Follow the link in my post from last January. There you will find an impedance plot that compares the A3 impedance curve of the new mixer with latest crossover to that of the High-Impedance crossover mod of several years ago. Also shown is the impedance of my original crossover modification described in the Tweaks section.
My Wolcotts drive the A3's with the new mixer with ease, which has a minimum impedance of 4.2 ohms. With the stock mixer and my original crossover mod, which had a minimum impedance of 3.3 ohms, these same amps were clipping severely on peaks.
