High-purity copper wire wound around a Permite core, for a high inductance at the lowest cost.
Extremely low DCR which does not alter driver damping factor and loss of efficiency.
The Permite material provides significant lower hysteresis compared to coils with ferrite cores, at the same time delivering higher power handling than the ferrite ones.
Generally only recommended for bass & mid section on crossover.
Power handling capability is determined by core size and wire thickness.
The greater the core size and the thicker the wire, the higher the power handling capability will be.
