how to treat subs behind screen wall

What should I pack my little area behind my screen wall where I'm placing my subs? More pink fluffy, build base traps with 703, linacoustic?

Thick pink fluffy is a bass absorber.

any cavity needs something that one looks nasty and would be prone to resonances, I would fill it up.

Since bags of sand are probably cheaper at $3-4 per bag or so, how many would I need? Just a few 50 lbs? I don't I would need to fill the whole cavity with bags, right?

fill the same area you were planning on filling with pink fluffy, Your goal is to eliminate open cavities that can resonate one way or another. You and your back can probably appreciate the choice of pink fluffy.
