Since I don't wanted to invest too much into acoustic treatment, I set up my monitors and the subwoofer the best way I could in my room, by measuring with a software called Room Equalizer Wizard (REW, freeware) and an omnidirectional mic. I then started to apply equalization to get at least my frequency response as flat as possible.
I know that doesn't help with reflections, delay time (not too much a problem here) and room modes, which are definitely a problem in my room too.
Now the setup sounds quite amazing, and is quite linear as well - I feel like mixing got way easier than ever before. Having a monitor setup that you can fully trust is essential for good mixing/mastering I'd say, and my mixes never sounded as good on other speakers before too.

Is there any major downside to doing room correction by this method? I know that the EQ changes are quite extreme so I'd love to hear your opinion on that.

Here's the correction that I applied:


Would love to hear your opinion on this!

I like that EQ curve. The regular dips make it look like your room's kind of comb filtering your sound, which I guess maybe makes sense if you've got echos coming off the walls?

Did you look into IK's ARC 2 (Advanced Room Correction)?

Yeah I have heard about it, seems very professional to me - I probably did what the program is doing by myself (only to a certain extend) as I measured at different spots in the room too and then used the average, and it seems to have worked quite well for me so I'm not willing to spend this much right now to see if it gets better. Would be interested to hear how satisfied you are though once you apply it!

I don't think that these are echo issues though, as I don't hear my hand clap being reflected multiple times from the walls (Like exactly hearing the clap multiple times bouncing back from the walls). The comb-look are most likely the room modes that I am treating: Probably at something like 33hz and the octave 66hz, 45hz, and so on... It gets way better in the midrange, as those wave lengths of the frequencies are way shorter and don't get so easily in/out of phase with each other.

IM NOT SURE , BUT PHASING MIGHT BE A PROBLEM I DONT REMEMBER WHY BUT I HEARD THAT EQ CHANGING THE PHASE

You're right, I haven't considered this. I'm thinking this might not matter too much since the room correction is happening to the "master" basically, and so therefore it does not matter?
In the mix eqing can definitely be a problem, especially when recording one sound source with multiple microphones and applying different eqs to individual tracks.

Appreciate your thoughts!
