The resistors I use typically vary between 1/4W and 20W. It is OK to use a resistor with a higher power rating than you need. It can be useful to have a stock of 5W resistors of different values to use. When you use them on a woofer, it is best to play music through them then feel them. If you cannot keep your finger on them then you need to be using a higher rated part.

If your tweeter impedance is smooth enough to work with then you don't need the parallel resistor.
Thank you sir! I will continue the calculations. Best.
