Tweak,
I would think that a magnetic material such as steel would not be ideal for placing around crossover components, especially air-core inductors. That would definitely interact with the magnetic fields produced by the inductors, in unpredictable and probably deleterious ways. Non-magnetics would be preferable IMO.
