what would make my speakers smell?

[Cal Weldon]

Sorry to hear.

Thats real bad luck when something like that happens.

Only drive units directly connected to the amp (DC wise) would suffer. So any mid or hf drivers that are cap coupled will be 100% untouched.

Don't know if you want to hear this or not. You've asked though...

There's just no practical way to know if they have suffered or not short of testing them in a lab. The first things to happen is for glue to soften as the coil heats, real excess heat will burn the voice coil insulation (shorted turns eventually, open circuit after that, or just fail open).

The mind plays tricks... I can well believe you might think it's not as it was when in reality nothing has changed.

I think you probably got away with it

Place matching speakers face to face about an inch apart. Wire them both to the same channel with one out of phase with the other. If you hear more lows than anything else... bad woofer, more mids... bad mid... more tweets... too many twitter friends.

Thanks for good words.

They are DC coupled, MKT caps. But they cooked a bit, at least.
Right now they do music, I'll try the wave cancellation tip Simon.
