Naturally.
This picture was taken in 2001. Long before I had this many 700B's. At this particular time in history; I used the PL700B wired in a parallel configuration resulting in what I believe was a 4-ohm load at the time for just the Low end. I ran a single 400 to each set of speakers for the highs. The Speakers are designed and built already in a bi-amped configuration. I use the external electronic xovers for the low and high frequencies to the amps and then there's an internal 2-way xover inside the speaker to further separate the mids and highs at the proper crossover points.
Today, I use the 700B's on the high end too, with the gains down as the high frequencies like you say; are less demanding. I had to replace the 400's as they weren't cutting the mustard on the lows and I don't like running them at low impedances resulting in a very hot amp. I learned that quickly after I built these things 20 years ago, so here I am today with that issue solved.
These days it's ALL PL700B's for everything. I do not own a single PL400. And won't. But I still have these speakers. This is what's represented in the CAD file. This project will just be duplicating MORE...........
