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’ve used different strength of double adhesive cutting it to shape, it doesn’t matter they are all broken. 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. 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.Ĭame 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 thought to give my contribution to this post, because I had to replace the right speaker. Just press the plastic structure of the speaker. Of course don’t press directly on the “sub” speaker. To have the best contact between the speaker and the structure.īefore doing anything you can try with a sound: just play on the new speaker a sound like low voice (you will ear better this distorsion with low medium frequency than very low frequency)Īnd just press on the speaker, the distorsion will disapear. You can manage it to keep this really really thin adhesive surface at the same place it was originally.Īfter that you just put the new speaker and press it in its cabinet… but really press it a LOT !!!! You have too keep the best way you can the original adhesive on the mac structure when you leave the speaker. I had this blown sound on my replaced left speaker too, I fixed it again. I replaced mine because of the same issue you had (and obviously I know that will happen again sadly) If you have a semi contact between the speaker and its cabinet you will have distorsion too. If you have too much adhesive tape between the speaker and its “cabinet” you will have distorsion It grows when you lower the frequency because it’s ringing the structure of the speaker with the mac structure.
