HT setup need XPA-2 or XPA-5?

[4311cixpa]

Setup:
Denon 4311ci: 7.1ch HT (140/channel 8ohms)
Polk RTi12 (Front): www.polkaudio.com/products/rti12
Polk CSi5 (Center): www.polkaudio.com/products/csi5
Klipsch S-3 (Surrounds): www.klipsch.com/s-3-surround-speaker
Klipsch RW-12 (2 Subs): www.klipsch.com/rw-12d-subwoofer

1. Will these speakers match HT setup?

2. Denon will run surround speakers OR + center speaker?
My Front (50-500 watts\channel) definitely need more.
Does my Center (20-200 watts\channel) need external amp or Denon
(140/channel) will run it fine?

3. XPA-5 unused power goes to the channels being used. Is this true?:
5 channels - 8 ohm = 200 watts per channel
4 channels - 8 ohm = 230 watts per channel
3 channels - 8 ohm = 250 watts per channel
2 channels - 8 ohm = 275 watts per channel
1 channel - 8 ohm = 300 watts per channel

XPA-2: 300 watts RMS/ channel into 8 ohms
1,000 watts RMS bridged

4. Should I get XPA-2 OR XPA-5 (if my center need power)?

Please help
Thanks.

Read this thread - the bottom two posts specifically. I'd recommend the XPA-2 or XPA-3 - depending on the answer to the question "What is more important - movies or music"?

If I get XPA-5, will unused power goes to the channels being used?
2 channels - 8 ohm = 275 watts per channel
3 channels - 8 ohm = 250 watts per channel
Thanks.

Get the XPA-5. I have one driving my L/C/R and 2 surrounds. Great product. Make room in your rack for this beast. ;D

Coach,
Have you try use XPA-5 run L/R only?
I want to know if the watts/per channel power different (higher) without Center speaker.
Thanks.

Yes. However, there is no firm figure on how much or maybe there is, Im not aware of it

XPA2 and 3 will be a good match for Rt12 especially for home theater. I have the same set up and I'm happy with it. You can add
XSP1 for music and you will be amassed it sounded like a different speakers.

Hi, I am a newbie in this site and planning to buy emotiva XPA3.
I currently have monitor audio RX6 as fronts and RX centre powered by onkyo tx-nr 708. The reason I liked to buy xpa3 is to augment 708s power. I currently biamped Rx6 with 708's surrounds and heard a big difference but still trying to know if it's because of upgrading my speaker wires or toeing in the fronts a little. Anyway, my question is how can I biamp my RX6 with xpa3? Would there be a problem if I use 2 channels of xpa3 to power the RX6's bass woofer while leaving the surround channel of 708 connected to power Rx6's tweeter/mid? Or leave 708 biamping the RX6 while xpa3 biamping the RX centre?

Hoping to hear some suggestions from you guys. Thanks
