Surround Sound Speakers

OK I am grabbing up a Harmon Kardmon AVR 240 for Christmas. I am looking for a good 7.1 speaker set-up. I've found a couple I like, but I was curious if anyone has any personal expereince with the Infinity TSS 450's or the Harmon Kardmon HKTS 8 speaker systems? I've also heard a polk audio setup it's just too expensive to justify. Both of the systems above I will end up with a 7.1 Setup for somewhere around 450. I'm aiming for under 500. Any suggestions?

for that price range, look at the Athena line of speakers. do a search over at avsforum for some feedback. I have them in my dedicated theater room and really like them, especially for the money.

Anyone else want to chime in?
