As for "not getting great sound" in a room like that...
Some of the best sound I've ever heard were large speakers in small rooms. (That includes mine, but I've heard higher end speakers in other small rooms).  Often a small room means the speakers end up closer to nearfield, taking out some of the room.  That's also how I listen to my floor standing speakers and they usually sound much better than demos even in larger, dedicated high end audio store rooms.Â
Of course not every large speaker will work in every small room. But, so long as we aren't talking about someone placing speakers haphazardly in a reflective tile bathroom or something, someone who knows what he is doing can render terrific results in atypical rooms.
