Don't listen to offki, what you need to do is knock a couple of walls down. Then rebuild them at an angle. Ditto ceiling. :-) What you need is spectrum analysis.
Small rooms are deprecated; besides which, they won't support an extended bass response. (Saves on a sub-woofer?). In a small room the fundamental resonant modes are more likely to fall awkwardly closer together in frequency than in a large room. This could make trapping them simpler (e.g. one trap may serve two modes) - or not - but you need an accurate acoustic picture before you start working on them. Also with a small room, expect at least one pug ugly flutter echo somewhere in the midband.
