Looks good from here. I will have to try a project like that one day.
Very interesting.

2nd-3nd-4nd distortion. How low could this go with steep crossover ?.

Nano magnetic planar ribbon - YouTube

Playing fullrange. You can hear the dipole dip at the side.

Looks like you're having fun with these ribbons. How does it sound?

There is felt in on the sides and the yarn in the Middle of the magnets.
the ribbon is ligth magnetic from nano iron in the glue. I have a link to
the nano iron in the 0.6my ribbon tread. By the way the magnetic ribbon
was invented by Johnny Sorensen a danish reviewer some 25 years ago.
