I am looking for speaker recommendations for my 13' L by 10' W room. I would like to have a 7 channel home theatre system. What speakers would you recommend that works well with 990 pre-amp and 7125 amp? Please keep in mind some of the constraints I have:

1. Small size of the room 13 X 10
2. rear speakers will be on the ceiling due to lack of space behind the sofa.

Appreciate your responses.
