Speaker Cones

[Kestasme]

Is it possible that after countless hours of being exposed to low Bass songs(That have hums anywhere from 80Hz down to 30Hz AKA Electro,Trance) the cone becomes more loose, and therefore reproduces the low end even better? I have been playing songs like that on my 9000Z for over 20 Hours and the left cone Seems to move a lot more than the right one, they moved the same when i got the box. The left one is more loose, like if a tone makes the dust cap move about 0.6Cm, then the left dust cap will move over 1Cm.
Short Version: Is it possible that speakers exposed for long periods of time to Low end bass music become more flexible?

I doubt it. The voice coils float so that should add no drag. If you are talking surrounds, a looser one might allow it to vibrate at faster rate without dampening the music but the actual amount of excursion should not change. There is probably an electrical reason for the difference in excursion. I am guessing that if you were to separately poll the L/R channels, that the one with greater excursion will be louder.

in most cases speaker require a burn in period at the factory , this insures power handling and suspension travel ,but in most cases over time and if you put continuous hours of play on the speakers they will tend to become looser or more compliant , depending on how many hours are on the speakers .

speakers that are used more on again off again than Continuously never really burn in because they are not exposed to power input and excursion as often ,so driving un broken in speakers causes distortion which causes damage to the voice coils and from there on sound like crap .

most speakers must be burned in using a sine wave and white noise for 24 hours with full rated power input peaks that stress the speaker and confirm power handling specs.

Except.......GF-9000.......... 35 years old. Seems to me at this point, the surounds are more likely to start cracking and vaporizing than they would to finally begin breaking in. In any event, as to the question regarding the amount of excursion, one channel being louder than the other is very common and it could be as simple as oxidation accumulating on switches, controls, record bar.... etc.

I mean, it's not like the STEREO boombox was operated on one speaker it's entire life. So thinking one side would break in more than the other just isn't really plausible.

not saying it is , just saying that's how speakers are broken in ,hell it could be that it needs new speakers or a good cleaning you know the usual suspects

and another lesser known fact about stereo sound is that one side sounds different from the other thus less bass on one side and more on the other and so on so if one side has less bass its the stereo effect not the speakers if both sides sounded the same it would just be mono would it not ?.

Thanks for the awnsers. The box might indeed be over 30 years old, but it was only played on low volumes for radio,for the old folks that used to own it. It wasnt exposed to volumes above 1, yes 1 out of 10. Well if they got it in 1989 and listened to it in the morning for 30mins-1hr before going to work then i dont think the speaker suffered any major excursion damage or so.
P.S The box still rapes my M70 and or Crown 980 at 100% volume in bass, it really does. Althou it does it not by using deep bass, but it kicks like a mad giraffe with those magnets.[ And yes it has WHITE woofers].
