a ? for Thomas Barefoot

Hi Thomas and everyone else,
I have a pair of triamped Gennies, and a couple of days ago I noticed a bit of a rattle on one of the mid drivers. This rattling happens only on certain songs where some mid freq. sounds really stand out. For instance, I was listening to this piece that has only nylon guitar in it, and it's really noticable there. If I lightly put my finger on the edge of the cone, the rattling stops, but of course this changes the sound a bit too. Do you think this is a serious issue or is it an easy fix. I still haven't opened the speaker up. Should I and what should I look for? I'm not really good with the speaker electronics, but I can hear when something's wrong ...so if you can suggest something, please do.
Thank you very much

cheers

If the screws holding the speakers are tight, than take it to a repair shop, sounds like the speaker is bad. Then again, I'm not really good at speaker electronics, either.

Thanks Grinder,
I'm a happy man..I've fixed it about half hour after I posted the question. One of the thin mdf sort of "plates" that sits just behind the ports of the monitors was lose. (when I opened it up it was actually laying flat. I glued that back on calked around it with silicone and bingoo...that was my rattling there...Gee, what a relief... ..I thought it wouldn't be anything bad, coz I would probably hear it blow if it really had gone bad.
I took the whole driver apart anyway while the box was open just to make sure everyhting is OK, and all looks fine..
Thanks again for input

cheers

Hey Sen, I'm glad you fixed your problem!

Makes sense that something was mechanically loose. A blown driver will typically rattle across most of its frequency range. A alown active circuit component can cause buzzing at specific frequencies, but it’s more of an electronic square wave type buzz rather than a rattle.

Cool!

Thomas
