Need some input from others

I am putting together my sound system. So far I have a Yamaha RX-V867 and a Polk CSi A4 for my center. I do not have a large room (10 x 14) and am thinking about getting the RTi A3 for the front and am not sure if I should get the RTi A1 for the rear or an older pair of FXi 30. Also, is there a huge difference between the A3 and RTi6. Can get the 6 for a lot less $$.

Thanks
