High-purity copper wire wound around a Permite core + discs.
Extremely low DCR which does not alter driver damping factor and add to loss of efficiency.

The Permite material provides significant lower hysteresis compared to coils with ferrite cores, at the same time delivering higher power handling.

Generally only recommended for bass & mid section on crossover.

Power handling capability is determined by core/disc size and wire thickness.

We use 4N copper wire for Iron Core Coils + Discs
