I took out the TangBand W5 out of the bedroom 3 way to do some tests
I found this strange washer attached to the magnet. Is this part of the driver somehow....?
It looks brass but is magnetic. I have hundreds of washer types in my shop but none of them look like this.

The brass is likely EG steel. Every once is a while a rebel wants out of the confines of the factory and becomes a castaway aboard the good ship barium ferrite. Probably nothing more.

I can understand piggybacking further magnets but a tiny washer like that? Why wouldn’t they simply center the magnet? I think we have the technology for that.
Depending on the magnetic field it should 'center' itself. You think that they would have used ball bearings for this.
...Ok, ok, I can't do this. Are we all joking, or is it just me?

A little googling finds you some interesting info. Off centre ferrite magnets are more of a visual concern than electrical and are thought of as no big deal up to a point. As long as it’s working properly…
Ixnay, with what we read in some threads, I am never sure who is joking.
It should have been obvious.
Cheers.

I figured it as about 50/50. Since I haven't ever taken a driver apart I don't really know if there washers anywhere inside
I have never taken a driver apart, but UPS did it for me once upon a time. No washers found at the scene.
But you know, That idea that I have about the ball bearings might have to be used for hi-end. Of course, one could opt for the more expensive MKII, which would be tapered bearings. On almost a more serious quest, what would happen if iron powder were put into a plastic bag and placed on the rear of the magnet? I mean, under a certain condition would they make a pattern? I know they wouldn't but my mind won't let me stop and smell the roses.

Higly probable this washer has nothing to do with flawed TB quality control. Instead I guess it stems from your bedroom clutter. My advice would be to consult your cardiologist immediately, and don't forget to bring this washer along with you: These kind of washers are widespreadly used for the implacement securing bolts of pacemakers. Rarely, but typically these can get loose (and lost) while nightly inconscious chest scratching. And beware of DIY: Don't try to refit it by yourself, by no means !!!
No joking.

In my classic VW restoration experience, compressible 'copper' sealing washers started to become suspiciously magnetic a couple of decades ago...
Now that's a serious cut-back. But going from stainless steel to EG would save money. The patient might not like the extra zinc but what the heck, it's such a thin layer, and besides he already has a bad heart.

This is what I initially thought it was from but no, all of the hardware on the back is true brass where this is ferrite. Oh well, I guess it will forever remain a mystery
Why do you say its a strange washer ?
It looks like a perfectly normal washer to me.
Round, with a round hole centrally located.
