I tested the tweeter of my schro 1210 and for the tone I like it didnt seem to make much of a difference. I play classic rock and like the vintage type tone. Are tweeters for people who slap and like a lot of highs? I checked out a few of the cabs at our rehearsal studio including an Ampeg 2x15, peavey 4x12 and gk 4x10. None had tweeters and they all sound fine to me. I am going to buy a neo 1210 from Jorg and I need to decide if I should spend the extra $120US on the tweeter or not. Am I missing something?
