I thought to give my contribution to this post, because I had to replace the right speaker.
Went thru 6 different suppliers because of different faults (either weak tweeter to blown woofer) all of them provided to me with glue residue , either on the frame or on the connector itself, also analysing the pictures on amazon they all have old glue.
Came to the conclusion that none of this speakers are brand new but just pulls from top cases, and altho yes the aluminium acts partly for resonance (like a transducer on a wood board) and transfer the lower frequencies , most of these woofers are mechanically flawed because if you send a low volume sine wave it should slowly oscillate not cracking straight away..
I suppose the demand of new speakers (due to the blowing issue) is higher than supply , then from mainstream channels you get all the pulled one.
I’ve used different strength of double adhesive cutting it to shape, it doesn’t matter they are all broken.
If air escapes from the lower part (the most crucial as the tweeter doesn’t need to be airtight) yes you could have unwanted movement from the woofer flat cone, but not to the point of crackling at low volume, it’s just insane..
-I also think that
+I also think that Apple with this model has pushed to far the sub frequencies , considering the size of the woofer..
So get your money back, and hopefully you will find one of acceptable quality that doesn’t crack as before and install a general EQ app like https://bitgapp.com/eqmac/ to kill the global lower frequencies and have a sound comparable to the old retina A1398.
I hope to find a decent replacement in the future, in the mean time I have stereo sound!
