Stinky Sub - uh oh?

Quick question:

So I got some new speakers recently, and I was testing them out at high volumes with the Tron: Legacy soundtrack. After about 30 minutes I noticed a smell; what I would consider a burning electronics type of smell, coming from the sub. It's a Def Tech 10", about 10 years old. I've never really pushed the sub this hard before. The sub still works, but I unplugged it and want to make sure I don't damage it further (and that I don't burn my house down). Has anyone had this happen before? Do you think it just got too warm, burning off some dust? Or is the amp about to blow?

Do you think it's safe to keep using at normal volumes?

Thanks,

Likely just heating up the voice coil some. You stopped, which was the right thing to do. The Tron movie killed one of my Jamo d7 ultra subs too, hopefully yours is fine.

Tron has beefy bass in it.

You could have been clipping the amp which causes extra heat build up in both the amp and woofer. Time for a beefier subwoofer...

I'm assuming this is a Prosub 1000 you were using which at best can only go down to about 37Hz before it drops like a rock. A movie live Tron has some very deep bass and I'm positive that Prosub just can't handle frequencies that low. The Prosub is best as a mid bass module and pretty much nothing more. I'd invest in a better sub. Trust me I own two Prosubs both being used as mid bass subs only.

Thanks guys. I smelled something funny and panicked a bit.

These things have fuses and built-in amps, I figured there would be some kind of safety measure in place that would prevent the amp from frying its own speaker. I'll be more careful. And I am hoping to upgrade subs when the wallet allows.

Is there a way to tell when it starts clipping?
