Question about Harman Kardon iSub Computer Speakers

1 year old iMac speaker buzzes and sounds distorted

During the last 3 months I've noticed that my iMac speakers sound tinny and fuzzy, especially during low tone playback of music.  I took it to the Genius Bar and when the tech checked it out to my surprise we couldn't hear the buzzing.  Made me look crazy!  I brought it home, fired up iTunes and immediately the blown out speaker vibrating resumed.  I've moved the iMac to a different location in my room and placed padding below the unit; however the distortion persists.  Is it possible that the environment at the Genius Bar (i.e. large, open air store setting with lots of background noise) made it impossible to detect the distortion I've been experiencing at home.  Also, is this a driver issue or the speaker hardware itself?  Any suggestions or recommendations would be greatly appreciated.

    the same happened with my speakers too. It only sounds that way when I play a song with a low base note in it. It has the same sound as a blown car speaker.

    Have the same problem on a brand new 2009 iMac - distortion only on left side speaker. Right side is allways crisp.
    Will try my Apple Care plan to get the left speaker replaced and see how that goes...

42.1i passenger side rear has power but sound is very quiet and tinny. all 3 other speakers work fine.


It sounds like the woofer part of the speaker is bad, while the tweeter is still good. You are going to have to replace the speaker. Speakers are generally sold in pairs, so it would be best to replace both rear speakers at the same time.

I have a RZC 298W RCA FM/AM tuner/stereo amplifier that I cant find anywhere. It works ok, except its fuzzy. I'm Just curious about schematics and what year it is. it looks like its at least 40 years old....


You could contact a tv repair shop, many shops have schematics that go back many years. You say the sound is fuzzy, is this fuzzy sound when your playing the radio or when you play something throgh the amplifer? If its fuzzy with any source the you might have a bad speaker or speakers. you need to be more discriptive of the fuzzy sound you describe. also. if this unit has a head phone jack, (which I doubt if its 40 years old). you could plug in some head phone and see if the sound is clear there, if so then you know its most likely the speakers.

The speaker is starting to buzz during the low


It probably buzzes all the time, you just notice it when it is outputting little volume. Check the cables for loose connections or replace them with other cable as a test.

I recently purchased a 52 inch LCD. I have


This could be the speakers are vibrating onto the casing and need padding out more to prevent this.If this isnt the case, you may have a sticking coil on one of your speakers..When the sound distorts, remove one speaker in turn to see which one(s) are the offending unit(s) and replace. Is there a buzzing noise coming from the speakers especially in low volume? If so then you may have a faulty capacitor in your power supply producing hum on sound. Hope this helps :)
