Hi Ed,
I have a measuring setup now and after completing my latest two way I decided to measure the AR.Coms. What I noticed was a 10db dip at around 3000hz. Almost like a reversed polarity on the tweeter. I had these crossovers made by madisound. I will try and reverse the polarity later in the week when I get time but was wondering if you had designed them like this or maybe the crossover got wired wrong. Any help would be appreciated. Regards, Paul.
