Assuming the screen is on short wall (10 feet), FS may be a hit or miss.
Towers need space around them. Min 2-3 feet away from walls, depending on design and bass extension. If you tuck them into a corner, they will misbehave.
Since you are looking at a HT/music setup, give stand-mounts or smaller form factor speakers a listen. For bass effects in movies, sub will do the duty.
Don't put yourself in a position of buying FS and then struggling with placement.
Invest in a good center channel for movies.
