Klipsch RF-82 vs. Polk RTi12 vs. Yahama NS-777? HELP!

[Schrute Farms]

I am probably going to buy an Onkyo 875 for my new Home Theater room (room is 14' wide x 23' long). The Onkyo claims 140 watts per channel @ 8 ohms, I believe.

I have to choose between the:

1. Klipsch RF-82s for $500 each shipped
2. PolkAudio RTi12s for $508 each shipped
3. Yamaha NS-777s for only $240 each shipped

My dilemma is based on price, plus the fact that I want to complete my 7.1 set up with speakers from the same manufacturer. The center channel speakers would be:

1. Klipsch RC-64 for $1000 shipped YIKES, but awesome speaker!
2. Polk CSi5
3. Yamaha NS-C444

I have listened to the Klipsch and the Polks, but I can't find a store that sells both of them, so I can't compare very easily. The speakers will be used in a dedicated HT room for movies, not music. I like bass, but not at the expense of clarity. I don't want bass for the sake of bass, especially since I will have a 10 or 12" dedicated sub.

Can ya'll give me some advice? Thanks!
