@golden210,Your new room is not small. I would call it medium. I am in a similar situation as you are - room in the basement with 2 solid concrete walls and 2, 2X4
walls
with double drywall (on each side) glued together with Green Glue acoustic compound. This minimizes the sound leaks. I use GIK treatments in my room. The A2 seems front ported, which should be fine in that space you have. The tri-traps in the corners will help tame the bass.
Good luck.
