CSi3 buzzing...

xandra

Yesterday, as I was really close to the speaker, I noticed my CSi3 was making a buzzing? rattling-like? sound when playing really low tones. I hadn't noticed this before - but the speaker has never sounded great to me - and the buzzing isn't audible at a distance.

I took off the 'cover' and put my ear up to each driver and still couldn't tell where it was coming from... but it's definitely coming from the speaker itself.

What could be causing this? Any ideas? As I said, it only occurs during very bass sounds.

You may not be able to do this but the best way to isolate you noise is to run test tones. The website below will have the tones you need.

You first run the 20 to 60HZ sine sweep to see if the noise occurs. If not go to the 20 to 120 HZ sine sweep. Once the buzz is found use the specific

Sorry clicked the wrong button!
Anyway, if you can find the specific frequency that makes this problem go into resonance it should light it up like a Christmas tree so to speak and you should be able to isolate where the problem lies. Most time you can figure out from there is it something like a loose screw or any other easily fixable problem.

I hope this help,

VERY IMPORTANT!!! RUN THESE SWEPT SINE TESTS AT A VERY LOW VOLUME!

I should have mentioned that right away!

jbay, thanks for the advice (link a great resource too) I'll give it a try as soon as I can get my dog out of the house - (she goes positively beserk with test tones).
