If you want to get technical about it, a bunch of very small ferrite beads, teeny tiny ferrites, located around the room, primarily along the 90 degree angles where walls meet walls and where walls meet the ceiling, every coupla feet, does wonders for the sound. Been there, done that. Thimk outside the box.
