So, there is an old saying dating back to the dawn of the solid-state era which states "Transistors make great fuse protectors." The idea being, of course, that of the two, transistors of the day were the weak link, not the fuse as intended.
I can testify from painful experience that "Infinity EMIT tweeters make great fuse protectors." I have a pair of Infinity Qb speakers, which I bought in 1979 and still adore, that use the EMIT. The EMIT is their best feature, in fact, but combined with the relatively low efficiency of the Qb and my taste in loud music, I have often driven amps into clipping and fried tweeters. The 1 1/4 Amp fast-blow fuses protect the tweeters maybe half to a third of the time. Going down to a 1 Amp fuse doesn't help and may in fact hurt for reasons I don't understand.
What I'm wondering is if the intervening 42 (FORTY-TWO) years has brought any advance in fuse technology that might resolve this ongoing problem. It would be nice to have a drop-in solution, but if I need to solder something in, I do have an Associates in Electronics, so I have the chops and the equipment to do that.
I recently got my hands on a pair of identical PA amps with good specs that, strapped in mono, provide something above 1000 WPC into my speakers, so clipping per-se is unlikely, but I still want to solve the underlying problem because I now have the power (MWUHAHAHAHA!) to destroy drivers even if I'm only feeding them clean waveforms.
Thanks for your help and suggestions,
