Following up on what Narrod offered, a square room that size will make the bass response very uneven because there will be a large bass boost at some bass frequency. This will make the bass way out of true proportion whenever you hit notes in the boosted frequency band.
So trying for "full-range" in such a room could be a frustrating and futile experience. And the more powerful the speaker's bass response is, the more this uneven response will be exascerbated.
On the other hand, if you can calculate or measure the frequency of the bass hump, you may be able to find monitor speakers that roll-off before that point so that the big bump corresponds to the speaker's natural roll off.
Anyway, if you plan on going deep in the bass in that room you will probably need some judicious room equalization.
But just so we are on the same page, you do realize that most people can't actually hear a 20Hz tone but you can tell it's there because it will physically vibrate/shake the room and other objects within the room... There are almost no instruments that play down that low except for organ.
