Greetings all,

I'm going to start experimenting with series crossovers. An internet search will yield lots of material on the subject, so I'm not going to try and duplicate any of it here. Suffice to say, one of the main theoretical advantages to a series crossover is the lack of degrading devices directly in the signal path, only the series connected voice coils. One of the heretical projects will be a straight forward series crossover for the Dahlquist DQ-10. I’m not so sure that I can rival Jon’s and Saul’s design, but I’ll be thrilled if it turns out. Did they start out the same way before all of the tweaks they incorporated when theory alone gave an insufficient result? I'll find out. Irving Fried too was a fanatical adherent of the series topology. Anyway, if you're interested, my pal Kelle created this Excel calculator so that you can get values for Zeta 1, 1.2, .707 and .5 for any frequency or impedance, just download and unzip. Looking forward to the feedback.
