In an iron core inductor, a ferromagnetic core concentrates the magnetic field, so the same inductance needs far less wire, a smaller size and lower DCR. For high-value bass-section coils this is often the most practical solution.
The trade-off is that the core can saturate at high current, which causes distortion. For high-power systems choose a generously sized core, and where space allows, an air core remains the cleaner choice.
