MCoil CFC7 AirCore
AirCore Coil, 70mm XL foil
Their unique performance quality unites the tonal virtues of OFC Copper foil with the clarity and precision generally typical for all air core coils, alongside the authenticity of a tightly cemented reel which is practically microphonic-free. For High-End mid and high frequency applications, they are particularly distinguished by their 3D-like staging, their harmoniously-dynamic vitality and detailed performance. If you want truly distortion-free but milti-faceted and all-musical beauty, you may consider copper foil coils as first choice for your bass coils.
