What I see is a very hard, reflective room with very little in the way of absorbent materials. So you probably have lots of bass but too much of everything else for proper balance.
I would suggest putting in wide-range absorbent panels and/or traps. The former is probably less conspicuous and, perhaps, you can put some on the ceiling in between the beams. That would seem quite unobtrusive. One or two diffusive panels on the wall behind the speakers would also help.
