Before you go nuts and sell your speakers make sure they are set up properly. Make sure that they are square (use a bubble level). When they are square, put a laser pen on the top and swing the red laser dot on to the far wall. Put a post-it note on the far wall, and put a dot where the laser dot shines. Do the same thing to the other speaker, and make sure the laser falls directly on the dot which is on the post it, on the wall. If the laser on one of the speakers shines too low, shim, or adjust the speaker so that the laser dot is exactly on the pencil dot. Once you do this, the speaker will speak to you in sync. This will give you the best possible stereo image. Most floors are not level. Bi-wireing is good, and experiment with toe in and in some cases toe out. You will be amazed at how the sound will improve.
