Easy solution, just never sell the 3.7s! ;)
Very interesting setup! I can sort of imagine the effect you're getting is almost like listening through a set of headphones, in that sitting close and having no toe-in, you basically cancel out most of each speaker's sound from reaching your opposite ear. I actually have my 3.5s pretty wide with just a bit of toe-in and frequently find myself rolling my chair forward till I'm just a few feet behind them.. totally enveloping soundstage- an immersive musical experience. I can only imaging, with their coaxial drivers the 3.7 will take this experience to a different level.
Curious.. how big is your room and how far apart do you have the speakers?
