Assuming you can't get rid of your wife anytime soon for whatever reason, the best solution may be some form of room EQ. Something like the DSpeaker anti-mode 2.0 would take care of the hump and probably some other issues, and I've seen them pop up used from time to time for 500-600 bucks.

I doubt a sub will help since you'll likely want to cross it over well below 100Hz, although a sub is still a good idea for the other significant benefits it can bring. The anti-mode 2.0 can help integrate that as well. Best of luck with this.
