My room is 4.7m x 9.0m in an L-shape with an additional 5m x 3.3m approximately off one end.
Whilst I accept all of your excellent advice so far it still doesn't explain how some people claim that front height speakers can enhance your movie experience and how you actually run these with an existing 7.1 set up.
Can you actually run front height, front wide, surround side and surround back speakers at the same time alongside the normal Left, Centre, Right and subwoofer speakers?
If the answer is yes then what combination of amps/reciever/pre pros would you need?
I see that there is mention of DTS NeoX on the way, I presume this supports more speakers?
Sorry to keep banging on about this but a definitive answer would be good.
Thanks
