Hi,everybody! Some time ago I listened a T115 cab by Epifani,and,among other good things,it struck me the incredible colour that the horn tweeter brings. I tried to find out what's happening by writing an email to Epifani,but no answer...surely,the guys have too much work to do instead of answering on such issues. I also saw that Bergantino (among others) cabs use the same trick,so my inquiry could refere to Bergies too. The question is:what kind of crossover do they use? 2nd order,3rd?!? Aside of that,does the woofer have some filter,or only the tweeter? And the last one:in every case,how are the drivers polarised regarding to the crossover,regarding the phase response? Thanks a lot!
