polk series II used in 7.1 system (1 Viewer)

[rexbd]

Hope this isn't stupid. I have just bought a new amp a Denon AVR 1912. I have Polk Series II speakers. I don't have the money for new speakers right now but saw on Ebay I can pick up the same speakers for next to nothing and was wondering if I could add two matching satellites and go with a 7 speaker system. I will eventually get some newer speakers but not in the cards right now.

Should be fine. In fact using all matching speakers should be a great idea.
