Wall/Ceiling Mount Speakers

[R3P0]

I am looking for a good setup of speakers not to expensive that will sound decent in a 15x15 room. The Audio amp will do HD codecs, however the catch for the speakers is going to be on the front I want to mount the front left and rights around the TV on the wall, the center channel below the TV on the wall, the rears I would like to mount from either my ceiling through my attic, or maybe on stands behind my couch IDK yet. this is just a 2nd setup my primary on in my basement is already set, but if anyone has any good suggestions for sat type speakers for a living room im all ears.
