Lighting up the cones!?!

[Mark_Bass]

Hi guys,

So a rather worrying and strange thing happened the other day;
I was at band rehearsal and was dicking around with a bit of slappin' & a poppin' and i was looking at my cab as i was getting my funk on then saw that when i popped the rims around my speaker cones lit up! I did it a couple of times just to check i wasn't going mad then stopped. As i play a SVT HLF410 the light was also could be seen through the ports too :-s
So i turned off the amp and checked to make sure there was nothing burning or melting around my head or from the cab.
I turned my head back on and checked i hadn't accidentally over cranked the master volume and then carried on playing, didn't notice it again that night and there was no change to the quality of my sound.
Is this something that i should be very worried about? i.e have i fried anything?

I play an Ampeg svt-4 (mono-bridged) through a Ampeg SVT-4HLF

It's the horn protection lighting up and nothing to worry about. Horn crossovers have a bulb in the circuit that lights up to take excessive power away from the horn and stop it from blowing is the simple answer.

dnt some of these cabs have lights in them to show your pushing them a bit hard? im pretty sure my 610hlf did? never saw them tho?

My old Eden nemesis combo had an aircraft navigation light in it apparently for this very purpose, to protect the tweeter. Never managed to get it to light though.

Means you are probably clipping something in the amp, which isn't ideal if you are after clean.
