Blown ribbons is not a problem with the 3.6. Now one must abide by the advice and guidelines given in the instruction manual, especially when shipping the speaker. Picking the right amplifier to go with the speaker is also important. You don't want something that clips all the time due to insufficient power or voltage output.
Also, forget about bypassing fuses, jumpers, and such as these modifications are not well founded contrary to popular mythology. The improvement, if any, is generally a slight increase in magnitude of the ribbon output which is often perceived as better resolution but, in fact is just an increase in magnitude. Fact is, the 3.6 has excellent resolution in it's stock form. Altering or modifying the crossover can possibly improve the overall sound to some degree but, one should approach this with caution as well. If you want to improve the crossover then my advice is to bi-amp with an active line level crossover. There is a German fellow name Schneider that makes an excellent unit. I can look up his website if desired.
