Whats the point in putting a Quick Blow Glass Fuse on the cross over network of a mid/high speaker when it can not prevent the Compression Diaphragm from shorting out !

they are fuses weather they can be used as a light bulb or not, it performs the same function, as well as very basic limiting. Stop nit picking. fuse
clearly they were not the correct rating. |

Not a bulb. People in the know call them lamps!

Whenever I'm in the wholesalers and a member of the public comes in asking for bulbs, one guy behind the counter always says that. Every bloody time.

I think it's an age thing. I call those bulbs and I call decorative table fixtures 'lamps' as in 'standard lamp' or 'bedside lamp'.
But this is well-trodden nonsense. Those limiter lamps are meant to afford limiting. If they blow, you've ridden the limiter once too often. Some manufacturers use fuses, some use bulbs, some use PTC thermistors (polyswitches), some use thermal breakers and some use sweet FA. I don't think they're designed to be fool proof, which is ironic in a way. Yes, I have customers who think they have novel sound-to-light loudspeakers that are actually meant to flash to the bass beat as an attractive feature of their speakers. Honestly. |

Agreed - by the time there is enough voltage to blow the lamp / bulb / illumination device, it has well and truly gone past its limiting capability. By the look of the shattered diaphragms. these boxes have been pushed way past what they were designed to do - simple abuse..... Edited by Centauri - 07 December 2011 at 11:29pm |
