You can try to fill that huge room volume with sound from a single pair of speakers--but this is no easy task on a budget. Still... the Energy suggestion is interesting, and a PSB tower model might work too.
But if your ears are used to refined sound, chances are it will be hard to find a pair which will be efficient (and large) enough, and which can at the same time satisfy any need you may have for detail, smoothness and the rest of the high end qualities.
In that case, another option, a viable one for music, is nearfield listening. A pair of monitors on stands won't fill the room, but if you can sit near them the effect can be very satisfying indeed.
