Vandersteeen 2wq (or any sub) in small room

Hi everyone,

I have an 11x16x8 room for music, with Vandersteen 2ce's and Aragon 8008BB amp. Tried all manner of placement, but still feel the bass is a bit thin (I realize that Vandersteens produce musical and accurate bass, but this is my perception). I have been reading about the merits of the 2wq sub in improving the Vandersteen sound, but these advocates usually have much larger rooms. Is using a sub in a small room a fool's errand? Would teh 2wq be a particularly finicky addition? Should I return to my efforts at room treatment with bass traps? Thank you. 

Paul.
