I am looking to replace my small Sony satellite rears. I am currently using: SV PCi sub PhaseTech V6 Center BA A60 Left and Right I suspect that I could do better than the Sony's on the rear but don't want anything big or much bigger than they (approx. 4x7in.). I have no idea what to look at. Also, As my room config. is such that the viewing area is against the rear wall I cannot place the rears behind the seating but must put them on the sides. Which is best, side ear level or closer to the ceiling angled down? What about in the wall, perpendicular to the seating facing the listeners sides? Thanks for any help!
