How to do room acoustics correction the easy way.

To do it thoroghly It’s more complex than that ....  Room correction software is NOT your secret weapon.  Alas, you can’t simply apply digital room correction to fix your acoustics. 

Room EQ can tame some issues, but it can’t correct for long reverberation times or comb filtering caused by strong early reflections (like those nasty reflections produced by speaker boundary interference 

To tame these problems you have two weapons in your arsenal: smart room layout and acoustic treatment.

For the latter, start  by mounting bass absorbers and treating your first reflection points. Then ideally apply  treatment to the ceiling and all walls of your room if possible with modular acoustic control panels, / sound absorption acoustic panels . Expert applications with all their professional gizmos instead of a DIY cheap as you can go approach is worth considering
