Polk speaker combinations

[heavyg]

I have a pair of Polk R1 speakers and a PSW100 Powered Subwoofer that I got from different sources.

I am wondeing if I could put together a decent Surrond system by adding other Polk products. Any advice on which Center and other speakers would combine with what I already have to make a nice Surround system would be appreciated.

Thanks, Gary
