I think you may have a hard time improving on the Legacy Monitors with a sub 1000/750 wall mount but good luck with it.
Here is my rec. I bought a pair of NHT SuperOnes for <300. My criteria for choosing them were: Had to be wall mounts, white, soft dome tweeter, sealed cabinet with 6" woofer, actually came with their own wall mount brackets, and an easy load (8 nominal/6 minimum).
These were for a guest bedroom with some vintage Marantz receivers. I have a wonderful wife who says nothing about my other 2 systems with 6' tall speakers, so I didn't want to push it.
Works for me.
