I just picked up a set of RTi A5s, I already know I want the CSi A6 center, now for the surrounds, I am doing a 5.1 maybe a 5.2 surround sound, I can get the RTi A3 for 275 shipped which are direct firing bookshelf speakers or the FXi A6 for $340 shipped which are dipole/bipole speakers. My HT will be in my living room that is 13' by 25' rectangle however the couch that I will be using as my surround sound "center" will be about 9 feet from the TV and front mains. The area behind the couch will be a sitting area that also opens up to the kitchen. For my purposes will the FXi A6 benefit me or will the rear firing portion of the speakers get lost in the remaining 14 feet to the back wall, not to mention, the open up to the kitchen on one of the walls. I am able to place the RTi A3 speakers directly to the left and right of the seating position and can put them the 2 feet or so above the seating position as recommended, the FXi A6 I would have to put about 4 feet above the seating position. I can also put the FXi A6s on the back wall but at that point the speakers will be 14 feet behind the seating position or even further than my mains will be to the seating position. Will my Pioneer Elite SC-63 be able to fix that? Which speakers should I go with and where should I place them?
