All of the previous speakers that have been mentioned are good
However there are two things you need to consider for your Surround/EX
chanels #1 If your are going to use the system for multi-channel music
listening DVA-D,SACD,DTS,PL II ect... then I strongly reccomend that you voice match the surround speakers with the front and center
#2 Looking at your room layout you appear to have a hard angle
on the right rear wall and an opening or slider on the left wall
The hard angle on the left wall will effect the dispersion of a side mounted
Dipole,Bipole or Monopole speaker and the opening on the left wall
will do the same You may be better served in a room that is oddshaped with limited placement for surrounds with something more like this
