I also think MBL 101 would work great. They will surely also get a lot of comments for their looks, people will notice them. See if you can find a used pair.
Other than that I think the Kii Three with bass towers could fill a room. The include amps, you only have to add a streamer.
Third option would be horns, they can fill a room with sound. Used to be used in theaters. Used Acapella should work but might be expensive.
