Electrical smell from cab

[Pookus]

At rehearsal last night I got a really strong burning electrical smell from one of my cabs. I haven't had any problems before. This is a homemade cab with a 300w 8ohm 12" Celestion in it. I have recently ported the cab which has increased the bass response. The speaker cable looked a bit flimsy when I took the back off today so I have replaced it with some seriously heavy duty cable (same stuff I use to link my Ashdown gear with). Any ideas what could have caused the burning smell?

Could be the voice coil heating up the glue that holds it on the former. I've had that smell from time to time and it's been a bit scary but nothing's stopped working yet (says he, inviting disaster).


It'd have to be [i]really[/i] flimsy speaker cable to give off a burning smell. 300W into 8 ohms is only 6 amps.
