Yep. Desks and consoles usually cause a bump at around 100hz. But it's almost a neccesity in mixing rooms. Please, post new measurements which are useable.
You can reduce it, by placing speakers behind and further away from the desk. If you have desk close to the speakers and angle it to reduce high frequency ER, it still usually causes that low / lowmid freq bump and nastiness.

Alright gents, this is an update.
As you know, I got rid of my desk and that eliminated the 120HZ peak.
However, I was still having problems with that 68HZ null, that kept moving slightly up and down based on speaker positon. I just couldn't eliminate it. I then decided to remove my Focal Shapes which are Side Firing passive radiator Monitors and borrowed a friend's Genelec 8030 Rear Ported speakers. All of a sudden, the room sounded alive, every frequency was clear. The difference was night and day.
It looks like the whole time, the Focal Monitors were the reason for this big null.
Now I have no choice but to sell these monitors. The question is, what do I replace them with?
1. Rear ported Genelec's - where i will still have to move the speakers around to help with SBIR? 2. Front ported speakers like Adam A7X's - where apparently since they are front ported, the issue of SBIR gets eliminated? Is this true?
Would appreciate any advise!

I have no idea but this is an interesting turn of events.

That's a perfect example why you should always try monitors in your room. Take for example 2 or 3 professionally designed rooms(even by same designer), and still one pair of speakers sounds different in every of those rooms.
That is why, most of the time there are already decided what speaker the engineer will use in the room, even before its built.
Answer to your questions 1 & 2: It's impossible to say like that. SBIR is there with every speaker, if its put on an enclosed space. But I can recommend one good speaker that works pretty well in different rooms; Neumann KH310. Its sealed design, helps a tad.
Focals tend to be really picky about placement, at least twin 6be. Suspect the same for the shape twin.
Room acoustics are really pain in the ass, without good design. All things affect everything, and everything affects to all things. That's why measurements are vital, especially if you're a beginner and don't have tons of experience from hundreds of rooms...

That’s very valuable feedback. Thanks Pasim. I’m def going to check out those Neumanns. At least I know that small Genelecs work in the room for the moment.
The problem with South Africa unfortunately is that we have very little suppliers on the ground here and they definitely do not allow people to do home demos due to the crazy crime and theft in the country. A bit of a scary country.
I’m going to have to take a punt! Appreciate your help as always

I live in a safe place, but its same for me, really hard to get my hands on to demo speakers. Basically have to buy before I can try...

Do the Neumann KH120 also have this advantage of being a sealed design? I think they are more in my price range.

They were little more forgiving to placement, better directivity and smaller size than my Focal Twin6's, so little less early reflections at HF. But I never used them in the studio actually, just tried em there. I had the "small speaker" problem with them, it just felt that you couldn't really monitor with them. They are great speaker, really neutral. But they have only one 5" woofer... Cant break the laws of physics here.
