You would have to add L-pad attenuators on tweeter and midrange. But it would also mess up the woofer to midrange crossover a bit.

Would be better to just use bass control dial on your amp if it has one.

overall I am satisfied with the bass performance
but i would like to give the woofer a little boost ( more power ) for greater bass response .

Do you mean a circuit like this ?
the LPF has a 1.8mH which resistor should I place (Rbsc)

Could you add a passive radiator on the back or try to make a custom grill made from wood with just a slot that 3in wide by 7 to 9 in long to load the woofer I tried it on my woofer box which is also a three way and I get more bass output the grill should be about 3in above the woofer to clear xmax
