Mundorf Hepta Strand coils

MCoil Hepta Strand coils unite the tonal clarity beauty and distortion-free performance of air core coils with the stereophonic spaciousness of tightly-wound coils. alongside the harmonious-warmth and splendid brightness of strand copper wire.

They are therefore the first choice for high quality high and mid frequency applications which focus on a finely detailed utmost refined musical fidelity performed within a truly holographic life-like staging.

Please note: The power values Pmax in the following tables were determined at 20 degrees Celsius ambient temperature and free convection. They are just a guideline and - since we are not the manufacturers - cannot be guaranteed by us.
