No, that is not how speakers work at all. In a single speaker installation, speaker polarity makes absolutely no difference at all. with multiple speakers It only matters that they are all in phase. As the speakers are fed with an alternating current audio waveform, they neither push nor pull, or they both push and pull equally, depending how you look at it.

CORRECT! And thank's.
Not sure why people can't find anything better to all day than smash other peoples good ideas when all they are trying to do is help.. This technique has worked on my personal evo my wife's and 2 friends, if you don't want to try it, great, don't. But quit trying to make it sound impossable/dangerous to the average Joe, cause it's not.

I'm a machinist, and every few days I pull my batt cover and see that my speaker is COVERED with chips. I use a magnet and it works just fine.

Thanks for posting this for everybody

I think this is not plaguing my ear piece speaker. But I think it's much harder to get to the front speaker then the back. :/

Anyone have a link to a good video for removing the speaker?

And I'm not sure if I'm still under warranty, I got my EVO on launch day, so I think I'm just recently beyond the 1year warranty aren't I?

I may be doing one for a friend of a friend, if so I will see if I can shoot some footage.
Otherwise your good friend Google or YouTube.

My speaker has managed to mess up three times in under a year and yes it was because of metal shavings on the speaker. I'm a driveshaft mechanic and work with metals and tubes and such an my evo's speaker is messed up now. I didn't want to buy another speaker since the first time I took it to sprint the charged me $35 and fixed it on the spot. The second time I got to speakers from ebay for under $15 so i replaced them my self. I was going to add a little mesh inside the back cover of the speaker holes so no more metal shavings would go in but never did it. I was going to take it off my nexus one back cover. Now I have to try this I'm always taking off the metal shavings with and earth magnet but i haven't don't it since I gave up on fixing this problem and yes I hate the nasty sound it makes. Lol

I will give this a try to see if I can fix it. I thought I was thinking only one having this problem. Lol

its one screw further... basically do all of the steps to get to the speaker, then in the top right you will see a small Phillips screw, unscrew that, then the board comes up from the front housing, be careful cause the cables are still connected on the left. once you have the board pulled up to the left, take the little power button at the top out of the housing as it makes it easier to take out the earpiece. now you will need something small to pry the earpiece up from the top left of the earpiece (where you just removed the power button from, be careful you dont wanna break the earpiece). do the same thing with the magnets on this earpiece, make sure you get all the metal shavings off.

Then just do those steps in reverse ( be careful not to break the vol up / down buttons when putting the board back in ), also when putting the board back in there is a little tab on the left that a part of the board has to go under to go back on right, make sure to screw the phillips screw back in the top right too.

should be good after that. i might do a video tomorrow at work... i have to do this almost every day.
