So, it's not 'ripping' out a driver'... it's just replacing one :)
No tone control, diff room placement not feasible (besides, that in all likelihood wouldn't help what I am looking to cure), and I do not have an EQ. Trying to not get one; trying to keep the signal as pure and clean as possible. I would buy new speakers before adding an EQ. Which to some is going to seem counter productive, I know, but...
Why would I need a redesigned crossover if i swap a woofer?
