I'm suggesting that short of doing frequency response measurements, then rather than just making it smaller, experiment with different sizes to find the one that best mates [blends] the driver's forward output to its rear output without any obvious peak or dip in the lower mids response.
WRT = with regard to/with reference to
XO = crossover
BW = band-width

I did not chop my BIB baffles, just painted them red and recessed the drivers flush which surprisingly made a difference in sound.
I'm up for EnABLing now. I found patterns for different speakers but none for round baffles. Baffles are 34cm wide before the round off starts.
Thanks, Mack
If I've got the worse, then anything would be an improvement. I had a couple of wave guide blanks left over after building a pair of Bob Brines MTLTs. I found some spray paint on sale and went to work.

An externally hosted image should be here but it was not working when we last tested it.

The ellipses are rounded over from the driver outward. The FE166 drivers are less beamy - I don't have to sit in the middle of the sofa and cocking my head makes less of a difference.
There is much less of the occasional harshness that hurts my ears on a certain frequency.
I've got new speakers again. Thanks GM, thanks Bob.
Cheers, Mack
BTW, the white bits on the red sound wave concentrators is double sided tape that was used to hold up foam and carpet padding to try and tame the harshness. I couldn't hear that the padding made much difference. I couldn't get the tape off so decided it was just thick EnABLing : )
