Bass traps in the corners of the room can do quite a bit to even out bass response. Even when you go to a bigger room, tube traps will be a help. Treat at least one end of the room (traps in each corner) and preferrably all four.
To with the biggest traps you can get away with--there is no substitute for thickness/mass when it comes to bass trapping (the exception would be "active" bass traps which use a speaker that cancels bass). With the round bass traps, like the ASC tube traps, I like the 16" models.
