I use even smaller Harbeth P3ESR speakers as desktop speakers in my study. Due to the proximity of the desktop surface, even with the speakers on small desktop stands, I suspected a bass hump. And indeed, measuring with REW, I found some peaks. I downloaded an equalization curve into the Equalizer APO/Peace software on the desktop computer that I use as a source, and this resulted in a meaningfully cleaner sound. So I do think it is worthwhile. If you do not use a computer as a source, a MiniDSP is a cheap way to implement REW equalization.
I don't know your room (or your wife), but your speakers do not extend very far down. Unless your room is very small, I would think that a pair of small subwoofers like the black gloss SVS SB1000 (or even smaller, the REL T zero) could be hidden in two corners of the room. They would extend the frequency response significantly (particularly the SB1000s), and combined with a DSpeaker Antimode 8033 room eq unit give a very smooth response.
