OK my assumption that your listening position was further from the speakers than the speakers are from each other makes my suggestion a bit obtuse. Lets see if this will work, rotate your speaker(s) until the axis is approximately 18 to 20 degrees past your head position. Listen for a while to the new sound (I would do it for some days - just getting used to hearing it). Then then start rotating the speakers back towards your head until the sound improves or deteriorates. When it deteriorates stop and go back the other way by say 50%. And so forth. You should find a sweet spot some where in the range.
Also, since the rear of your speaker is now likely pointed at the side wall/corner behind the speaker, you could temporarily hang a heavy blanket on the wall to see if deadening some the speaker's back tweeter will be beneficial to you. Or if that is not possible, you might try hanging a blanket or two on the wall behind the speakers helps at all. This is all trial and error stuff but if you find a real improvement you can always find domestic materials from bookcases with books, drapes, plants etc which will serve nearly as well as high end and ugly acoustic materials.
This is a slow process but can really be worthwhile.
