Surround Back on wall speaker options

Im looking to get a pair of on wall speakers to use as my surround backs in a 7.1 system. Im looking for something reasonable that would blend well with my current system. I dont want to get in wall speakers, I dont like being locked into one location

Any help would be great, Im just starting to look now, current setup listed below. I like the Infinity Quadrapoles that I have and something like these but smaller would be great. I like the Martin Logan on wall speakers but they are more then I want to spend on these

Thanks

On-wall speakers

Check out the Paradigm Monitor on-wall bookshelf speakers. They are probably your best bet for a tonal match with your other paradigms. The paradigm dipole speakers might also work well for surround backs. You could run them in bipole mode for the surround back location.
