There was no link to any picture in your mail so I cannot comment. I tried bypassing the passive crossover in the RM30's and used digital crosssovers using Tact amps. This still did not resolve the dip in the 250-750Hz region, even crossing the woofers at about 700Hz. As a test, I made up a rig to simulate the RM40 design using 4 ribbon panels per side and two Peerless 6.5" drivers crossed at 750Hz, and a different ribbone tweeter which worked better in terms of measurement at the listening position. I also used corner subs controlled by the Tact 2.2XP. This sounded pretty good. I then built my line arrays which I am much happier with.
