New build theater door reconmentations

I'm building a room in my basement for a theater 13 wide x 22 long by 9 high as of now. I woukd like to add double doors to the 22 foot side but I'm not site what to use. I don't expect this to be totally sound proof and cost is a consideration. Any recommendations would be appreciated. Wife wants to use. Barn style.sliding door bc it won't take up much room and I like the look but I'm worried it will ruin my soundproofing efforts.
