Nice work Sebastian, StigErik has a lot to answer for
My speakers don't look anything I imagined they would thanks to his influence. His are definitely a benchmark for OB.
Did you try crossing them over lower say somewhere around 150Hz?

What does it take to get a 7 or 8 incher to get to 80hz? IE what baffle size? How much EQ?
How loud do you want them to get?

95db.

I'm trying to understand the science behind baffle size and low frequency.

In othr words can you plaese tell how the baffle relates to low frequency.

First that stain color is amazing.

Here are the sensitivity and linearity measurements done at 2,83V from the listening spot, ~2,5m away from the speakers. Both are done completely without eq, including no 6dB/oct dipole compensation, there is just LR4 low pass at 800Hz.
