Additional Layer of Paper — Decoupling Layer in the Wrap

Additional layers of paper in the wrap act as dedicated damping and decoupling layers between individual winding areas. They prevent larger coil assemblies from resonating as a rigid whole and deliberately fragment the vibration behavior: Instead of a single large, long-decaying eigenmode, many smaller, faster-decaying motions are produced. As a result, the tendency to develop pronounced self-resonances decreases, and the component reacts less sensitively to mechanical stimulation — both from the housing itself and from loudspeaker vibrations and coupled in structure-borne noise.

This effect is particularly decisive for high levels or complex music signals: When large wrapping areas no longer “act together“, the resonance behavior remains controlled and predictable. The sound image appears more ordered because critical resonance peaks no longer emerge as dominant, tonal artifacts, but are broken down into inconspicuous, short-lived movements. Here too, the selection of the right paper — in terms of fiber blend, density and hardness — is not a coincidence, but the result of deep understanding and extensive experience. Only the right combination of position, paper quality and winding structure results in a component that is mechanically stabilized without losing openness and audibility.

Tonal effects

• Larger wrapping areas no longer resonate as a whole; critical frequency ranges remain sound-ordered.
• The base and lower midtones create a calm, controlled impression, even with complex music signals.
• Roar, rocking and “hollow” resonances are significantly reduced — the loudspeaker appears tamed without being braked.
• Instruments with a strong base tone (voices, piano, woodwinds) appear rounder and more credible without becoming dull.
