Great work, as usual, Joppe! While watching your videos I was struck by how taut your membranes are. As I’m sure you know, with electrostatics, tension is necessary so the diaphragms aren’t pulled into the stators even with no signal. That's not a concern for your magnetically driven panels, so I think you could safely try lower tension. That would lower the resonance frequency and probably reduce its Q as well. You may recall from the discussions in the parallel universe at diyaudio that my planar magnetic mid/tweeter panels incorporate a compliant surround. I have found that unless the tension gets ridiculously low, the low tension has not caused any trouble, and it keeps the fundamental resonance well out of the target range. Perhaps you’ve got other reasons to keep the tension high, but I thought I’d toss in the suggestion.
Again, great work, and fun-to-view videos!
