Is the speaker placement for my back 2 speakers really bad? Will this work or should I change this?

I realize they are fairly high above the couch but I'm not sure what other options I have as I do not want stands

I'm just curious if by mounting them here will I even hear the 5.1?

I'm curious about this as well. My rear surrounds about that high, but placed a little further apart. They are pointing more inward and down a little.

While not optimal you should still be ok, biggest thing will be your speaker setup (distance and volume levels or better yet room correction if your receiver has it.
You may want to aim them down toward you more before doing your setup, or move your brackets to the other side of the beam/soffet and let the speakers hang below it, the extra 8" or so could really make a difference.
