As Hopat21 says --- Vandersteen makes pretty warm sounding speakers --- all across the spectrum of their line. I own some lower end Vandersteens (in a secondary system) and they are warm sounding.
That said, every one of the speakers listed by those posting answers to your questions --- every one of them (Vandersteens included) can be made to sound bright and/or harsh (read not lush/smooth/fatigue-free) if the electronics feeding them are provide the speakers a harsh/strident signal.
So... again, if you want a system that sounds full/rich and not bright, or thin, or strident --- then every component in the system (speakers and electronics) need to assesses for their contribution to the overall sound.
A "lush" sounding speaker will convey bright/non-lush sound if fed such a signal.
