“Sadly, I can’t say I’m surprised by all the suggestions to simply throw money at the problem with another large, ported bookshelf speaker. For crying out loud, the guy has his speakers within 10" (that’s inches btw) of the wall!“
I agree and suggested a week ago eq, digital correction, and/or room treatment, as have several others. The OP is unwilling to work with the obvious choices of moving the speakers out (which can be easily done for listening and moved back when done given their size) or otherwise maximizing what he has. Unless he purchases speakers specifically designed to be put against the wall, or close to it (Vortex Acoustics, some totems, nearfield studio monitors, custom) changing speakers will not fix the problem.
