Copper foil inductor crossover coils (83)

Manufactured using high quality audiophile grade materials, these inductors are a perfect choice for use in passive crossover networks. Use Jantzen Audio, Mundorf or Dayton Audio Inductors in your next build! Available in copper foil air core, perfect layer air core, and laminated iron core.

Copper foil coils excel at high frequencies: their foil wrapping reduces the skin effect commonly found in wire coils, which leads to a more even distribution of the current. On top of that, these coils feature an air core, making them superior to all metal core coils as far as accurate pulse reproduction and freedom from distortion are concerned. They can be used in all areas; either as high pass filter in the middle frequency range, as bass coil (with large conductor cross section) or in correcting components (with thin wire cross section). Precision, dynamic, subtle tonal gradations, great detail and liveliness distinguish coils with air core from all others. Copper foil and air core combined make copper foil coils the ultimate choice for high quality speakers.
