Recommended room correction EQ settings for Elac DBR62?

[olds1959special]

I am new to REW, but exported the highest res image I could figure out how to do with the free version. Can someone recommend room correction EQ settings for me using AUNBandEQ? Measured using Behringer ECM8000 mic with Focusrite ISA One (medium impedance) into Apogee Duet 3. Thanks!

I mostly just need to know what width to use. I'm making a notch filter at 124.48 Hz , -5.0 dB. 0.3 Width seems like the sweet spot but I'm not sure.
