Hey everyone! I own a Gallien Krueger 410 RBH and a 115 RBH cab. Until now I have been using them with my GK 400RB head, i.e. in full-range mode only. In such configuration the tweeters in the cabs should be protected by some device in the crossover in the cabs, right? Can you please elaborate on that? Sorry, I´m not a technical type.... I am also considering an upgrade to a GK 700RB head, which has the biamp mode - and unless I´m wrong, in biamp mode the internal crossovers in the cabs are bypassed, right? So if really so, how are the tweeters protected against overload, in the biamp mode? Thank you very much in advance for your replies!
