Are you going to keep those NHT Superzero speakers?
I have a pair of Superzeros I bought 20 years ago for use as rear channels in my 5.1 system. They were good with my old JBL L100s, worked quite well with my original SongTowers, and I still use them today with my Veracity STs. Their overall neutral balance goes well with Jim Salk & Dennis Murphy's sense of neutral balance. They're small and easy to mount on walls.
