Yes you will have to connect a sub woofer to the sub or LFE out connection
of your receiver. This way the bass from your cd, dvd or whatever you are
outputting sound from will be routed through this connection. This where
Dolby gets the 5.1 designation. Two front speakers, one center speaker,
two rear surrounds and the sub woofer. In other words five speakers and
one sub. I'm not familiar with the ss5 you speak of but if it has all
these speaker connections it should work well for you. Depending on
speaker size and the power output of the receiver.
Good luck.
