I’ve found potential replacement speakers here. They look fairly similar to the ones in the A40s, but the resistance value marked on the speakers in the guide vs on the listing is different.

Buyer caution must be taken before actually making the plunge, as sound quality might be different. The listing is from Ali Express after all.

Great so far but how do you actually remove the speaker/driver from the plastic casing without destroying the plastic parts, since it seems to be bonded or glued-in?
