    Testing for blown speakers?

    My music has been rather crackly lately in the right speaker. Is there any way I can test if its blown out for sure?

    Thanks

    Hmmm. If there's no sound then there's something wrong. Hehehe.

    Seriously, what do you mean? Are you concerned with the degradation of the quality of the sound that comes out of your speakers? It's hard to quantify that unless you have discerning ears.

    My music has sounded a bit harsh lately. I can't listen to music for prolonged periods without straining my ears. I hear crackling on certain songs.

    Plus when the crowd chants in Football Manager, I get a crackly noise along with it. I'm 100% sure it wasn't like that before so I was hoping there was a way to test if they're blown out or something.

    Hmm. Haven't experienced that. If you're sure the sound wasn't like that before, have you tried a reset of your Mac? Or if you haven't restarted your Mac for quite a while now, can you try restarting?

    These may be farfetched but i can't think of any reason why the speakers would sound worse.

    Hold on, did you install a 3rd-party app that's supposed to improve your speakers' sounds? I remembered there's one like that, like an equalizer or something. I tried installing it but it just made the sound worse. I had a hard time uninstalling it so i ended up reinstalling from a Time Machine backup.

    Of course I've restarted. Even the startup tone makes the speaker crackle. I honestly think its blown out, but I just wanna test for sure as I don't have time to bring it to a service center right now.

    Topcase replacement in early November. Then case alignment a week after that. Still needs to be sent back over another issue. Why?

    Its there even with the YM beeps though. :slanted:

    Did you notice the problem right after the topcase was replaced or after the case was aligned?
    I am thinking that when they replaced the top case and transplanted the speakers fro the old topcase, something might have happened to the speaker.

    This is what the right speaker looks like - http://s1.guide-images.ifixit.com/igi/lEwtQaO54ExHaQEU.large

    nothing. because the last time i went at DH to replaced my trackpad before my warranty expired, i encounter minute issues on my mbp days after it was returned to me. 1st is about my right speaker then 2nd is the led of the power on my mbp. i discovered that the wire on my right speaker is not plug correctly and was on loosed as to the led, it was detached from its socket. try checking the wires attached on the socket. sometimes, it was not fitted properly. :)

    btw, the right speaker is located beside the superdrive. the black one. on the left, it is the last wire on the lower right, if you are facing you mbp upside down, battery at the bottom. :) hope this could help. if non of this work, better yet return you unit to the service center. :)

    Nope. The speakers actually sounded clearer after my topcase was replaced. Now the right one can get crackly.

    I don't really wanna open it up myself. Haha! Thanks for the suggestion though.

    So, is there seriously no way I can test the speakers? Maybe play a specific file or something?

    The easiest way is to play the same mp3 on a different unit and compare.

    maybe you'd want to download some files from denon (i think) they have those speaker test tracks. :)

    although they're quite hard to find... pm'd you.

    ok i understand. i don't any apps that could test your speakers. on my case i do it manually, the typical observation. hehehe. wait, could the apple hardware test do its trick? did you try running it?

    I don't have access to another 15" MBP though. If I wanted to test it properly that way, I'd have to run 2 machines with the same speakers or else they'll really sound different. But thanks for the suggestion.

    These might be exactly what I was looking for. Got your PM, thanks!

    Yup, I was hoping to do it through observation. Haven't run the hardware test, but I'm not sure if they can test speakers there.
