My two front speakers or just one cant really tell, but I am getting a humming or a high pitch like its rattels. I thought it was because it was sitting on a glass shelf and due to the bass it would do it but i have it sitting on the floor and i still does it. Does anyone have any pointers? I have a Time Warner HD box going optical though the box to the RCA Receiver.

Is it the speakers for sure, or is it something else around your speakers?

Go here and download sweep number 6.

http://binkster.net/extras.shtml

Burn that to a cd, or run it through an mp3 player, and see if you can tell where the rattle coming from. Is it the speakers or is it something else in the room? If it is the speakers, is it only at certain frequencies, or do they rattle across the spectrum? Do you get the hum even when there is no signal going to the speakers?

See if you can get a little more info and fill us in, and we might be able to get you pointed in the right direction.

And it's the speaker for sure? What model speaker do you have? Does it sound like the woofer is blown (is there any visible damage)?

Do this happens all the time??? ...Did you notice this noise before???

Like Marshall said, a little more information will help, can you post how is the system set up (eg: crossover frequency, speaker set to small or large, Does it happens all the time, etc.) ...I remember when I got my JBL Stadium, one woofer was making a noise with a certain frequency, there was no physical damage to woofer; good thing is that it was brand new so I got a replacement.

Do you still have warranty??? ...if you do, I call RCA to get a replacement :yes: (it seems is the same problem I got with my JBL, a defective woofer).

Try swaping the speaker from L to R or R to L and see if it does the same noise, :huh:.

I am using fiber optic and it seems like to does it on doby digital or the other setting but not on sterero or 3 speaker stereo.. Would that mean that I dont have something set right or is the fiber optic bad?

I don't think so because you use the same cable to feed the signal (dolby digital, stereo or 3 channel), Right??? :yes:

Optical/Coaxial are cleaner signal ...they don't pick up any interference.

Do you get that humming sound with all sources (Sat, TV, DVD, etc.) or just with some??? ...if is with Sat/OTA channels, it could be that the signal is not clear :huh:

So, if I'm understanding this, you are getting the rattling on all sources connected via digital (optical and co-ax), but not analog (red and white RCA plugs). Is this correct?
