I've heard good things about the Trentes, but as you say, the larger room probably needs floorstanders. In fact my current speakers are B&W 804's (matrix) which I never thought had a problem with room filling sound, but in their current placement they can sound a bit strained. Even with my excellent Cary 200WPC amp.
Its a large room, 20X35, with the speakers oriented to project through the 35' space. Not optimal, but the only way I could rig it with the projector.
