What center Channel should I go with.


I have a pair of Klipsch Choris ii powered by a Yamaha RAV472. I want to add the Klipsch R-12SW Subwoofer. What center channel would be a good fit for mostly playing movies. Should I also buy a amplifier. Any suggestion on subwoofers and center channel speakers and amplifiers?

My budget for the center channel I would like to keep it under 1,000 but for the right speaker I could break that rule.


Thanks for the info

Hi Jay :
I recently upgraded my center from a Focal Electra CC 900 to a Wilson audio. So I will be parting with the Focal. It would be a step up from the Klipsch The CC900 weighs about 50lbs and went for about 1200 when new will be selling it  for 475 plus shipping also have a JL audio sub could send pics if you are interested.  Upgraded the complete HT so have lots of gear etc
