The room and speakers together are the most important component. The two interact and should be viewed as a system. Room gain can supplement the bass of a smaller speaker or make a big one too bloated. How the room reverberates can determine how bright/natural a speaker sounds.
You can't have speakers that are too good. The used market, internet direct sales, and DIY construction of projects by _good_ designers can all keep the price tag reasonable there. However, a sub + monitor setup will give you more placement options to work arround poor rooms.
After that, things to minimize your rooms' effects would be good. A Tact room correction system, parametric EQ for the bass, tapestry you can hang on the wall to kill high frequency reflections, etc.
