The most holographic speakers i have heard in my life are the Omega SAM's they put a huge sound scape that envelopes you in the listening space. I've yet to find a speaker that can do what they did for sound staging. They have other issues though and do need subs to flesh out the bottom end and in the wrong set up can sound a bit shouty. but properly set up they win the holographic sound stage award.
second would be the smaller stand mount BBC monitor types like the Proac Tablets, LS's etc. again need bass reinforcement. and wont rock out well.
