Ok, here is what I get for the 4343 / 4350 crossover card in the 5234A. The dip is with the 2235H and 2122H in phase and the hump is with the polarity on the 2122H reversed.Originally posted by boputnam
OK, a challenge for you, if you're in a goofy enough mood for it. You're the only one I know could get it done...
Can you show the two cases of, say, either the 4343 or 4345, in biamp mode with the LF and "others" both in phase and in opposite phase (polarity)?
I'm dang curious how much of the troublesome summing is obviated by having the LF and low-MF out of phase.
