Roger-
Since my mids were recently rebuilt at the factory, I'm planning on another approach (that doesn't require replacing or re-wiring the mylar) to move the magnet/perforated panel closer to the mylar (and closer to flat). This weekend I'll be testing to see if adding cross bars at 2 or 3 locations to the rear of the panel, pushing it closer to flat (but not quite there, per Magnepan). If that raises the output level, I'll route out some grooves in the MDF panel to mount the bars, which will also help hold the panel in place.
I'll post my progress.
Thanks,
Mike
