Kjmo,
The problem might not be the beaming at the top end of the tweeter's range.
The problem might be excess off-axis energy in the lower end of the tweeter's range, 3-4 kHz. This is typically where the ear is most sensitive, and most speakers have a very wide radiation pattern in this region.
Amphion comes to mind as a possibility, with their shallow-waveguide-loaded tweeter. That shallow waveguide will control the radiation pattern in the lower treble region. Other possibilities are coaxials, like KEF. In either event, instead of aiming the speakers at your ears toe them in severely, so that the axes criss-crosss in front of your listening position. This warms 'em up a bit and avoids a strong early sidewall reflection. You might even point them directly at one another.
You can e-mail me for some other suggestions if you want.
