Nastly little magnetic tweeter/mids ?
As a 47uF NP cap is over one, for mid?
Anyway nasty buzzing overtone as though a bit of steel swarf or staple
has got on the cone of a larger speaker.
These things have brushed aluminium inverse dome covers on them, do they
work loose, swarf dislodged inside?
Of course close-handling has "cured" the problem, but bound to return
without proper treatment




You also might want to remount said speaker with that recommended to tighten
cylinder head bolts, so it's flimsy chassis does not warp in the process.

Though I would guess you are very aware of this method already.
