Jantzen Audio air coil 1.3mH / dr.0.3mm
Jantzen Audio Air Coil The ideal coil core material is air. Air core coils are, for physical reasons, superior to all metal core coils in terms of accurate pulse reproduction and lack of distortion. They can be used in all areas in passive crossovers, in the tweeter filter, in the mid-range and as a bass coil (large wire cross-section) or in correction elements (RLC) (fine wire cross-section). Precision, dynamics, subtle tonal gradations, great detail and durability distinguish air core coils from all others. Therefore, in loudspeakers, they constitute the basis for the realistic and harmonic sound of music.
The high purity of the copper wire and its "tight" winding allow you to create a coil without saturation distortions, minimize DCR and ensure the absence of hysteresis.

All coils are made to order. We offer over 4,000 coils for loudspeaker crossovers. Coils play an important role in loudspeaker crossovers. Inductors do not change the character of the sound in the same direct way as changing capacitors. The role of coils has more to do with efficiency, power transfer and increasing the dynamics of the sound by choosing the right type of coil. As long as the coil is well made of high quality copper, the signal paths will be as they should be. What does it take to get a good audio-grade coil? The most important factor for a good quality inductor is that the copper used is of certified good quality, such as the ETP (Electrolytic-Tough-Pitch) C11000 copper that we use in Jantzen Audio grade copper. Above this class there are no technical advantages and the improvement in sound quality is not proportional to the price. Using a higher grade of copper would make the coils more expensive than necessary.
In addition, winding integrity is a very important factor. At Jantzen Audio, we wind our induction coils (wire or foil) on semi-automatic machines and use "sintered wire" technology to produce wire coils without the need for bobbin stiffening. For foil coils, we have built our own special semi-automatic machines that allow for tight winding and full control of the application of layers and insulation.
