control room:

should i make a large bass trap with about a 4" gap on one wall if i would not be able to do the same on the other side to keep it symmetrical, but instead maybe a corner trap

do corner traps need to be air tight

Live room:

i have the opposite wall of my control room which is roughly 10' high x 11' wide, the existing structure is actually a garage door that is 8' x 8' itself, with an open frame structure on the inside. currently i just have plywood leaning against the wall, but i am curios if it would be ideal to turn the whole wall into a huge base trap, possiple a panel trap, would this be succesful if done correct.

last question, kind of for ethain winer, but please comment on the idea whoever you are.

in regard to covering rock wool with fabric to make it atrractive and not messy, would painting the fabric possibly work?

Sure. Although symmetry is always important, that's more of a mid/high frequency issue. For bass trapping, the most important thing is to have enough of it, wherever you can fit it.

Not if they're made of fiberglass only.

This will be difficult to do because wood panel traps absorb over a range of only one octave or so. So to trap the entire range you'd need different wood thicknesses.

If the goal is to absorb low frequencies, then a layer of paint will not hurt anything. But it will reduce the absorption at mid and high frequencies.
