Has anyone received the speaker shield yet?

I've ordered the speaker shield a few months back, yet I haven't got anything in my mailbox.

Why haven't you already fixed this issue on your own, instead of waiting for 6 months?
The repairkit consists only of a metal foil and a double stick tape! Both you can buy in every do-it-yourself store for little money!

What kind of metal works like a shield? alumnium doesn't work.

Onyx promised me that "I will receive it within a few weeks" and it was the main reason why I was still waiting.

Aluminum would shield electromagnetic fields. Here the problem is caused by magnetic fields of the speaker, so you need an metal with a high magnetic permeability.
Just proof if the metal foil is magnetic or not. If an magnet attracts the foil, so it will shield magnetic fields.

Would not such a foil itself get magnetized evenually and need to be replaced?

It depends on the shielding material. I don't think the commercial shielding materials (like mumetal) have this problem. Google for "mu metal foil" or "mumetal" and you'll find plenty of information on the stuff.

If you just use a piece of soft iron, then you would probably magnetize it eventually.

I've searched mumetal, and they have to be ordered at least 1 foot long for $44 USD. oops.

The alumnium doesn't work, according to some website, but I'll give it a kick see how things go.

If a magnet won't stick to it, it won't work. So, rather than aluminium or other non-magnetic metals, try some iron, steel or nickel sheets if you have them. They won't be as good as mumetal, but at least they'll shield some of the magnetic fields. Maybe it'll be good enough.
