Controllroom plans

Hi, this is my first post here! My name is Marius, I work as a recording technician and mixer in a studio in Trondheim, Norway. I turn to this forum for guidance in my process of treating the controllroom in the studio. Room dimensions(LxWxH): 20feetx10feetx7,5feet The construction is solid, with floating floor and well isolated walls(mass,air mass). The construction can not be altered. Loudness is not a problem, because of the design of walls/floor. Goals for this process: I would like to make the controllroom the best it can be by treating it acousticaly with bass/broadband traps, and finding the optimal listening and speaker placement position. I know the room-dimensions are far from optimal, but I choose to view it as a challenge. To start of, attached is a SketchUP illustration of my plans before any input from the knowlegable people on this forum. After reading many threads in this great forum, I have calculated the problematic frequenzies in my room, and come to the conclusion that: I have a problem haha :shot: The meassurements I have taken with sinewave sweeps confirm these frequencies, and walking around in the room, I can spot the nulls and peaks. Listening/speaker position: The current listeningposition is at 10feet from back/front wall, and the monitors are placed to form a triangle with side of aprox. 5feet. Am I correct in thinking that the optimal spot for listening/monitorplacement can be found like I have atempted in the second picture attached? Dark green squares are my planned positions. (picked up this technique from someone on the forum) Treatment: Will treating the corners with superchunks and building a large basstrap(4feet deep) in one end of the room like in the picture above plus adding a cloud and first reflection broadband absorbers be sufficient? So, what say you? Am I far of the mark with my plans? Budget is max 500$, but I have 2-3 qubic meters of rockwool to use for acoustic traps. Thank you, Marius

as a general rule, 38% from the front to start and then adjusting the monitors and seating until a best possible response is measured/observed. if you're not going with soffits etc then superchunks in the corners and wall-ceiling. clouds are good and can be angled. using multiple clouds makes a variety of adjustments possible but sometimes a massive cloud is needed but in this small room probably better to go with several. here's one idea on layout.
