Best small, wall-mountable speakers?

Looking to wall mount rear channel speakers for the HT. Problem is it's an old house not favorable to today's audio demands. One speaker will have to be in the entry way of room at about head high. Currently have set of older Paradigm Atoms and some Target wall mount brackets. Asking suggestions for even smaller speakers that can be swivel bracket mounted. Would also hope to improve on the Atoms sound. Any ideas will be greatly appreciated. Thanks, Dave
Maybe not the "best," but the Gallo line would be worth your consideration
