HELP Building bass traps & panels with room calculations-Acoustics Forum-Acoustic Fields Forum

I have a 8’8″ x 12’4″ x 6’8″ room.

I have recently made calculations on REW, here are the graphs.

I recognize is the dip at 110HZ could be from SBIR and so I do plan on adjusting my monitors. Currently I have them two feet off the wall with no specific measurements. I have learned that since I have a room on the small side I could put my monitors close to the wall with absorbers right behind since I can’t flush mount my speakers.

What I am onto next is constructing panels and bass absorbers (since I am on a slight budget). What I would love to know is how thick I should construct these and where would the ideal place to place them be. I am attempting to create my room as a production/mixing room. I also want to figure out how to set up a mic spot for the best vocal production (I was thinking of being able to move panels if need be to give the vocals more roomier sound)

Would appreciate all the help y’all can offer. :D
