The Imperial 6 does have some deep bass but it is way down in level. Try them and see. If you are getting some bass boom then the cheapest, simplest way to fix it is with digital EQ. You could build bass traps but they need to be big (like the corner posts of a boxing ring) and dense. The little panels you see on the walls in some rooms will only absorb and scatter much higher frequency reflections and will do nothing to correct any bass modes. Unless the room is very bright and reflective it's my opinion that you don't need them. Killing those reflections completely can make the room too dead and actually reduce the size of the soundstage.
Or third alternative is building/buying resonators to cancel the modes but again a lot more hassle than using EQ. Although getting the EQ right isn't just plug and play either.
