Reducing The Dip

[Jean Doe]

Just moved into a new room which although being much larger than my old one, is a cube. This means that due to my large desk im setting close to the center of the room and therefore have a nasty dip between around 60 and 180 hz. Some tones just completely cancel out. I got traps in all four corners which helped the low end A LOT everywhere in my room apart from the mixing position which still sounds rubbish. Anyone got any ideas on how i could improve this? Traps between ceiling and walls possibly?
Cheers

First, you need to get away from the center of the room. See this:

I got traps in all four corners

Most rooms have 12 corners, so Yes, adding more bass traps in wall-ceiling and even wall-floor corners will help a lot. After that, yet more bass traps on the rear wall help further.
