[tech] monitors making a duff noise.

one of my monitors makes what i can only decribe as a
plasticy vibration type noise, like as if a a strip of
medication in one of those push thru bubble packs was on top
of it. It only happens when its cranked up a bit and playin
tunes with big long bass lines. It sounds as if its coming
from the housing, not the speaker actually playing the
noise. Any one any ideas on what it mite be befor i go
through the hassle of returning it?

cheers.

My old desktop developed a problem like that soon after I
got it.It turned out to be a warning sticker that was
holding about three wires together had come loose after
getting hot then losing its stick.It landed on something
else inside and nestled there,vibrating everytime a certain
note was struck.The noise nearly drove me insane and I
started to use earphones so I couldnt hear it any more.Took
me a while to track it down too.
Maybe its something as silly as a tag?
Im assuming youve checked all the screws/security
fasteners?

yeah checked all screws and took amp offa back and had a
butchers inside, i was half cut and feeling clumsy and
decided i was more likely to really screw summit up if i
poked around too much, but now you suggest that i'll get it
apart and check for stickers/labels. cheers Atwood.

sounds like something is loose, if it has warranty send it
back and get it repaired, don't tamper with it because you
could void your warranty

Probably too obvious, but worth saying in case; try swapping
the speakers over.
Perhaps nearby objects or something are resonating? Swapping
speakers should cause the resonance to move with the duff
speaker unless it isn't the speaker itself. i.e. physically
swap their positions.

Also try swapping the amp outputs over in case one of amp
channels is pre-distorting the signal making it appear to be
a mechanical fault with the speaker, rather than an
electrical fault with the amp. If it is the speaker,
swapping wires over shouldn't cause the fault to jump from
one to the other.

Do what larn said. If its under warranty the act of going
inside and screwing with it is going to void it. You should
only bother to fix it yourself if the warranty has expired.
That goes for anything that is mid-high end.
