You don't have to be between the speakers to get correct timbre and a soundstage; it stays put no matter when you stand. They are very room filling. The entire bedroom would be the sweet spot.
Although the Mirage's (recommended by Johnnyb53) may be okay. I'm a tad concerned about sound quality from a dipole speaker though.
I can vouch for their sensitivity, too. I have one model up, the OMD-15, rated at 91dB. They are in a large, high ceiling open architecture living area, and 85 wpc is plenty even for bombastic symphonic music. 30 watts powering 93db sensitive loudspeakers in a bedroom should be plenty.
