Yes, digital correction can be helpful, and Audssey focuses on more than merely the freq domain.
But..... EQ'ing above the transition frequency is a minefield at best, and typically acoustics experts/studio designers would likely say it's impossible,...especially for a multiple person space.
Now an outdoor system, for one LP, go for it. Indoor, acoustics types would say you're trying to fix an acoustic problem electronically. For example, a measurement mic @ the LP measures the power response, however when frequency EQ is applied so the measured response @ the LP is flat, perhaps the axial direct sound will now not be flat. So you've created another issue by attempting to solve the first.
Many FR fluctuations are caused by destructive interaction of both the direct and reflected energy off the boundaries. So upon attempting to flatten the fluctuations, typically it may not work because an increase in the direct energy is met by a similar increase in reflected energy. Some flattening can be achieved, but like I said, solving an acoustics issue with electronic signal shaping is a minefield.
Addressing SBIR with either; a.) flush mounted mains, or b.) significant absorption around the mains end of the room, then a surgical smattering of early reflection treatments (diffuse or absorption), and a good acoustically dead ceiling area between the mains and the listener,...then a decently scattered/diffuse remainder of the room with no large surfaces left untreated in some fashion,... all that should serve you well. You mate that with mains with tonal characteristics that are relatively neutral/flat, you may not need to EQ above the transition frequency.
Below the transition, EQ till the cows come home .
