Please Tell Me I Didn't Blow A Speaker...

Just the other day, I was listening to ELP in the living room at, shall we say, 'elevated' volume. Well, I forgot to check that the "B" speakers in the kitchen were switched off. They are in-ceiling, infinite baffle, i.e. I haven't constructed backer boxes for them yet. Of course, that arrangement makes them kinda vulnerable to overpowering.

Just yesterday, I noticed a slight, intermittant crackle coming from the mid/woofer in one of those speakers. It isn't loud, or constant and it doesn't seem to happen at any particular frequency. I removed it from the baffle and didn't see any visible damage. I am concerned that I did damage it though. I don't know what else would cause that strange crackling noise. It only comes from that one speaker, so it can't be a problem "upstream". Any suggestions?

It sounds like a cone voice coil separation to me.

One or the other.

1)Loose wire connection at the speaker or the amp.

2)Voice coil is toast.

Tell me Doc - is it terminal?
You need to remove the driver and run it via an oscillator at a range of frequencies, that will confirm damage or not quickly. If the speaker is damaged as I suspect, it will require reconing. You can do this if you can get the parts. Or you can send it for repair.

Seriously, I have no life.
TrueRTA is a free download that has an oscillator with several waveforms. It's easy to use, too. The freeware version cone with 1 octave resolution but upgrades can be purchased for 1/3, 1/6 and 1/12 octave resolution.

Get the freeware and use the oscillator, then decide.
