are available in 12, 14 and 16 AWG.

    On special request we can also offer Cross Coils in 8 AWG

    The Permite material provides significant lower hysteresis compared to coils with ferrite cores, at the same time delivering higher power handling than the ferrite ones.

  • Jantzen Audio Litz Wire Wax Coil

    Jantzen Audio Litz Wire Wax Coil

    The Litz Wire Wax Coil offers reduced skin effect and lowered resistance, compared to conventional wire based inductors, which in turn offers more dynamic head room and clearer sound.

    We have impregnated our Litz Wire Coils in the same high quality wax used for the Wax Coil.

    Making the Litz Wire Coils wax impregnated offers a much firmer coil and secures the windings in place (eliminating microphonic effect).
