This was quite shocking actual, opened a well known manufacturer's speaker and found questable workmanship. I set off to repaint this center mtm and removed the baffle/divers, which only required a few minutes. One other reason I opened it there was low pitch vibration with a gentle hand/palm hit test.
The following was shocking, when I removed a mid woofer, the large heavy "bell" was loose and popped off, with the add-on double magnet stuck to it. The glue they used did not hold at all on the back of the speaker-basket and only slightly on add-on magnet. The bell-crown was only glued at the crown, no rubber gasket around the bottom edge.
Fixes:
J weld the magnet back on the speaker
Add construction adhesive to the rear on the double magnet
Window foam insulation to remove the ringing
I will never buy another speaker from this company. It was engineered and assembled intelligently, everything but the last step!
note second pic, no adhesive on the wide surface, only a dap at the center.

I experienced a similar scenario several years ago,
And it is rather shocking. But I’m afraid a lot more common than I realized.
It was on a pair of Wharfdale speakers from a boutique type store. The damn things began rattling internally and on inspection I found a broken crossover board. I was incredulous. I will never buy a Wharfdale product ever again. I realize there are many reasons this could happen but geez, these speakers were not cheap. Makes you wonder

First step completed, JB epoxied one of the loose magnets with a temporary hardware bolt, nut, washer, tape. Thinking about not reinstalling the metal caps, hopefully they are magnetic shields (only) and not there to strengthen the field. ugh
Still scratching my head, this was not a inexpensive center speaker.
Plus 1 DIY for speaker building!

Do you still have the Wharfdales? I never had the pleasure to listen to a pair. I reached a stopping point for now, a tweeter problem, should be resolved in a couple of weeks. I really wanted to move the drivers out flush to the front of the baffle and use wood instead of the original plastic (wood replacement shown in photo). Also epoxied the magnets back on, which were simply glued to the metal back of the galvanized steel, or something similar; the tweeter was also done in the same fashion.
