My set-up is listed in my sig but I'll repeat it for the sake of it.
Onkyo TX - SR701
Polk RTI 12
Polk Monitor T8
Polk PSW 10
I currently am shopping for a good center and rear center channel speaker and wasn't sure what to get. I've just been replaceing stuff as it broke and when the orginal reciver blew up I demoted the t8's to rear surrounds and bought the rti12's with the onkyo reciver powering it all. So if anyone has any ideas I'm all ears :)
