    I had those drivers too about 27 years ago. The box on mine was smaller like a subwoofer but the speakers were the same. Foam rotted so many times i replaced it 3 times and the 4th time it got replaced with rubber surrounds

    i found this problem only in this teardown, It is interesting that you cannot hear it in your ear, because the speaker voice coil is centred with the spider and there are no unwanted acoustic distortions.
