Surrounds aren't really rears, they're more sides. You get rear surrounds with 7.1, tho. This for movies and music? For movies I wouldn't worry about the surrounds so much, altho for multich music having the same speaker all around can be nice. What sort of size limit? Budget? NHTs could be one way to go, but there are many ways you can go for a wall-mounted speaker....a sealed speaker or front ported might be best for a wall mount, tho.
