When i'm setting up speakers and they're bright or have that glare in the midrange I pull them away from the first reflection point. In my tv room I'll pull the in front of the monitor a little more than usual and if I can't get them away from the sidewall enough I use more extreme toe in. Looking at response curves for bright speakers, not necessarily B&W, jagged measurements evan fairly slight can cause trouble in the wrong room so maybe some digital room correction software? good luck
