Hi cw, (long time no chat)
The best speakers i have heard in a REALLY big room are Avantgarde Trios/Basshorns and the new MetaPrimos (preferred the Trios/BHs to MPs - bass on an array of BHs is magnificent). I love the way large horns can "project." To do it more cheaply, one might get away with Oris horns with LaScala-type bass cabinets and if one were sitting close enough, they would do very well. Another possibility might be something like Edgarhorns with his Seismic subs or even the set-up on sogood51's link. Cheers!
