Speakers that disappear

I once listened to some speakers where i was surprised by their disappearing act - I don't remember the brand - I think they were stand mounted. I am currently looking for speakers - not too big - and was hoping for recommendations - I know other components matter too but I understand some speakers are noted for this trait and some don't. I listen mostly to classical and vocals, lighter pop - no hard rock (I assume the Beatles and 60's count as "light" :) )  Speakers I have
