I've installed both but have never compared them side by side. If you have side walls you might like the FS7 better as it tries to bounce sound off the walls. So if your room is open to other areas on the sides it won't give as good effect. It has been a longtime since I have seen one of these but from memory I would take the FS7 over the SSA-50 if I had side walls. The SSA-50 creates it soundstage by adjusting the phase between drivers which gives a nice wide sound stage but is not as natural sounding but will work better in open areas.
