Inexpensive wall mount speakers

I have existing wall mount (surface mount, not in wall) speakers in my home. I'm looking to replace them (drivers are old). Rarely used but want something with a smaller footprint and decent ambient sound. I'll need to get 6 speakers so want to go with something that is reasonably priced. I have 2 setups for standard listening so this is not where I want to put money -- any suggestions for something that's decent?
