Digital Room Correction For Speakers

This has not been mentioned here, but in my experience, using dipole speakers (especially dipole bass) is a very effective way of reducing room interaction to start with (as in LXmini / LX521 speakers).

i have owned and used DIRAC mini dap and DEQX HDP-4

the DIRAC was easy to use and pretty good results by I expect you could achieve  very similar results with the Roon EQ and using your ears.

DEQX speaker correction was a clear win however you need a lot of patience and and hard work to fully understand and implement the rest of it effectively. great if you like this type of project where you can experiment endlessly but perhaps also leaves you constantly wondering if you have achieved the best results or not!

for a bass issue (and where room treatment may not be pratical) i would use Roon EQ by ear, and experiment with speaker placement.

I agree with soix recommendations. I thought of changing speakers myself after trying room treatments that did little to correct my bass problems. I also tried putting the supplied port plugs in my speakers that helped a little but I did not like the overall sound with them in place.
The DSPeaker 2.0 Dual Core was a major improvement over everything else I tried.

I wouldnt mess with EQ. If you have room modes you can solve this by adding mass to the room. An example would be to get concrete forms and fill them with sand. Books or albums can also help. Find a room mode calculator to see where your problem areas lie and then fix it in a way that will not detract from your sound. 

Any room EQ can fix some problems but might degrade the sound on other areas because every component that implement equaliser manipulate the sound and harm the original recording .You should be very careful once you decide to buy room EQ it's better to check it in your system and in your room what is exactly its affect on the sound and if you like it or not.
