When using a parallel notch filter, do you add the notch filter resistor to the woofer resistance, when calculating the woofer's inductor value?
No.
The notch filter resistor really only acts at the notch frequency, below the notch, the notch inductor and it's DCR dominate, above the notch, the capacitor dominates.
I doubt the notch inductor DCR will affect crossover inductor calculations much.
The sum of the DCR's of the crossover and notch inductor will raise Qes (and Qts) and require a change in box design, though.

Thanks for the reply
Sorry I wasnt clear. I was referring to only the resistor in the notch filter and not the dcr on the inductor in the notch filter. I think that resistor would be in series with the woofer, which would add the resistor value (4.6ohm .ei) with the woofer resistance (8 ohm). Now, do I calculate for 12.6 ohm or 8 ohms?

I understood you quite clearly. The answer is no. The rest of my reply is FYI-perhaps an unwelcome complication....

Your FYI was very welcomed. I didn’t understand it at first but I understand a little now. Well, I still don’t quite understand it but I can figure it out since I know the answer is definitely no
Thank you for answering my questions
